# Deploy All Components

Run a workflow across every component instance in your stacks. Generate the job matrix from Atmos instead of maintaining a separate inventory in your workflow.

Use [Setup Atmos](/integrations/github-actions/setup-atmos) to pin the Atmos container version, enable [native CI reporting](/ci#quick-start), and configure [authentication and permissions](/integrations/github-actions/authentication) for your repository.

## Workflow

Fan out across **every** instance defined in your stacks using `atmos list instances --format=matrix`. Use this for full deploys, drift sweeps across the whole estate, or initial bootstraps. Like `describe affected`, it auto-routes to `$GITHUB_OUTPUT` when CI is enabled.

**File:** `.github/workflows/deploy-all.yml`
