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

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.

不明なビルドステップや部分的に成功したパイプラインなど、GitHub Actions Importer で自動的に変換できなかったものがある場合は、カスタムトランスフォーマーを作成して変換プロセスをさらにカスタマイズできます。詳しくは、「Extending GitHub Actions Importer with custom transformers」をご覧ください。

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'

pull request の検査

migrate コマンドが正常に実行された場合、出力には、変換されたワークフローをリポジトリに追加する新しい pull request へのリンクが含まれます。

pull request の重要な要素には、次のようなものがあります。

pull request の説明の「手動ステップ」というセクションには、パイプラインの GitHub Actions への移行を終了する前に手動で完了する必要があるステップが列挙されています。たとえば、このセクションでは、ワークフローで使われるシークレットを作成するように指示する場合があります。
変換されたワークフローファイル。 Pull request の [Files changed] タブを選んで、GitHub リポジトリに追加されるワークフローファイルを表示します。

Pull request の検査が終了したら、それをマージして、ワークフローを GitHub リポジトリに追加できます。

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 では、認証構成に環境変数が使われます。これらの変数は、configure コマンドを使って構成プロセスに従うことで設定します。詳細については、資格情報の構成に関するセクションを参照してください。

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

GitHub Actions Importer サブコマンドと一緒に使って、移行をカスタマイズできる省略可能な引数があります。

`--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
