GH-200 Exam Dumps - GitHub Actions Exam

To use a starter workflow provided by your organization, you need to go to the Actions tab in the repository and select New workflow. This option allows you to either create a new workflow or select from a list of available workflow templates, including starter workflows provided by your organization.

Workflow commands are special commands that allow you to interact with the runner, set environment variables, output values, add debug messages, and perform other tasks within the workflow. These commands are used to modify the environment or influence the behavior of the GitHub Actions runner.

Creating a separate repository for each custom action allows you to manage the versioning independently for each action. This approach provides flexibility, as each action can be updated, tested, and versioned separately, avoiding potential conflicts or dependencies between different actions.

Dockerfile: The Dockerfile is required for Docker container actions. It defines the environment for the action, specifying the base image, dependencies, and any commands to set up the action’s runtime inside the container.

action.yml: The action.yml file is required for all GitHub Actions, including Docker container actions. It contains metadata about the action, including the inputs, outputs, and the runtime environment (which in this case is Docker, defined under runs.using).

A Docker container action is ideal for custom actions that require specific environments or dependencies, such as Python. By creating a Docker container, you can define the environment with the necessary Python version and dependencies, and your Python code can run inside that container.

The publish-npm job includes the JS-DevTools/npm-publish action, which is used to publish an npm package to an npm registry.

The publish-npm job has the needs: build directive, meaning it will only run after the build job successfully completes.

Setting a debug message using ::debug:: command sends a message to the logs, helping with troubleshooting and providing insight into the workflow run.

Setting output parameters using ::set-output sends data from a job step to subsequent steps or jobs, which can be used later in the workflow.

The correct minimal syntax for declaring an output in GitHub Actions is by using the foo key under outputs, and associating it with a value (in this case, Some value). This is the simplest form to define an output in a workflow or action.
