What are Actions

GitHub Actions are modular, reusable units of automation that you integrate into your workflows to handle tasks such as continuous integration, continuous deployment, and code reviews. Authored by GitHub or community contributors, actions make it easy to share and maintain automation logic across repositories.

Discovering Actions on GitHub Marketplace

Explore the GitHub Marketplace to find hundreds of pre-built actions. Verified badges indicate official partner organizations, while unbadged entries are contributed by the community.

Always review an action’s source code before integrating it. Ensure it handles your repository’s content and secrets safely—never exposes secrets to unintended hosts or logs sensitive data.

Pinning Action Versions

For reliable and predictable workflows, define the action version by tag, branch, or commit SHA:

steps:
  - name: Checkout using a specific tag
    uses: actions/checkout@v3.6.0

  - name: Checkout using the main branch
    uses: actions/checkout@main

  - name: Checkout using a commit SHA
    uses: actions/checkout@a824008085750b8e136effc585c3cd6082bd575f

Strategy	Syntax Example	Pros	Cons
Tag	`actions/checkout@v3.6.0`	Controlled upgrades between versions	Requires manual version updates
Branch	`actions/checkout@main`	Automatically uses the latest code	May introduce breaking changes
Commit SHA	`actions/checkout@a824008085750b8e136effc585c3cd6082bd575f`	Immutable reference for reproducible builds	Harder to benefit from upstream fixes

Tags strike a balance between stability and ease of upgrades. Use SHAs when you need fully reproducible builds.
