Git Checkouts - Namespace Documentation

Namespace can speed up your git checkouts by caching a mirror of your git repository. Checkout caching works best when cloning large repositories with many files. If you are also checking out submodules or rely on Git LFS, these are automatically cached, too.

Getting started

When running your GitHub Actions on Namespace runners, cached git checkouts are available directly from the UI.

Enable Git Checkout caching

In your runner profile, enable Git repository checkouts in the caching section.

Configure your workflow

To start using the newly enabled cache in your workflow, replace mentions of actions/checkout with nscloud-checkout-action:

jobs:
  tests:
    runs-on: namespace-profile-integration-tests
    steps:
      - name: Check out my repo
        uses: actions/checkout@v4
        uses: namespacelabs/nscloud-checkout-action@v8
        with:
          path: my-repo
      - run: |
          cd my-repo && git status

Check out the action reference for a full list of supported options.

How it works

Namespace retains a mirror of your git repository on Cache Volumes, making them available on subsequent runs. Cache Volumes are Namespace’s high-performance caching solution that persists data across GitHub Actions runs. Unlike traditional caching solutions that require time-consuming uploads and downloads, Cache Volumes provide instant access to cached data through guaranteed cache locality.
