GH-200 Exam Dumps : GitHub Actions Exam

A composite action allows you to bundle multiple steps into a single reusable action within a workflow. It is composed of multiple run steps or other actions and can be reused across workflows, making it the perfect choice for bundling a series of steps.

GITHUB_WORKSPACE is a default environment variable in GitHub Actions that points to the directory on the runner where your repository is checked out. This variable allows you to access files within your repository during the workflow.

Actions can be stored in a separate public repository and referenced in workflows by specifying the repository and action name.

Actions can also be stored in the same repository as the workflow and referenced directly by their path (e.g., ./.github/actions/my-action).

Actions can be packaged as Docker container images and published to Docker Hub. These can then be referenced in workflows by specifying the Docker image.
