Migrating from Azure DevOps with GitHub Actions Importer

Legal notice

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.

• An environment where you can run Linux-based containers, and can install the necessary tools.

  • Docker is installed and running.
  • GitHub CLI is installed.

  Note: The GitHub Actions Importer container and CLI do not need to be installed on the same server as your CI platform.

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. Install the GitHub Actions Importer CLI extension:

   Bash

   gh extension install github/gh-actions-importer
   

2. Verify that the extension is installed:

   $ gh actions-importer -h
   Options:

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. For more information, see "Managing your personal access tokens."

   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 that you created earlier, and press Enter.

   • For "Base url of the GitHub instance", enter the URL for your GitHub Enterprise Server instance, 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

Inspecting the audit results

The files in the specified output directory contain the results of the audit. See the audit_summary.md file for a summary of the audit results.

The audit summary has the following sections.

Pipelines

The "Pipelines" section contains a high-level statistics regarding the conversion rate done by GitHub Actions Importer.

Listed below are some key terms that can appear in the "Pipelines" section:

• Successful pipelines had 100% of the pipeline constructs and individual items converted automatically to their GitHub Actions equivalent.
• Partially successful pipelines had all of the pipeline constructs converted, however, there were some individual items that were not converted automatically to their GitHub Actions equivalent.
• Unsupported pipelines are definition types that are not supported by GitHub Actions Importer.
• Failed pipelines encountered a fatal error when being converted. This can occur for one of three reasons:
  • The pipeline was misconfigured and not valid in Bamboo.
  • GitHub Actions Importer encountered an internal error when converting it.
  • There was an unsuccessful network response that caused the pipeline to be inaccessible, which is often due to invalid credentials.

Build steps

The "Build steps" section contains an overview of individual build steps that are used across all pipelines, and how many were automatically converted by GitHub Actions Importer.

Listed below are some key terms that can appear in the "Build steps" section:

• A known build step is a step that was automatically converted to an equivalent action.
• An unknown build step is a step that was not automatically converted to an equivalent action.
• An unsupported build step is a step that is either:
  • Fundamentally not supported by GitHub Actions.
  • Configured in a way that is incompatible with GitHub Actions.
• An action is a list of the actions that were used in the converted workflows. This can be important for:
  • If you use GitHub Enterprise Server, gathering the list of actions to sync to your instance.
  • Defining an organization-level allowlist of actions that are used. This list of actions is a comprehensive list of actions that your security or compliance teams may need to review.

Manual tasks

The "Manual tasks" section contains an overview of tasks that GitHub Actions Importer is not able to complete automatically, and that you must complete manually.

Listed below are some key terms that can appear in the "Manual tasks" section:

• A secret is a repository or organization-level secret that is used in the converted pipelines. These secrets must be created manually in GitHub Actions for these pipelines to function properly. For more information, see "Encrypted secrets."
• A self-hosted runner refers to a label of a runner that is referenced in a converted pipeline that is not a GitHub-hosted runner. You will need to manually define these runners for these pipelines to function properly.

Files

The final section of the audit report provides a manifest of all the files that were written to disk during the audit.

Each pipeline file has a variety of files included in the audit, including:

• The original pipeline as it was defined in GitHub.
• Any network responses used to convert the pipeline.
• The converted workflow file.
• Stack traces that can be used to troubleshoot a failed pipeline conversion.

Additionally, the workflow_usage.csv file contains a comma-separated list of all actions, secrets, and runners that are used by each successfully converted pipeline. This can be useful for determining which workflows use which actions, secrets, or runners, and can be useful for performing security reviews.

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.

If there is anything that GitHub Actions Importer was not able to convert automatically, such as unknown build steps or a partially successful pipeline, you might want to create custom transformers to further customize the conversion process. For more information, see "Extending GitHub Actions Importer with custom transformers."

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'

Inspecting the pull request

The output from a successful run of the migrate command contains a link to the new pull request that adds the converted workflow to your repository.

Some important elements of the pull request include:

• In the pull request description, a section called Manual steps, which lists steps that you must manually complete before you can finish migrating your pipelines to GitHub Actions. For example, this section might tell you to create any secrets used in your workflows.
• The converted workflows file. Select the Files changed tab in the pull request to view the workflow file that will be added to your GitHub Enterprise Server repository.

When you are finished inspecting the pull request, you can merge it to add the workflow to your GitHub Enterprise Server repository.

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 Importer uses environment variables for its authentication configuration. These variables are set when following the configuration process using the configure command. For more information, see the "Configure credentials for GitHub Actions Importer" section.

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

• GITHUB_ACCESS_TOKEN: The personal access token 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

There are optional arguments you can use with the GitHub Actions Importer subcommands to customize your migration.

--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 --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 "Supplemental arguments and settings."
• 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.
