Keeping your actions up to date with Dependabot

You can use Dependabot to keep the actions you use updated to the latest versions.

About Dependabotバージョンアップデート for actions

Actions are often updated with bug fixes and new features to make automated processes more reliable, faster, and safer. When you enable Dependabotバージョンアップデート for GitHub Actions, Dependabot will help ensure that references to actions in a repository's workflow.yml file are kept up to date. For each action in the file, Dependabot checks the action's reference (typically a version number or commit identifier associated with the action) against the latest version. If a more recent version of the action is available, Dependabot will send you a pull request that updates the reference in the workflow file to the latest version. For more information about Dependabotバージョンアップデート, see "About Dependabotバージョンアップデート." For more information about configuring workflows for GitHub Actions, see "Learn GitHub Actions."

ノート: DependabotのPull Requestによってトリガーされたワークフローの実行は、フォークされたリポジトリからのように実行されるので、読み取りのみのGITHUB_TOKENを使用します。 それらのワークフローの実行は、シークレットにはアクセスできません。 これらのワークフローをセキュアに保つための方針については、「GitHub Actionsとワークフローをセキュアに保つ: pwnリクエストの回避」を参照してください。

Enabling Dependabotバージョンアップデート for actions

You can configure Dependabotバージョンアップデート to maintain your actions as well as the libraries and packages you depend on.

  1. If you have already enabled Dependabotバージョンアップデート for other ecosystems or package managers, simply open the existing dependabot.yml file. Otherwise, create a dependabot.yml configuration file in the .github directory of your repository. For more information, see "Configuring Dependabot version updates."
  2. Specify "github-actions" as a package-ecosystem to monitor.
  3. Set the directory to "/" to check for workflow files in .github/workflows.
  4. Set a schedule.interval to specify how often to check for new versions.
  5. リポジトリ内の .github ディレクトリにある dependabot.yml 設定ファイルを確認します。 If you have edited an existing file, save your changes.

You can also enable Dependabotバージョンアップデート on forks. For more information, see "Configuring Dependabot version updates."

Example dependabot.yml file for GitHub Actions

The example dependabot.yml file below configures version updates for GitHub Actions. The directory must be set to "/" to check for workflow files in .github/workflows. The schedule.interval is set to "daily". After this file has been checked in or updated, Dependabot checks for new versions of your actions. Dependabot will raise pull requests for version updates for any outdated actions that it finds. After the initial version updates, Dependabot will continue to check for outdated versions of actions once a day.

# Set update schedule for GitHub Actions

version: 2
updates:

  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      # Check for updates to GitHub Actions every weekday
      interval: "daily"
