Migrating from GitLab with GitHub Actions Importer

About migrating from GitLab with GitHub Actions Importer

The instructions below will guide you through configuring your environment to use GitHub Actions Importer to migrate GitLab pipelines to GitHub Actions.

Prerequisites

A GitLab account or organization with pipelines and jobs that you want to convert to GitHub Actions workflows.
Access to create a GitLab personal access token for your account or organization.
Eine Umgebung, in der du Linux-basierte Container ausführen und die erforderlichen Tools installieren kannst:
- Docker ist installiert und wird ausgeführt.
- Die GitHub-CLI ist installiert.
Hinweis

Der GitHub Actions Importer-Container und die CLI müssen nicht auf demselben Server wie deine CI-Plattform installiert werden.

Limitations

There are some limitations on migrating processes automatically from GitLab pipelines to GitHub Actions with GitHub Actions Importer.

Automatic caching in between jobs of different workflows is not supported.
The audit command is only supported when using an organization account. However, the dry-run and migrate commands can be used with an organization or user account.

Manual tasks

Certain GitLab constructs must be migrated manually. These include:

Masked project or group variable values
Artifact reports

For more information on manual migrations, see Migrating from GitLab CI/CD to GitHub Actions.

Installing the GitHub Actions Importer CLI extension

So installierst du die GitHub Actions Importer-CLI-Erweiterung:

Bash

gh extension install github/gh-actions-importer

gh extension install github/gh-actions-importer

Überprüfe, ob die Erweiterung installiert ist:

$ gh actions-importer -h

Configuring credentials

The configure CLI command is used to set required credentials and options for GitHub Actions Importer when working with GitLab and GitHub.

Create a GitHub personal access token (classic). For more information, see Verwalten deiner persönlichen Zugriffstoken.

Your token must have the workflow scope.

After creating the token, copy it and save it in a safe location for later use.
Create a GitLab personal access token. For more information, see Personal access tokens in the GitLab documentation.

Your token must have the read_api scope.

After creating the token, copy it and save it in a safe location for later use.
In your terminal, run the GitHub Actions Importer configure CLI command:
```
gh actions-importer configure
```
The configure command will prompt you for the following information:
- For "Which CI providers are you configuring?", use the arrow keys to select GitLab, press Space to select it, then press Enter.
- For "Personal access token for GitHub", enter the value of the personal access token (classic) that you created earlier, and press Enter.
- For "Base url of the GitHub instance", press Enter to accept the default value (https://github.com).
- For "Private token for GitLab", enter the value for the GitLab personal access token that you created earlier, and press Enter.
- For "Base url of the GitLab instance", enter the URL of your GitLab instance, and press Enter.
An example of the output of the configure command is shown below.
```
$ gh actions-importer configure
✔ Which CI providers are you configuring?: GitLab
Enter the following values (leave empty to omit):
✔ Personal access token for GitHub: ***************
✔ Base url of the GitHub instance: https://github.com
✔ Private token for GitLab: ***************
✔ Base url of the GitLab instance: http://localhost
Environment variables successfully updated.
```
In your terminal, run the GitHub Actions Importer update CLI command to connect to GitHub Packages Container registry and ensure that the container image is updated to the latest version:
```
gh actions-importer update
```
The output of the command should be similar to below:
```
Updating ghcr.io/actions-importer/cli:latest...
ghcr.io/actions-importer/cli:latest up-to-date
```

Perform an audit of GitLab

You can use the audit command to get a high-level view of all pipelines in a GitLab server.

The audit command performs the following steps:

Fetches all of the projects defined in a GitLab server.
Converts each pipeline to its equivalent GitHub Actions workflow.
Generates a report that summarizes how complete and complex of a migration is possible with GitHub Actions Importer.

Prerequisites for the audit command

In order to use the audit command, you must have a personal access token configured with a GitLab organization account.

Running the audit command

To perform an audit of a GitLab server, run the following command in your terminal, replacing my-gitlab-namespace with the namespace or group you are auditing:

gh actions-importer audit gitlab --output-dir tmp/audit --namespace my-gitlab-namespace

Inspecting the audit results

Die Dateien im angegebenen Ausgabeverzeichnis enthalten die Ergebnisse der Überprüfung. Eine Zusammenfassung der Überprüfungsergebnisse findest du in der Datei audit_summary.md.

Die Überprüfungszusammenfassung enthält die folgenden Abschnitte.

Pipelines

Der Abschnitt „Pipelines“ enthält eine allgemeine Statistik zur Konvertierungsrate durch den GitHub Actions Importer.

Im Folgenden sind einige wichtige Begriffe aufgeführt, die im Abschnitt „Pipelines“ enthalten sein können:

Bei erfolgreichen Pipelines wurden 100 % der Pipelinekonstrukte und Einzelelemente automatisch in ihre GitHub Actions-Entsprechung konvertiert.
Bei teilweise erfolgreichen Pipelines wurden zwar alle Pipelinekonstrukte, aber nicht alle Einzelelemente automatisch in ihre GitHub Actions-Entsprechung konvertiert.
Nicht unterstützte Pipelines sind Definitionstypen, die vom GitHub Actions Importer nicht unterstützt werden.
Bei fehlerhaften Pipelines ist beim Konvertieren ein schwerwiegender Fehler aufgetreten. Dies kann aus drei Gründen auftreten:
- Die Pipeline war ursprünglich falsch konfiguriert und nicht gültig.
- Der GitHub Actions Importer hat beim Konvertieren ein interner Fehler festgestellt.
- Es gab eine nicht erfolgreiche Netzwerkantwort, die dazu führte, dass auf die Pipeline nicht zugegriffen werden konnte. Dies ist häufig auf ungültige Anmeldeinformationen zurückzuführen.

Buildschritte

Der Abschnitt „Buildschritte“ enthält eine Übersicht über die einzelnen Buildschritte, die in allen Pipelines verwendet werden, und darüber, wie viele davon vom GitHub Actions Importer automatisch konvertiert wurden.

Im Folgenden sind einige wichtige Begriffe aufgeführt, die im Abschnitt „Buildschritte“ enthalten sein können:

Ein bekannter Buildschritt ist ein Schritt, der automatisch in eine entsprechende Aktion konvertiert wurde.
Ein unbekannter Buildschritt ist ein Schritt, der nicht automatisch in eine entsprechende Aktion konvertiert wurde.
Ein nicht unterstützter Buildschritt ist ein Schritt, für den eine der folgenden Aussagen zutrifft:
- Er wird grundsätzlich von GitHub Actions nicht unterstützt.
- Seine Konfiguration ist mit GitHub Actions nicht kompatibel.
Eine Aktion ist eine Liste der Aktionen, die in den konvertierten Workflows verwendet wurden. Dies kann für Folgendes wichtig sein:
- Zum Sammeln der Liste der Aktionen, die mit deiner Instanz synchronisiert werden sollen, sofern du GitHub Enterprise Server verwendest
- Zum Definieren einer Positivliste der verwendeten Aktionen auf Organisationsebene. Diese Aktionenliste enthält sämtliche Aktionen, die von den Sicherheits- oder Complianceteams möglicherweise überprüft werden müssen.

Manuelle Aufgaben

Der Abschnitt „Manuelle Aufgaben“ enthält eine Übersicht über Aufgaben, die der GitHub Actions Importer nicht automatisch ausführen kann und die du manuell ausführen musst.

Im Folgenden sind einige wichtige Begriffe aufgeführt, die im Abschnitt „Manuelle Aufgaben“ enthalten sein können:

Ein Geheimnis gilt auf Repository- oder Organisationsebene und wird in den konvertierten Pipelines verwendet. Diese Geheimnisse müssen manuell in GitHub Actions erstellt werden, damit diese Pipelines ordnungsgemäß funktionieren. Weitere Informationen finden Sie unter Using secrets in GitHub Actions.
Selbstgehosteter Runner ist eine Bezeichnung für Runner, auf die in einer konvertierten Pipeline verwiesen wird, und die nicht von GitHub gehostet werden. Du musst diese Runner manuell definieren, damit diese Pipelines ordnungsgemäß funktionieren.

Dateien

Der letzte Abschnitt des Überprüfungsberichts enthält ein Manifest aller Dateien, die während der Überprüfung auf den Datenträger geschrieben wurden.

Für jede Pipelinedatei werden verschiedene Dateien überprüft, z. B.:

Die ursprüngliche Pipeline, wie in GitHub definiert
Alle Netzwerkantworten, die zum Konvertieren der Pipeline verwendet werden
Die konvertierte Workflowdatei
Stapelablaufverfolgungen, die zur Problembehandlung bei einer fehlerhaften Pipelinekonvertierung verwendet werden können

Darüber hinaus enthält die Datei workflow_usage.csv eine durch Trennzeichen getrennte Liste aller Aktionen, Geheimnisse und Runner, die von jeder erfolgreich konvertierten Pipeline verwendet werden. Dies kann nützlich sein, um zu bestimmen, welche Workflows Aktionen, Geheimnisse oder Runner verwenden, und um Sicherheitsüberprüfungen durchzuführen.

Forecast potential build runner usage

You can use the forecast command to forecast potential GitHub Actions usage by computing metrics from completed pipeline runs in your GitLab server.

Running the forecast command

To perform a forecast of potential GitHub Actions usage, run the following command in your terminal, replacing my-gitlab-namespace with the namespace or group you are forecasting. By default, GitHub Actions Importer includes the previous seven days in the forecast report.

gh actions-importer forecast gitlab --output-dir tmp/forecast --namespace my-gitlab-namespace

Forecasting an entire namespace

To forecast an entire namespace and all of its subgroups, you must specify each subgroup in the --namespace argument or NAMESPACE environment variable.

For example:

gh actions-importer forecast gitlab --namespace my-gitlab-namespace my-gitlab-namespace/subgroup-one my-gitlab-namespace/subgroup-two ...

Inspecting the forecast report

The forecast_report.md file in the specified output directory contains the results of the forecast.

Listed below are some key terms that can appear in the forecast report:

The job count is the total number of completed jobs.
The pipeline count is the number of unique pipelines used.
Execution time describes the amount of time a runner spent on a job. This metric can be used to help plan for the cost of GitHub-hosted runners.
- This metric is correlated to how much you should expect to spend in GitHub Actions. This will vary depending on the hardware used for these minutes. You can use the GitHub Actions pricing calculator to estimate the costs.
Queue time metrics describe the amount of time a job spent waiting for a runner to be available to execute it.
Concurrent jobs metrics describe the amount of jobs running at any given time. This metric can be used to define the number of runners you should configure.

Additionally, these metrics are defined for each queue of runners in GitLab. This is especially useful if there is a mix of hosted or self-hosted runners, or high or low spec machines, so you can see metrics specific to different types of runners.

Perform a dry-run migration of a GitLab pipeline

You can use the dry-run command to convert a GitLab pipeline to its equivalent GitHub Actions workflow.

Running the dry-run command

You can use the dry-run command to convert a GitLab pipeline to an equivalent GitHub Actions workflow. A dry-run creates the output files in a specified directory, but does not open a pull request to migrate the pipeline.

To perform a dry run of migrating your GitLab pipelines to GitHub Actions, run the following command in your terminal, replacing my-gitlab-project with your GitLab project slug, and my-gitlab-namespace with the namespace or group (full group path for subgroups, e.g. my-org/my-team) you are performing a dry run for.

gh actions-importer dry-run gitlab --output-dir tmp/dry-run --namespace my-gitlab-namespace --project my-gitlab-project

Inspecting the converted workflows

You can view the logs of the dry run and the converted workflow files in the specified output directory.

Wenn der GitHub Actions Importer etwas nicht automatisch konvertieren konnte (z. B. unbekannte Buildschritte oder eine teilweise erfolgreiche Pipeline), solltest du benutzerdefinierte Transformatoren erstellen, um den Konvertierungsprozess präziser anzupassen. Weitere Informationen finden Sie unter Extending GitHub Actions Importer with custom transformers.

Perform a production migration of a GitLab pipeline

You can use the migrate command to convert a GitLab pipeline and open a pull request with the equivalent GitHub Actions workflow.

Running the migrate command

To migrate a GitLab pipeline to GitHub Actions, run the following command in your terminal, replacing the following values:

target-url value with the URL for your GitHub repository
my-gitlab-project with your GitLab project slug
my-gitlab-namespace with the namespace or group you are migrating (full path for subgroups, e.g. my-org/my-team)

gh actions-importer migrate gitlab --target-url https://github.com/:owner/:repo --output-dir tmp/migrate --namespace my-gitlab-namespace --project my-gitlab-project

The command's output includes the URL to the pull request that adds the converted workflow to your repository. An example of a successful output is similar to the following:

$ gh actions-importer migrate gitlab --target-url https://github.com/octo-org/octo-repo --output-dir tmp/migrate --namespace octo-org --project monas-project
[2022-08-20 22:08:20] Logs: 'tmp/migrate/log/actions-importer-20220916-014033.log'
[2022-08-20 22:08:20] Pull request: 'https://github.com/octo-org/octo-repo/pull/1'

Überprüfen des Pull Requests

Die Ausgabe einer erfolgreichen Ausführung des Befehls migrate enthält einen Link zum neuen Pull Request, mit dem der konvertierte Workflow deinem Repository hinzugefügt wird.

Wichtige Elemente des Pull Requests:

In der Beschreibung des Pull Requests findest du den Abschnitt Manuelle Schritte, in dem Schritte aufgeführt sind, die du manuell ausführen musst, um die Migration deiner Pipelines zu GitHub Actions abschließen zu können. In diesem Abschnitt könnte z. B. stehen, dass du Geheimnisse erstellen musst, die im Workflows verwendet werden.
Die konvertierte Workflowdatei Wähle im Pull Request die Registerkarte Files changed aus, um die Workflowdatei anzuzeigen, die deinem GitHub-Repository hinzugefügt wird.

Nachdem du den Pull Request überprüft hast, kannst du ihn zusammenführen, um den Workflow deinem GitHub-Repository hinzuzufügen.

Reference

This section contains reference information on environment variables, optional arguments, and supported syntax when using GitHub Actions Importer to migrate from GitLab.

Using environment variables

GitHub Actions Importer verwendet Umgebungsvariablen für die Konfiguration der Authentifizierung. Diese Variablen werden beim Ausführen des Konfigurationsvorgangs mithilfe des Befehls configure festgelegt. Weitere Informationen findest du im Abschnitt Konfigurieren von Anmeldeinformationen.

GitHub Actions Importer uses the following environment variables to connect to your GitLab instance:

GITHUB_ACCESS_TOKEN: The personal access token (classic) used to create pull requests with a converted workflow (requires the workflow scope).
GITHUB_INSTANCE_URL: The URL to the target GitHub instance (for example, https://github.com).
GITLAB_ACCESS_TOKEN: The GitLab personal access token used to view GitLab resources.
GITLAB_INSTANCE_URL: The URL of the GitLab instance.
NAMESPACE: The namespaces or groups that contain the GitLab pipelines.

These environment variables can be specified in a .env.local file that is loaded by GitHub Actions Importer when it is run.

Using optional arguments

Es gibt einige optionale Argumente, die du mit den Unterbefehlen von GitHub Actions Importer verwenden kannst, um deine Migration anzupassen.

`--source-file-path`

You can use the --source-file-path argument with the forecast, dry-run, or migrate subcommands.

By default, GitHub Actions Importer fetches pipeline contents from source control. The --source-file-path argument tells GitHub Actions Importer to use the specified source file path instead.

For example:

gh actions-importer dry-run gitlab --output-dir output/ --namespace my-gitlab-namespace --project my-gitlab-project --source-file-path path/to/.gitlab-ci.yml

If you would like to supply multiple source files when running the forecast subcommand, you can use pattern matching in the file path value. The following example supplies GitHub Actions Importer with any source files that match the ./tmp/previous_forecast/jobs/*.json file path.

gh actions-importer forecast gitlab --output-dir output/ --namespace my-gitlab-namespace --project my-gitlab-project --source-file-path ./tmp/previous_forecast/jobs/*.json

`--config-file-path`

You can use the --config-file-path argument with the audit, dry-run, and migrate subcommands.

By default, GitHub Actions Importer fetches pipeline contents from source control. The --config-file-path argument tells GitHub Actions Importer to use the specified source files instead.

The --config-file-path argument can also be used to specify which repository a converted reusable workflow should be migrated to.

Audit example

In this example, GitHub Actions Importer uses the specified YAML configuration file to perform an audit.

gh actions-importer audit gitlab --output-dir path/to/output/ --namespace my-gitlab-namespace --config-file-path path/to/gitlab/config.yml

To audit a GitLab instance using a configuration file, the file must be in the following format, and each repository_slug value must be unique:

source_files:
  - repository_slug: namespace/project-name
    path: path/to/.gitlab-ci.yml
  - repository_slug: namespace/some-other-project-name
    path: path/to/.gitlab-ci.yml

Dry run example

In this example, GitHub Actions Importer uses the specified YAML configuration file as the source file to perform a dry run.

The pipeline is selected by matching the repository_slug in the configuration file to the value of the --namespace and --project options. The path is then used to pull the specified source file.

gh actions-importer dry-run gitlab --namespace my-gitlab-namespace --project my-gitlab-project-name --output-dir ./output/ --config-file-path ./path/to/gitlab/config.yml

Specify the repository of converted reusable workflows

GitHub Actions Importer uses the YAML file provided to the --config-file-path argument to determine the repository that converted reusable workflows are migrated to.

To begin, you should run an audit without the --config-file-path argument:

gh actions-importer audit gitlab --output-dir ./output/

The output of this command will contain a file named config.yml that contains a list of all the composite actions that were converted by GitHub Actions Importer. For example, the config.yml file may have the following contents:

reusable_workflows:
  - name: my-reusable-workflow.yml
    target_url: https://github.com/octo-org/octo-repo
    ref: main

You can use this file to specify which repository and ref a reusable workflow or composite action should be added to. You can then use the --config-file-path argument to provide the config.yml file to GitHub Actions Importer. For example, you can use this file when running a migrate command to open a pull request for each unique repository defined in the config file:

gh actions-importer migrate gitlab --project my-project-name --output-dir output/ --config-file-path config.yml --target-url https://github.com/my-org/my-repo
