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 to pin the Atmos container version, enable native CI reporting, and configure authentication and permissions 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.
