Checkout V2 beta

This action checks-out your repository under $GITHUB_WORKSPACE, so your workflow can access it.

By default, the repository that triggered the workflow is checked-out, for the ref/SHA that triggered the event.

Refer here to learn which commit $GITHUB_SHA points to for different events.

What's new

• Improved fetch performance
  • The default behavior now fetches only the commit being checked-out
• Script authenticated git commands
  • Persists the input token in the local git config
  • Enables your scripts to run authenticated git commands
  • Post-job cleanup removes the token
  • Opt out by setting the input persist-credentials: false
• Creates a local branch
  • No longer detached HEAD when checking out a branch
  • A local branch is created with the corresponding upstream branch set
• Improved layout
  • The input path is always relative to $GITHUB_WORKSPACE
  • Aligns better with container actions, where $GITHUB_WORKSPACE gets mapped in
• Fallback to REST API download
  • When Git 2.18 or higher is not in the PATH, the REST API will be used to download the files
• Removed input submodules

Usage

- uses: actions/checkout@v2-beta
  with:
    # Repository name with owner. For example, actions/checkout
    # Default: ${{ github.repository }}
    repository: ''

    # The branch, tag or SHA to checkout. When checking out the repository that
    # triggered a workflow, this defaults to the reference or SHA for that event.
    # Otherwise, defaults to `master`.
    ref: ''

    # Auth token used to fetch the repository. The token is stored in the local git
    # config, which enables your scripts to run authenticated git commands. The
    # post-job step removes the token from the git config.
    # Default: ${{ github.token }}
    token: ''

    # Whether to persist the token in the git config
    # Default: true
    persist-credentials: ''

    # Relative path under $GITHUB_WORKSPACE to place the repository
    path: ''

    # Whether to execute `git clean -ffdx && git reset --hard HEAD` before fetching
    # Default: true
    clean: ''

    # Number of commits to fetch. 0 indicates all history.
    # Default: 1
    fetch-depth: ''

    # Whether to download Git-LFS files
    # Default: false
    lfs: ''

Checkout a different branch

- uses: actions/checkout@v2-beta
  with:
    ref: some-branch

Checkout a different, private repository

- uses: actions/checkout@v2-beta
  with:
    repository: myAccount/myRepository
    ref: refs/heads/master
    token: ${{ secrets.GitHub_PAT }} # `GitHub_PAT` is a secret that contains your PAT

• ${{ github.token }} is scoped to the current repository, so if you want to checkout another repository that is private you will need to provide your own PAT.

Checkout the HEAD commit of a PR, rather than the merge commit

- uses: actions/checkout@v2-beta
  with:
    ref: ${{ github.event.pull_request.head.sha }}
