name: Sample-Hello_World on: workflow_dispatch env: TEST_VARIABLE: "Simon G test variable" jobs: SampleJob: runs-on: group: CBS-Bank-Runners steps: - name: Sample run: | echo "Hello World" echo "The date is $(date -I)" echo "The sample variable is: $TEST_VARIABLE" echo "Github Actions can also insert variables like this: ${{ env.TEST_VARIABLE }}"

This code is a GitHub Actions workflow configuration file written in YAML. Here's what it does:

  1. Workflow Name:

    • "Sample-Hello_World" is the name of the workflow.

  2. Trigger:

    • The workflow is triggered manually via the workflow_dispatch event. This means it won't automatically execute unless someone explicitly starts it through GitHub Actions.

  3. Environment Variable:

    • Defines an environment variable named TEST_VARIABLE with the value "Simon G test variable".

  4. Job Definition:

    • A single job named SampleJob is defined.
    • It runs on a specific runner group (CBS-Bank-Runners), which is likely a self-hosted runner group.

  5. Job Steps:

    • A single step is executed in the SampleJob.
    • The step:
      • Prints "Hello World" to the console.
      • Prints the current date in ISO 8601 format (date -I).
      • Prints the environment variable TEST_VARIABLE using shell syntax ($TEST_VARIABLE).
      • Prints the same environment variable using GitHub Actions' specific syntax for referencing environment variables (${{ env.TEST_VARIABLE }}).

Summary:

This workflow can be triggered manually. When triggered, it runs on the CBS-Bank-Runners group and executes a script that:

  • Prints a "Hello World" message.
  • Displays the current date.
  • Demonstrates two ways of outputting an environment variable value (TEST_VARIABLE).
