Note: Your site administrator must set up Dependabot updates for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Enabling Dependabot for your enterprise."
About the dependabot.yml file
The Dependabot configuration file, dependabot.yml, uses YAML syntax. If you're new to YAML and want to learn more, see "Learn YAML in five minutes."
You must store this file in the .github directory of your repository in the default branch. When you add or update the dependabot.yml file, this triggers an immediate check for version updates. For more information and an example, see "Configuring Dependabot version updates."
Any options that also affect security updates are used the next time a security alert triggers a pull request for a security update. For more information, see "Configuring Dependabot security updates."
Note: You cannot configure Dependabot alerts using the dependabot.yml file.
The dependabot.yml file has two mandatory top-level keys: version, and updates. You can, optionally, include a top-level registries key. The file must start with version: 2.
For a real-world example of dependabot.yml file, see  Dependabot's own configuration file.
Configuration options for the dependabot.yml file
The top-level updates key is mandatory. You use it to configure how Dependabot updates the versions or your project's dependencies. Each entry configures the update settings for a particular package manager. You can use the following options.
| Option | Required | Security Updates | Version Updates | Description | 
|---|---|---|---|---|
| package-ecosystem | Package manager to use | |||
| directory | Location of package manifests | |||
| schedule.interval | How often to check for updates | |||
| allow | Customize which updates are allowed | |||
| assignees | Assignees to set on pull requests | |||
| commit-message | Commit message preferences | |||
| enable-beta-ecosystems | Enable ecosystems that have beta-level support | |||
| ignore | See ignore | See ignore | Ignore certain dependencies or versions | |
| insecure-external-code-execution | Allow or deny code execution in manifest files | |||
| labels | Labels to set on pull requests | |||
| milestone | Milestone to set on pull requests | |||
| open-pull-requests-limit | Limit number of open pull requests for version updates | |||
| pull-request-branch-name.separator | Change separator for pull request branch names | |||
| rebase-strategy | Disable automatic rebasing | |||
| registries | Private registries that Dependabot can access | |||
| reviewers | Reviewers to set on pull requests | |||
| schedule.day | Day of week to check for updates | |||
| schedule.time | Time of day to check for updates (hh:mm) | |||
| schedule.timezone | Timezone for time of day (zone identifier) | |||
| target-branch | Branch to create pull requests against | |||
| vendor | Update vendored or cached dependencies | |||
| versioning-strategy | How to update manifest version requirements | 
These options fit broadly into the following categories.
- Essential set up options that you must include in all configurations: package-ecosystem,directory,schedule.interval.
- Options to customize the update schedule: schedule.time,schedule.timezone,schedule.day.
- Options to control which dependencies are updated: allow,ignore,vendor.
- Options to add metadata to pull requests: reviewers,assignees,labels,milestone.
- Options to change the behavior of the pull requests: target-branch,versioning-strategy,commit-message,rebase-strategy,pull-request-branch-name.separator.
In addition, the open-pull-requests-limit option changes the maximum number of pull requests for version updates that Dependabot can open.
Note: Some of these configuration options may also affect pull requests raised for security updates of vulnerable package manifests.
Security updates are raised for vulnerable package manifests only on the default branch. When configuration options are set for the same branch (true unless you use target-branch), and specify a package-ecosystem and directory for the vulnerable manifest, then pull requests for security updates use relevant options.
In general, security updates use any configuration options that affect pull requests, for example, adding metadata or changing their behavior. For more information about security updates, see "Configuring Dependabot security updates."
package-ecosystem
Required. You add one package-ecosystem element for each package manager that you want Dependabot to monitor for new versions. The repository must also contain a dependency manifest or lock file for each of these package managers.
If you want to enable vendoring for a package manager that supports it, the vendored dependencies must be located in the required directory. For more information, see vendor below.
If you want to allow Dependabot to access a private package registry when performing a version update, you can include a registries setting in the configuration file. For more information, see registries below.
Note: Enterprise owners can download the most recent version of the Dependabot action to get the best ecosystem coverage. For more information about the action, and for instructions about how to download the most recent version, see "Using the latest version of the official bundled actions."
The following table shows, for each package manager:
- The YAML value to use in the dependabot.ymlfile
- The supported versions of the package manager
- Whether dependencies in private GitHub repositories or registries are supported
- Whether vendored dependencies are supported
| Package manager | YAML value | Supported versions | Private repositories | Private registries | Vendoring | 
|---|---|---|---|---|---|
| Bundler | bundler | v1, v2 | |||
| Cargo | cargo | v1 | (git only) | ||
| Composer | composer | v1, v2 | |||
| Docker | docker | v1 | Not applicable | ||
| Hex | mix | v1 | |||
| elm-package | elm | v0.19 | |||
| git submodule | gitsubmodule | Not applicable | Not applicable | ||
| GitHub Actions | github-actions | Not applicable | Not applicable | ||
| Go modules | gomod | v1 | |||
| Gradle | gradle | Not applicable | |||
| Maven | maven | Not applicable | |||
| npm | npm | v6, v7, v8, v9 | |||
| NuGet | nuget | <= 4.8 | |||
| pip | pip | v21.1.2 | |||
| pipenv | pip | <= 2021-05-29 | |||
| pip-compile | pip | 6.1.0 | |||
| poetry | pip | v1 | |||
| pub | pub | v2 | |||
| Terraform | terraform | >= 0.13, <= 1.5.x | Not applicable | ||
| yarn | npm | v1, v2, v3 | 
Tip: For package managers such as pipenv and poetry, you need to use the pip YAML value. For example, if you use poetry to manage your Python dependencies and want Dependabot to monitor your dependency manifest file for new versions, use package-ecosystem: "pip" in your dependabot.yml file.
Cargo
Private registry support applies to git registries, and doesn't include cargo registries.
Docker
Dependabot can update Docker image tags in Kubernetes manifests. Add an entry to the Docker package-ecosystem element of your dependabot.yml file for each directory containing a Kubernetes manifest which references Docker image tags. Kubernetes manifests can be Kubernetes Deployment YAML files or Helm charts. For information about configuring your dependabot.yml file for docker, see  "package-ecosystem" in "Configuration options for the dependabot.yml file."
Dependabot supports both public and private Docker registries. For a list of the supported registries, see "docker-registry" in "Configuration options for the dependabot.yml file."
Dependabot parses Docker image tags for Semantic Versioning (SemVer). If Dependabot detects a tag with a pre-release, then it will only suggest an update to the latest version with a matching pre-release, and it will not suggest a newer version that use a different pre-release label. For more information, see the dependabot-docker README.md file in the dependabot/dependabot-core repository.
GitHub Actions
Dependabot supports version updates for GitHub Actions with the following caveats.
- Dependabot only supports updates to GitHub Actions using the GitHub repository syntax, such as actions/checkout@v4. Dependabot will ignore actions or reusable workflows referenced locally (for example,./.github/actions/foo.yml).
- Docker Hub and GitHub Packages Container registry URLs are currently not supported. For example, references to Docker container actions using docker://syntax aren't supported.
- Dependabot supports both public and private repositories for GitHub Actions. For private registry configuration options, see "git" in "Configuration options for the dependabot.yml file."
For more information about using Dependabot version updates with GitHub Actions, see "Using GitHub's security features to secure your use of GitHub Actions."
Gradle
Gradle is supported for Dependabot version updates only.
Dependabot doesn't run Gradle but supports updates to the following files:
- build.gradle,- build.gradle.kts(for Kotlin projects)
- Files included via the applydeclaration that havedependenciesin the filename. Note thatapplydoes not supportapply to, recursion, or advanced syntaxes (for example, Kotlin'sapplywithmapOf, filenames defined by property).
Maven
Dependabot doesn't run Maven but supports updates to pom.xml files.
NuGet CLI
Dependabot doesn't run the NuGet CLI but does support most features up until version 4.8.
pip and pip-compile
In addition to supporting updates to requirements.txt files, Dependabot supports updates to pyproject.toml files if they follow the PEP 621 standard.
pnpm
pnpm is supported for Dependabot version updates only. Dependabot security updates are not currently supported.
pub
Dependabot won't perform an update for pub when the version that it tries to update to is ignored, even if an earlier version is available.
Terraform
Terraform support includes:
- Modules hosted on Terraform Registry or a publicly reachable Git repository.
- Terraform providers.
- Private Terraform Registry. You can configure access for private git repositories by specifying a git registry in your dependabot.ymlfile. For more information, seegit.
yarn
Dependabot supports vendored dependencies for v2 onwards.
Example of a basic setup for three package managers
# Basic set up for three package managers
version: 2
updates:
  # Maintain dependencies for GitHub Actions
  - package-ecosystem: "github-actions"
    # Workflow files stored in the default location of `.github/workflows`. (You don't need to specify `/.github/workflows` for `directory`. You can use `directory: "/"`.)
    directory: "/"
    schedule:
      interval: "weekly"
  # Maintain dependencies for npm
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
  # Maintain dependencies for Composer
  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
directory
Required. You must define the location of the package manifests for each package manager (for example, the package.json or Gemfile). You define the directory relative to the root of the repository for all ecosystems except GitHub Actions.
For GitHub Actions, you do not need to set the directory to /.github/workflows. Configuring the key to / automatically instructs Dependabot to search the /.github/workflows directory, as well as the action.yml / action.yaml file from the root directory.
# Specify location of manifest files for each package manager
version: 2
updates:
  - package-ecosystem: "composer"
    # Files stored in repository root
    directory: "/"
    schedule:
      interval: "weekly"
  - package-ecosystem: "npm"
    # Files stored in `app` directory
    directory: "/app"
    schedule:
      interval: "weekly"
  - package-ecosystem: "github-actions"
    # Workflow files stored in the default location of `.github/workflows`. (You don't need to specify `/.github/workflows` for `directory`. You can use `directory: "/"`.)
    directory: "/"
    schedule:
      interval: "weekly"
schedule.interval
Required. You must define how often to check for new versions for each package manager. By default, Dependabot randomly assigns a time to apply all the updates in the configuration file. To set a specific time, you can use schedule.time and schedule.timezone.
Note: The schedule.time option is a best effort, and it may take some time before Dependabot opens pull requests to update to newer dependency versions.
| Interval types | Frequency | 
|---|---|
| daily | Runs on every weekday, Monday to Friday. | 
| weekly | Runs once each week. By default, this is on Monday. To modify this, use schedule.day. | 
| monthly | Runs once each month. This is on the first day of the month. | 
# Set update schedule for each package manager
version: 2
updates:
  - package-ecosystem: "github-actions"
    # Workflow files stored in the default location of `.github/workflows`. (You don't need to specify `/.github/workflows` for `directory`. You can use `directory: "/"`.)
    directory: "/"
    schedule:
      # Check for updates to GitHub Actions every weekday
      interval: "daily"
  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      # Check for updates managed by Composer once a week
      interval: "weekly"
Note: schedule defines when Dependabot attempts a new update. However, it's not the only time you may receive pull requests. Updates can be triggered based on changes to your dependabot.yml file, changes to your manifest file(s) after a failed update, or Dependabot security updates. For more information, see "About Dependabot version updates" and "About Dependabot security updates."
allow
By default all dependencies that are explicitly defined in a manifest are kept up to date by Dependabot version updates. In addition, Dependabot security updates also update vulnerable dependencies that are defined in lock files. You can use allow and ignore to customize which dependencies to maintain. Dependabot checks for all allowed dependencies and then filters out any ignored dependencies or versions. So a dependency that is matched by both an allow and an ignore will be ignored.
Use the allow option to customize which dependencies are updated. This applies to both version and security updates. You can use the following options:
- 
dependency-name—use to allow updates for dependencies with matching names, optionally using*to match zero or more characters.- For Java dependencies, the format of the dependency-nameattribute is:groupId:artifactId; for example:org.kohsuke:github-api.
- For Docker image tags, the format is the full name of the repository; for example, for an image tag of <account ID>.dkr.ecr.us-west-2.amazonaws.com/base/foo/bar/ruby:3.1.0-focal-jemalloc, usebase/foo/bar/ruby.
 
- For Java dependencies, the format of the

dependency-type—use to allow updates for dependencies of specific types.Dependency types Supported by package managers Allow updates directAll All explicitly defined dependencies. indirectbundler,pip,composer,cargoDependencies of direct dependencies (also known as sub-dependencies, or transient dependencies). allAll All explicitly defined dependencies. For bundler,pip,composer,cargo, also the dependencies of direct dependencies.productionbundler,composer,mix,maven,npm,pipOnly dependencies in the "Production dependency group". developmentbundler,composer,mix,maven,npm,pipOnly dependencies in the "Development dependency group".

      - dependency-name: "sphinx"
        dependency-type: "production"
assignees
Use assignees to specify individual assignees for all pull requests raised for a package manager.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Specify assignees for pull requests
version: 2
updates:
  - package-ecosystem: "npm"

    schedule:
      interval: "weekly"
    # Add assignees
    assignees:
      - "octocat"
commit-message
By default, Dependabot attempts to detect your commit message preferences and use similar patterns. Use the commit-message option to specify your preferences explicitly.
Supported options
Note: The prefix and the prefix-development options have a 50-character limit.
- 
prefixspecifies a prefix for all commit messages. When you specify a prefix for commit messages, GitHub will automatically add a colon between the defined prefix and the commit message provided the defined prefix ends with a letter, number, closing parenthesis, or closing bracket. This means that, for example, if you end the prefix with a whitespace, there will be no colon added between the prefix and the commit message. The code snippet below provides examples of both in the same configuration file.
- 
prefix-developmentspecifies a separate prefix for all commit messages that update dependencies in the Development dependency group. When you specify a value for this option, theprefixis used only for updates to dependencies in the Production dependency group. This is supported by:bundler,composer,mix,maven,npm, andpip.
- 
include: "scope"specifies that any prefix is followed by a list of the dependencies updated in the commit.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Customize commit messages
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:

      # Prefix all commit messages with "npm: "
      prefix: "npm"
  - package-ecosystem: "docker"
    directory: "/"
    schedule:
      interval: "weekly"
    commit-message:
      # Prefix all commit messages with "[docker] " (no colon, but a trailing whitespace)
      prefix: "[docker] "
  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
    # Prefix all commit messages with "Composer" plus its scope, that is, a
    # list of updated dependencies
    commit-message:
      prefix: "Composer"
      include: "scope"
  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Include a list of updated dependencies
    # with a prefix determined by the dependency group
    commit-message:
      prefix: "pip prod"
      prefix-development: "pip dev"
      include: "scope"
If you use the same configuration as in the example above, bumping the requests library in the pip development dependency group will generate a commit message of:
pip dev: bump requests from 1.0.0 to 1.0.1
ignore
By default all dependencies that are explicitly defined in a manifest are kept up to date by Dependabot version updates. In addition, Dependabot security updates also update vulnerable dependencies that are defined in lock files. You can use allow and ignore to customize which dependencies to maintain. Dependabot checks for all allowed dependencies and then filters out any ignored dependencies or versions. So a dependency that is matched by both an allow and an ignore will be ignored.
Dependencies can be ignored either by adding them to ignore or by using the @dependabot ignore command on a pull request opened by Dependabot.
Warning:
- 
We recommend you do not use ignoreto prevent Dependabot from accessing private registries. This may work for some ecosystems but we have no means of knowing whether package managers require access to all dependencies to be able to successfully perform updates, which makes this method unreliable. The supported way to handle private dependencies is to give Dependabot access to private registries or private repositories. For more information, see "Configuring access to private registries for Dependabot."
- 
For GitHub Actions and Docker, you may use ignoreto prevent Dependabot from accessing private registries.
Creating ignore conditions from @dependabot ignore
Dependencies ignored by using the @dependabot ignore command are stored centrally for each package manager. If you start ignoring dependencies in the dependabot.yml file, these existing preferences are considered alongside the ignore dependencies in the configuration.
You can check whether a repository has stored ignore preferences by searching the repository for "@dependabot ignore" in:comments, or by using the @dependabot show DEPENDENCY_NAME ignore conditions comment command. If you wish to unblock updates for a dependency ignored this way, re-open the pull request. This clears the ignore conditions that were set when the pull request was closed and resumes those Dependabot updates for the dependency. To update the dependency to a newer version, merge the pull request.
For more information about the @dependabot ignore commands, see "Managing pull requests for dependency updates."
Specifying dependencies and versions to ignore
You can use the ignore option to customize which dependencies are updated. The ignore option supports the following options.
| Option | Description | 
|---|---|
| dependency-name | Use to ignore updates for dependencies with matching names, optionally using *to match zero or more characters.For Java dependencies, the format of the dependency-nameattribute is:groupId:artifactId(for example:org.kohsuke:github-api).To prevent Dependabot from automatically updating TypeScript type definitions from DefinitelyTyped, use @types/*. | 
| versions | Use to ignore specific versions or ranges of versions. If you want to define a range, use the standard pattern for the package manager. For example, for npm, use ^1.0.0; for Bundler, use~> 2.0; for Docker, use Ruby version syntax; for NuGet, use7.*. | 
| update-types | Use to ignore types of updates, such as semver major,minor, orpatchupdates on version updates (for example:version-update:semver-patchwill ignore patch updates). You can combine this withdependency-name: "*"to ignore particularupdate-typesfor all dependencies.Currently, version-update:semver-major,version-update:semver-minor, andversion-update:semver-patchare the only supported options. | 
When used alone, the ignore.versions key affects both Dependabot updates, but the ignore.update-types key affects only Dependabot version updates.
However, if versions and update-types are used together in the same ignore rule, both Dependabot updates are affected, unless the configuration uses target-branch to check for version updates on a non-default branch.
# Use `ignore` to specify dependencies that should not be updated
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    ignore:
      - dependency-name: "express"
        # For Express, ignore all Dependabot updates for version 4 and 5
        versions: ["4.x", "5.x"]
        # For Lodash, ignore all updates
      - dependency-name: "lodash"
        # For AWS SDK, ignore all patch updates for version updates only
      - dependency-name: "aws-sdk"
        update-types: ["version-update:semver-patch"]
  - package-ecosystem: 'github-actions'
    directory: '/'
    schedule:
      interval: 'weekly'
    ignore:
      - dependency-name: 'actions/checkout'
        # For GitHub Actions, ignore all updates greater than or equal to version 3
        versions: '>= 3'
Note: Dependabot can only run version updates on manifest or lock files if it can access all of the dependencies in the file, even if you add inaccessible dependencies to the ignore option of your configuration file. For more information, see "Managing security and analysis settings for your organization" and "Troubleshooting Dependabot errors."
Note: For the pub ecosystem, Dependabot won't perform an update when the version that it tries to update to is ignored, even if an earlier version is available.
insecure-external-code-execution
Package managers with the package-ecosystem values bundler, mix, and pip may execute external code in the manifest as part of the version update process. This might allow a compromised package to steal credentials or gain access to configured registries. When you add a registries setting within an updates configuration, Dependabot automatically prevents external code execution, in which case the version update may fail. You can choose to override this behavior and allow external code execution for bundler, mix, and pip package managers by setting insecure-external-code-execution to allow.
# Allow external code execution when updating dependencies from private registries
version: 2
registries:
  ruby-github:
    type: rubygems-server
    url: https://rubygems.pkg.github.com/octocat/github_api
    token: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}
updates:
  - package-ecosystem: "bundler"
    directory: "/rubygems-server"
    insecure-external-code-execution: allow
    registries: "*"
    schedule:
      interval: "monthly"
If you define a registries setting to allow Dependabot to access a private package registry, and you set insecure-external-code-execution to allow in the same updates configuration, external code execution that occurs will only have access to the package managers in the registries associated with that updatessetting. There is no access allowed to any of the registries defined in the top level registries configuration.
In this example, the configuration file allows Dependabot to access the ruby-github private package registry. In the same updatessetting, insecure-external-code-executionis set to allow, which means that the code executed by dependencies will only access the ruby-github registry, and not the dockerhub registry.
# Using `registries` in conjunction with `insecure-external-code-execution:allow`
# in the same `updates` setting
version: 2
registries:
  ruby-github:
    type: rubygems-server
    url: https://rubygems.pkg.github.com/octocat/github_api
    token: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}
  dockerhub:
    type: docker-registry
    url: registry.hub.docker.com
    username: octocat
    password: ${{secrets.DOCKERHUB_PASSWORD}}
updates:
  - package-ecosystem: "bundler"
    directory: "/rubygems-server"
    insecure-external-code-execution: allow
    registries:
      - ruby-github # only access to registries associated with this ecosystem/directory
    schedule:
      interval: "monthly"
You can explicitly deny external code execution, regardless of whether there is a registries setting for this update configuration, by setting insecure-external-code-execution to deny.
labels
By default, Dependabot raises all pull requests with the dependencies label. If more than one package manager is defined, Dependabot includes an additional label on each pull request. This indicates which language or ecosystem the pull request will update, for example: java for Gradle updates and submodules for git submodule updates. Dependabot creates these default labels automatically, as necessary in your repository.
Use labels to override the default labels and specify alternative labels for all pull requests raised for a package manager. If any of these labels is not defined in the repository, it is ignored.
To disable all labels, including the default labels, use labels: [ ].
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Specify labels for pull requests
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Specify labels for npm pull requests
    labels:
      - "npm"
      - "dependencies"
milestone
Use milestone to associate all pull requests raised for a package manager with a milestone. You need to specify the numeric identifier of the milestone and not its label. If you view a milestone, the final part of the page URL, after milestone, is the identifier. For example: https://github.com/<org>/<repo>/milestone/3.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Specify a milestone for pull requests
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Associate pull requests with milestone "4"
    milestone: 4
open-pull-requests-limit
By default, Dependabot opens a maximum of five pull requests for version updates. Once there are five open pull requests from Dependabot, Dependabot will not open any new requests until some of those open requests are merged or closed. Use open-pull-requests-limit to change this limit. This also provides a simple way to temporarily disable version updates for a package manager.
This option has no impact on security updates, which have a separate, internal limit of ten open pull requests.
# Specify the number of open pull requests allowed
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Disable version updates for npm dependencies
    open-pull-requests-limit: 0
  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Allow up to 10 open pull requests for pip dependencies
    open-pull-requests-limit: 10
pull-request-branch-name.separator
Dependabot generates a branch for each pull request. Each branch name includes dependabot, and the package manager and dependency that are updated. By default, these parts are separated by a / symbol, for example: dependabot/npm_and_yarn/next_js/acorn-6.4.1.
Use pull-request-branch-name.separator to specify a different separator. This can be one of: "-", _ or /. The hyphen symbol must be quoted because otherwise it's interpreted as starting an empty YAML list.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Specify a different separator for branch names
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    pull-request-branch-name:
      # Separate sections of the branch name with a hyphen
      # for example, `dependabot-npm_and_yarn-next_js-acorn-6.4.1`
      separator: "-"
rebase-strategy
By default, Dependabot automatically rebases open pull requests when it detects any changes to the pull request. Use rebase-strategy to disable this behavior.
Available rebase strategies
- autoto use the default behavior and rebase open pull requests when changes are detected.
- disabledto disable automatic rebasing.
When rebase-strategy is set to auto, Dependabot attempts to rebase pull requests in the following cases.
- When you use Dependabot version updates, for any open Dependabot pull request when your schedule runs.
- When you reopen a closed Dependabot pull request.
- When you change the value of target-branchin the Dependabot configuration file. For more information about this field, see "target-branch."
- When Dependabot detects that a Dependabot pull request is in conflict after a recent push to the target branch.
Note: Dependabot will keep rebasing a pull request indefinitely until the pull request is closed, merged or you disable Dependabot updates.
When rebase-strategy is set to disabled, Dependabot stops rebasing pull requests.
Note: This behavior only applies to pull requests that go into conflict with the target branch. Dependabot will keep rebasing  pull requests opened prior to the rebase-strategy setting being changed, and pull requests that are part of a scheduled run.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.

registries
To allow Dependabot to access a private package registry when performing a version update, you must include a registries setting within the relevant updates configuration. You can allow all of the defined registries to be used by setting registries to "*".
# Allow Dependabot to use all the defined registries
version: 2
registries: "*"
Alternatively, you can list the registries that the update can use. To do this, use the name of the registry as defined in the top-level registries section of the dependabot.yml file. For more information, see "Configuration options for private registries" below.
For in-depth information about available options, as well as recommendations and advice when configuring private registries, see "Guidance for the configuration of private registries for Dependabot."
To allow Dependabot to use bundler, mix, and pip package managers to update dependencies in private registries, you can choose to allow external code execution. For more information, see insecure-external-code-execution above.
# Allow Dependabot to use one of the two defined private registries
# when updating dependency versions for this ecosystem

    schedule:
      interval: "monthly"
reviewers
Use reviewers to specify individual reviewers or teams of reviewers for all pull requests raised for a package manager. You must use the full team name, including the organization, as if you were @mentioning the team.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
# Specify reviewers for pull requests

      - "my-username"
      - "my-org/python-team"
schedule.day
When you set a weekly update schedule, by default, Dependabot checks for new versions on Monday at a random set time for the repository. Use schedule.day to specify an alternative day to check for updates.
Supported values
- monday
- tuesday
- wednesday
- thursday
- friday
- saturday
- sunday
# Specify the day for weekly checks
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates on Sundays
      day: "sunday"
schedule.time
By default, Dependabot checks for new versions at a random set time for the repository. Use schedule.time to specify an alternative time of day to check for updates (format: hh:mm).
# Set a time for checks
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates at 9am UTC
      time: "09:00"
schedule.timezone
By default, Dependabot checks for new versions at a random set time for the repository. Use schedule.timezone to specify an alternative time zone. The time zone identifier must be from the Time Zone database maintained by iana. For more information, see List of tz database time zones.
# Specify the timezone for checks
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      time: "09:00"
      # Use Japan Standard Time (UTC +09:00)
      timezone: "Asia/Tokyo"
target-branch
By default, Dependabot checks for manifest files on the default branch and raises pull requests for version updates against this branch. Use target-branch to specify a different branch for manifest files and for pull requests. When you use this option, the settings for this package manager will no longer affect any pull requests raised for security updates.
# Specify a non-default branch for pull requests for pip
version: 2
updates:
  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Raise pull requests for version updates
    # to pip against the `develop` branch
    target-branch: "develop"
    # Labels on pull requests for version updates only
    labels:
      - "pip dependencies"
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates on Sundays
      day: "sunday"
    # Labels on pull requests for security and version updates
    labels:
      - "npm dependencies"
vendor
Use the vendor option to tell Dependabot to vendor dependencies when updating them. Don't use this option if you're using gomod as Dependabot automatically detects vendoring for this tool.
# Configure version updates for both dependencies defined in manifests and vendored dependencies
version: 2
updates:
  - package-ecosystem: "bundler"
    # Raise pull requests to update vendored dependencies that are checked in to the repository
    vendor: true
    directory: "/"
    schedule:
      interval: "weekly"
Dependabot only updates the vendored dependencies located in specific directories in a repository.
| Package manager | Required file path for vendored dependencies | More information | 
|---|---|---|
| bundler | The dependencies must be in the vendor/cache directory. Other file paths are not supported. | bundle cachedocumentation | 
| gomod | No path requirement (dependencies are usually located in the vendor directory) | go mod vendordocumentation | 
versioning-strategy
When Dependabot edits a manifest file to update a version, there are several different potential versioning strategies:
| Option | Action | 
|---|---|
| auto | Try to differentiate between apps and libraries. Use increasefor apps andwidenfor libraries. | 
| increase | Always increase the minimum version requirement to match the new version. If a range already exists, typically this only increases the lower bound. | 
| increase-if-necessary | Leave the constraint if the original constraint allows the new version, otherwise, bump the constraint. | 
| lockfile-only | Only create pull requests to update lockfiles. Ignore any new versions that would require package manifest changes. | 
| widen | Widen the allowed version requirements to include both the new and old versions, when possible. Typically, this only increases the maximum allowed version requirement. | 
| N/A | Some package managers do not yet support configuring the versioning-strategyparameter. | 
The following table shows an example of how versioning-strategy can be used.
| Current constraint | Current version | New version | Strategy | New constraint | 
|---|---|---|---|---|
| ^1.0.0 | 1.0.0 | 1.2.0 | widen | ^1.0.0 | 
| ^1.0.0 | 1.0.0 | 1.2.0 | increase | ^1.2.0 | 
| ^1.0.0 | 1.0.0 | 1.2.0 | increase-if-necessary | ^1.0.0 | 
| ^1.0.0 | 1.0.0 | 2.0.0 | widen | >=1.0.0 <3.0.0 | 
| ^1.0.0 | 1.0.0 | 2.0.0 | increase | ^2.0.0 | 
| ^1.0.0 | 1.0.0 | 2.0.0 | increase-if-necessary | ^2.0.0 | 
Use the versioning-strategy option to change this behavior for supported package managers.
Setting this option will also affect pull requests for security updates to the manifest files of this package manager, unless you use target-branch to check for version updates on a non-default branch.
Available update strategies:
| Ecosystem | Supported versioning strategies | Default strategy | 
|---|---|---|
| bundler | auto,increase,increase-if-necessary,lockfile-only | auto | 
| cargo | auto,lockfile-only | auto | 
| composer | auto,increase,increase-if-necessary,lockfile-only,widen | auto | 
| docker | N/A | N/A | 
| github-actions | N/A | N/A | 
| gitsubmodule | N/A | N/A | 
| gomod | N/A | N/A | 
| gradle | N/A | N/A | 
| maven | N/A | N/A | 
| mix | auto,lockfile-only | auto | 
| npm | auto,increase,increase-if-necessary,lockfile-only,widen | auto | 
| nuget | N/A | N/A | 
| pip | auto,increase,increase-if-necessary,lockfile-only | auto | 
| pub | auto,increase,increase-if-necessary,widen | auto | 
| terraform | N/A | N/A | 
Note: N/A indicates that the package manager does not yet support configuring the versioning-strategy parameter. The strategy code is open source, so if you'd like a particular ecosystem to support a new strategy, you are always welcome to submit a pull request in https://github.com/dependabot/dependabot-core/.
# Example configuration for customizing the manifest version strategy
version: 2
updates:
  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
    # Increase the version requirements for Composer only when required
    versioning-strategy: increase-if-necessary
Configuration options for private registries
The top-level registries key is optional. It allows you to specify authentication details that Dependabot can use to access private package registries.
You can give Dependabot access to private package registries hosted by GitLab or Bitbucket by specifying a type of git. For more information, see git.
Note: Private registries behind firewalls on private networks are supported for the following ecosystems:
- Bundler
- Docker
- Gradle
- Maven
- npm
- Nuget
- Python
- Yarn
The value of the registries key is an associative array, each element of which consists of a key that identifies a particular registry and a value which is an associative array that specifies the settings required to access that registry. The following dependabot.yml file configures a registry identified as dockerhub in the registries section of the file and then references this in the updates section of the file.
# Minimal settings to update dependencies in one private registry
version: 2
registries:
  dockerhub: # Define access for a private registry
    type: docker-registry
    url: registry.hub.docker.com
    username: octocat
    password: ${{secrets.DOCKERHUB_PASSWORD}}
updates:
  - package-ecosystem: "docker"
    directory: "/docker-registry/dockerhub"
    registries:
      - dockerhub # Allow version updates for dependencies in this registry
    schedule:
      interval: "monthly"
You use the following options to specify access settings. Registry settings must contain a type and a url, and typically either a username and password combination or a token.
| Option | Description | 
|---|---|
| type | Identifies the type of registry. See the full list of types below. | 
| url | The URL to use to access the dependencies in this registry. The protocol is optional. If not specified, https://is assumed. Dependabot adds or ignores trailing slashes as required. | 
| username | The username that Dependabot uses to access the registry. usernameis the username or email address for the account. | 
| password | A reference to a Dependabot secret containing the password for the specified user. For more information, see "Configuring access to private registries for Dependabot." passwordis the password for the account specified by the username. If the account is a GitHub account, you can use a GitHub personal access token in place of the password. | 
| key | A reference to a Dependabot secret containing an access key for this registry. For more information, see "Configuring access to private registries for Dependabot." | 
| token | A reference to a Dependabot secret containing an access token for this registry. For more information, see "Configuring access to private registries for Dependabot." tokenis used to provide an access token for an external system and should not be used to provide a GitHub personal access token. If you want to use a GitHub personal access token, you should supply it as a password. | 
| replaces-base | For registries, if the boolean value is true, Dependabot will resolve dependencies by using the specified URL rather than the base URL of that specific ecosystem. For example, for registries withtype: python-index, if the boolean value istrue, pip resolves dependencies by using the specified URL rather than the base URL of the Python Package Index (by defaulthttps://pypi.org/simple). | 
You must provide the required settings for each configuration type that you specify. Some types allow more than one way to connect. The following sections provide details of the settings you should use for each type.
For in-depth information about available options, as well as recommendations and advice when configuring private registries, see "Guidance for the configuration of private registries for Dependabot."
composer-repository
The composer-repository type supports username and password. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
This registry type will prefix-match the path provided in the url option. This means you can provide multiple credentials to the same host, which can be used to access distinct paths. However, if you don't have multiple registries on the same host, we recommend that you omit the path from the url, so that all paths to the registry will receive credentials.
registries:
  composer:
    type: composer-repository
    url: https://repo.packagist.com/example-company/
    username: octocat
    password: ${{secrets.MY_PACKAGIST_PASSWORD}}
docker-registry
Dependabot works with any container registries that implement the OCI container registry spec. For more information, see https://github.com/opencontainers/distribution-spec/blob/main/spec.md. Dependabot supports authentication to private registries via a central token service or HTTP Basic Auth. For further details, see Token Authentication Specification in the Docker documentation and Basic access authentication on Wikipedia.
The docker-registry type supports username and password. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
This registry type will prefix-match the path provided in the url option. This means you can provide multiple credentials to the same host, which can be used to access distinct paths. However, if you don't have multiple registries on the same host, we recommend that you omit the path from the url, so that all paths to the registry will receive credentials.
registries:

The docker-registry type can also be used to pull from private Amazon ECR using static AWS credentials.
registries:
  ecr-docker:
    type: docker-registry
    url: https://1234567890.dkr.ecr.us-east-1.amazonaws.com
    username: ${{secrets.ECR_AWS_ACCESS_KEY_ID}}
    password: ${{secrets.ECR_AWS_SECRET_ACCESS_KEY}}
    replaces-base: true
git
The git type supports username and password. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
registries:
  github-octocat:
    type: git
    url: https://github.com
    username: x-access-token
    password: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}
hex-organization
The hex-organization type supports organization and key.
This registry type will prefix-match the path provided in the url option. This means you can provide multiple credentials to the same host, which can be used to access distinct paths. However, if you don't have multiple registries on the same host, we recommend that you omit the path from the url, so that all paths to the registry will receive credentials.
registries:
  github-hex-org:
    type: hex-organization
    organization: github
    key: ${{secrets.MY_HEX_ORGANIZATION_KEY}}
hex-repository
The hex-repository type supports an authentication key.
repo is a required field, which must match the name of the repository used in your dependency declaration.
The public-key-fingerprint is an optional configuration field, representing the fingerprint of the public key for the Hex repository. public-key-fingerprint is used by Hex to establish trust with the private repository. The public-key-fingerprint field can be either listed in plaintext or stored as a Dependabot secret.
registries:
   github-hex-repository:
     type: hex-repository
     repo: private-repo
     url: https://private-repo.example.com
     auth-key: ${{secrets.MY_AUTH_KEY}}
     public-key-fingerprint: ${{secrets.MY_PUBLIC_KEY_FINGERPRINT}}
maven-repository
The maven-repository type supports username and password. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
This registry type will prefix-match the path provided in the url option. This means you can provide multiple credentials to the same host, which can be used to access distinct paths. However, if you don't have multiple registries on the same host, we recommend that you omit the path from the url, so that all paths to the registry will receive credentials.
registries:
  maven-artifactory:
    type: maven-repository
    url: https://acme.jfrog.io/artifactory/my-maven-registry
    username: octocat
    password: ${{secrets.MY_ARTIFACTORY_PASSWORD}}
npm-registry
The npm-registry type supports username and password, or token. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
When using username and password, your .npmrc's auth token may contain a base64 encoded _password; however, the password referenced in your Dependabot configuration file must be the original (unencoded) password.
Note: When using npm.pkg.github.com, don't include a path. Instead use the https://npm.pkg.github.com URL without a path.
registries:
  npm-npmjs:
    type: npm-registry
    url: https://registry.npmjs.org
    username: octocat
    password: ${{secrets.MY_NPM_PASSWORD}}  # Must be an unencoded password

  npm-github:
    type: npm-registry
    url: https://npm.pkg.github.com
    token: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}
    replaces-base: true
For security reasons, Dependabot does not set environment variables. Yarn (v2 and later) requires that any accessed environment variables are set. When accessing environment variables in your .yarnrc.yml file, you should provide a fallback value such as ${ENV_VAR-fallback} or ${ENV_VAR:-fallback}. For more information, see Yarnrc files in the Yarn documentation.
nuget-feed
The nuget-feed type supports username and password, or token. If the account is a GitHub account, you can use a GitHub personal access token in place of the password.
