About migrating from Azure DevOps with GitHub Actions Importer

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

Prerequisites

  • An Azure DevOps account or organization with projects and pipelines that you want to convert to GitHub Actions workflows.
  • Access to create an Azure DevOps personal access token for your account or organization.
  • Linux 기반 컨테이너를 실행하고 필요한 도구를 설치할 수 있는 환경입니다.

    참고 항목

    GitHub Actions Importer 컨테이너와 CLI는 CI 플랫폼과 동일한 서버에 설치할 필요가 없습니다.

Limitations

There are some limitations when migrating from Azure DevOps to GitHub Actions with GitHub Actions Importer:

  • GitHub Actions Importer requires version 5.0 of the Azure DevOps API, available in either Azure DevOps Services or Azure DevOps Server 2019. Older versions of Azure DevOps Server are not compatible.
  • Tasks that are implicitly added to an Azure DevOps pipeline, such as checking out source code, may be added to a GitHub Actions Importer audit as a GUID name. To find the friendly task name for a GUID, you can use the following URL: https://dev.azure.com/:organization/_apis/distributedtask/tasks/:guid.

Manual tasks

Certain Azure DevOps constructs must be migrated manually from Azure DevOps into GitHub Actions configurations. These include:

  • Organization, repository, and environment secrets
  • Service connections such as OIDC Connect, GitHub Apps, and personal access tokens
  • Unknown tasks
  • Self-hosted agents
  • Environments
  • Pre-deployment approvals

For more information on manual migrations, see Migrating from Azure Pipelines to GitHub Actions.

Unsupported tasks

GitHub Actions Importer does not support migrating the following tasks:

  • Pre-deployment gates
  • Post-deployment gates
  • Post-deployment approvals
  • Some resource triggers

Installing the GitHub Actions Importer CLI extension

  1. GitHub Actions Importer CLI 확장을 설치합니다.

    Bash
    gh extension install github/gh-actions-importer

  2. 다음 확장이 설치되어 있는지 확인:

    $ 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 Azure DevOps and GitHub.

  1. Create a GitHub personal access token (classic). For more information, see 개인용 액세스 토큰 관리.

    Your token must have the workflow scope.

    After creating the token, copy it and save it in a safe location for later use.

  2. Create an Azure DevOps personal access token. For more information, see Use personal access tokens in the Azure DevOps documentation. The token must have the following scopes:

    • Agents Pool: Read
    • Build: Read
    • Code: Read
    • Release: Read
    • Service Connections: Read
    • Task Groups: Read
    • Variable Groups: Read

    After creating the token, copy it and save it in a safe location for later use.

  3. 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 Azure DevOps, 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", enter the URL for GitHub Enterprise Server 인스턴스, and press Enter.
    • For "Personal access token for Azure DevOps", enter the value for the Azure DevOps personal access token that you created earlier, and press Enter.
    • For "Base url of the Azure DevOps instance", press Enter to accept the default value (https://dev.azure.com).
    • For "Azure DevOps organization name", enter the name for your Azure DevOps organization, and press Enter.
    • For "Azure DevOps project name", enter the name for your Azure DevOps project, and press Enter.

    An example of the configure command is shown below:

    $ gh actions-importer configure
✔ Which CI providers are you configuring?: Azure DevOps
Enter the following values (leave empty to omit):
✔ Personal access token for GitHub: ***************
✔ Base url of the GitHub instance: https://github.com
✔ Personal access token for Azure DevOps: ***************
✔ Base url of the Azure DevOps instance: https://dev.azure.com
✔ Azure DevOps organization name: :organization
✔ Azure DevOps project name: :project
Environment variables successfully updated.

  4. In your terminal, run the GitHub Actions Importer update CLI command to connect to the 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 Azure DevOps

You can use the audit command to get a high-level view of all projects in an Azure DevOps organization.

The audit command performs the following steps:

  1. Fetches all of the projects defined in an Azure DevOps organization.
  2. Converts each pipeline to its equivalent GitHub Actions workflow.
  3. Generates a report that summarizes how complete and complex of a migration is possible with GitHub Actions Importer.

Running the audit command

To perform an audit of an Azure DevOps organization, run the following command in your terminal:

gh actions-importer audit azure-devops --output-dir tmp/audit

Forecast potential GitHub Actions usage

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

Running the forecast command

To perform a forecast of potential GitHub Actions usage, run the following command in your terminal. By default, GitHub Actions Importer includes the previous seven days in the forecast report.

gh actions-importer forecast azure-devops --output-dir tmp/forecast_reports

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 Azure DevOps. 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

You can use the dry-run command to convert an Azure DevOps 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.

GitHub Actions Importer이(가) 알 수 없는 빌드 단계 또는 부분적으로 성공한 파이프라인과 같이 자동으로 변환할 수 없는 항목이 있는 경우 변환 프로세스를 추가로 사용자 지정하는 사용자 지정 변환기를 만들 수 있습니다. 자세한 내용은 Extending GitHub Actions Importer with custom transformers을(를) 참조하세요.

Running the dry-run command for a build pipeline

To perform a dry run of migrating your Azure DevOps build pipeline to GitHub Actions, run the following command in your terminal, replacing pipeline_id with the ID of the pipeline you are converting.

gh actions-importer dry-run azure-devops pipeline --pipeline-id :pipeline_id --output-dir tmp/dry-run

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

Running the dry-run command for a release pipeline

To perform a dry run of migrating your Azure DevOps release pipeline to GitHub Actions, run the following command in your terminal, replacing pipeline_id with the ID of the pipeline you are converting.

gh actions-importer dry-run azure-devops release --pipeline-id :pipeline_id --output-dir tmp/dry-run

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

Perform a production migration

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

Running the migrate command for a build pipeline

To migrate an Azure DevOps build pipeline to GitHub Actions, run the following command in your terminal, replacing the target-url value with the URL for your GitHub repository, and pipeline_id with the ID of the pipeline you are converting.

gh actions-importer migrate azure-devops pipeline --pipeline-id :pipeline_id --target-url https://github.com/octo-org/octo-repo --output-dir tmp/migrate

The command's output includes the URL of 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 azure-devops pipeline --target-url https://github.com/octo-org/octo-repo --output-dir tmp/migrate --azure-devops-project my-azure-devops-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'

Running the migrate command for a release pipeline

To migrate an Azure DevOps release pipeline to GitHub Actions, run the following command in your terminal, replacing the target-url value with the URL for your GitHub repository, and pipeline_id with the ID of the pipeline you are converting.

gh actions-importer migrate azure-devops release --pipeline-id :pipeline_id --target-url https://github.com/octo-org/octo-repo --output-dir tmp/migrate

The command's output includes the URL of 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 azure-devops release --target-url https://github.com/octo-org/octo-repo --output-dir tmp/migrate --azure-devops-project my-azure-devops-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'

끌어오기 요청 검사하기

migrate 명령의 성공적인 실행의 출력에는 변환된 워크플로를 리포지토리에 추가하는 새 끌어오기 요청에 대한 링크가 포함되어 있습니다.

끌어오기 요청의 몇 가지 중요 요소는 다음과 같습니다.

  • 끌어오기 요청 설명에서 수동으로 완료해야 하는 단계를 나열하는 섹션은 파이프라인을 GitHub Actions로 마이그레이션을 완료할 수 있습니다. 예를 들어, 이 섹션에서는 워크플로에 사용되는 비밀을 만들도록 지시할 수 있습니다.
  • 변환된 워크플로 파일입니다. 끌어오기 요청에서 Files changed 탭을 선택하여 GitHub 리포지토리에 추가될 워크플로 파일을 봅니다.

끌어오기 요청 검사를 마치면 병합하여 워크플로를 GitHub 리포지토리에 추가할 수 있습니다.

Reference

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

Configuration environment variables

GitHub Actions Importer은(는) 인증 구성에 환경 변수를 사용합니다. 이러한 변수는 configure 명령을 사용하여 구성 프로세스를 따르면 설정됩니다. 자세한 정보는 자격 증명 구성 섹션을 참조하세요.

GitHub Actions Importer uses the following environment variables to connect to your Azure DevOps 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).
  • AZURE_DEVOPS_ACCESS_TOKEN: The personal access token used to authenticate with your Azure DevOps instance. This token requires the following scopes:
    • Build: Read
    • Agent Pools: Read
    • Code: Read
    • Release: Read
    • Service Connections: Read
    • Task Groups: Read
    • Variable Groups: Read
  • AZURE_DEVOPS_PROJECT: The project name or GUID to use when migrating a pipeline. If you'd like to perform an audit on all projects, this is optional.
  • AZURE_DEVOPS_ORGANIZATION: The organization name of your Azure DevOps instance.
  • AZURE_DEVOPS_INSTANCE_URL: The URL to the Azure DevOps instance, such as https://dev.azure.com.

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

Optional arguments

GitHub Actions Importer 하위 명령과 함께 사용하여 마이그레이션을 사용자 지정할 수 있는 선택적 인수가 있습니다.

--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 azure-devops pipeline --output-dir ./output/ --source-file-path ./path/to/azure_devops/pipeline.yml

--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 or composite action should be migrated to.

Audit example

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

gh actions-importer audit azure-devops pipeline --output-dir ./output/ --config-file-path ./path/to/azure_devops/config.yml

To audit an Azure DevOps instance using a configuration file, the configuration file must be in the following format and each repository_slug must be unique:

source_files:
  - repository_slug: azdo-project/1
    path: file.yml
  - repository_slug: azdo-project/2
    paths: path.yml

You can generate the repository_slug for a pipeline by combining the Azure DevOps organization name, project name, and the pipeline ID. For example, my-organization-name/my-project-name/42.

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 --azure-devops-organization and --azure-devops-project option. The path is then used to pull the specified source file.

gh actions-importer dry-run azure-devops pipeline --output-dir ./output/ --config-file-path ./path/to/azure_devops/config.yml
Specify the repository of converted reusable workflows and composite actions

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

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

gh actions-importer audit azure-devops --output-dir ./output/

The output of this command will contain a file named config.yml that contains a list of all the reusable workflows and 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

composite_actions:
  - name: my-composite-action.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 azure-devops pipeline --config-file-path config.yml --target-url https://github.com/my-org/my-repo

Templates

You can transform Azure DevOps templates with GitHub Actions Importer.

Limitations

GitHub Actions Importer is able to transform Azure DevOps templates with some limitations.

  • Azure DevOps templates used under the stages, deployments, and jobs keys are converted into reusable workflows in GitHub Actions. For more information, see Reusing workflows.
  • Azure DevOps templates used under the steps key are converted into composite actions. For more information, see Creating a composite action.
  • If you currently have job templates that reference other job templates, GitHub Actions Importer converts the templates into reusable workflows. Because reusable workflows cannot reference other reusable workflows, this is invalid syntax in GitHub Actions. You must manually correct nested reusable workflows.
  • If a template references an external Azure DevOps organization or GitHub repository, you must use the --credentials-file option to provide credentials to access this template. For more information, see 추가 인수 및 설정.
  • You can dynamically generate YAML using each expressions with the following caveats:
    • Nested each blocks are not supported and cause the parent each block to be unsupported.
    • each and contained if conditions are evaluated at transformation time, because GitHub Actions does not support this style of insertion.
    • elseif blocks are unsupported. If this functionality is required, you must manually correct them.
    • Nested if blocks are supported, but if/elseif/else blocks nested under an if condition are not.
    • if blocks that use predefined Azure DevOps variables are not supported.
