Workflow YAML Basic Structure Explanation

name: Github action workflow name

on:
  push: # Run this workflow every time a new commit pushed to the repository
  pull_request:  # Run this workflow every time a new pull request is opened to the repository
  scheduled: # Run this workflow as a cron job
    - cron: "0 0 * * MON-FRI"
  workflow_dispatch: # Run this workflow on demand (manually)

jobs: # All workflows need at list one job

  job-key: #First job
    name: Job Name
    runs-on: ubuntu-latest # Set the type of machine the workflow will run on
    steps: # Each job can be divided in many steps

      - name: Checkout code # Step name
        uses: actions/checkout@v2 # Action used on the step

      - name: Run Super-Linter # Another step name
        uses: github/super-linter@v3  # Action used on the step
        env:  # Environment variables used on the step
          DEFAULT_BRANCH: main
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

      - name: Run specific commands # Another step name
        run: |
          ls -lha
          echo "This is a shell command"

Examples

This workflow uses CRON to run some basic commands.

This workflow uses CRON to run some basic commands using repository secrets.

This workflow uses CRON to execute a specific script run.py located on the repository.

This workflow uses CRON to dispatch an event to the ritchie-formulas-scheduler-demo repository.

This workflow uses CRON with a docker container where Ritchie CLI and Golang are installed, then check Ritchie CLI and Golang versions through commands.

This workflow uses CRON and a docker image foundeo/minibox:latest. It also specify an entrypoint (the command to run inside the container) and args (command line arguments to pass to the command specified in entrypoint). It is possible to omit the entrypoint if the container already species the entrypoint you want to use.

This workflow will run an Action each time a PUSH event occurs on the repository. This specific action runs a Ritchie CLI formula.

This workflow illustrates how to use outputs between jobs with the needs context to check tags and manage them to perfom some operation according to their name.

This workflow illustrates how to create a new Pull Request based on a branch name after a push event.

This workflow illustrates how to add a comment on a new Pull Request based on the github actor name after a PR event.

This workflow illustrates how to call a webhook on each release extracting the release tag.

This workflow illustrates how to close a Pull Request automatically if it updates on file that shouldn't be modified.

This workflow illustrates how to perform a specific action when approving a Pull request if it contains a specific label.

This workflow illustrates how to implement a reusable workflow.

This workflow illustrates how to use and call a reusable workflow (cf workflow 33 above).

This workflow illustrates how to extract and use the user email and username from the commit using github config log commands.

This workflow illustrates how to use a local action file in one (or multiple workflows) and extract its outputs to perform other operations.

This workflow illustrates how to use matrix as well as expressions with continue-on-error and if conditionnal fields.

This workflow illustrates how to get the related PR number to a push event.

PR event and Related PUSH event

This workflows illustrate how to extract the tag version when a specific branch is created (e.g: release-1.2.3), and how to invoke another workflow through a disptach event sending this tag as input.

This workflow illustrates how to commit files from the current repo to another repo.

This workflow illustrates how to trigger a workflow on different event but NOT on tag.

This workflow illustrates how to check if a PR is opened from a FORK repository or not.

This workflow illustrates how to list all files from a specific extension (here, .yaml or .yml).

This workflow illustrates how to list all env variables set in the runner.

- AS EXPECTED

This workflow illustrates how to force a workflow failure if a condition isn't met.

- DEPRECATED

This workflow illustrates how to wait for other workflows completion before executing some operation (using reusable workflows).

This workflow illustrates how to rename a file according to the github ref name (branch or tag name).

This workflow illustrates how to simply create a tag in a job.

This workflow illustrates how to use concurrency to avoid the same workflow to run in parallel for different push to the same branch (for example to limit Github actions runner usage in private repo).

This workflow illustrates how to print secrets values on a workflow run. To harden the security of your github actions, have a look at this guide on the Github Official Documentation.
