Question

Your team maintains a Docker container action used across several repositories. To speed up job startup, you want the action to pull a pre-built image from GitHub Container Registry (ghcr.io) instead of building the Dockerfile on every run. Which value should you set for the `runs.image` key in the action's action.yml?

Answer

`registry://ghcr.io/my-org/my-action:1.2.3`
