⚠️ ⚠️ ⚠️ ⚠️ NOW DO SOME STUFF ⚠️ ⚠️ ⚠️ ⚠️

• Please clone this repository and then create your own branch ws-myname
• Then modify the simple my-first-action.yml to be able to run it on every push on your specific branch only.
• Add an input to be able to pass the version that you want to trigger (a text input named version).

Actions

Basic job definition

jobs:
  my_first_job:
    name: My first job
  my_second_job:
    name: My second job

Job Dependencies

jobs:
  job1:
  job2:
    needs: job1
  job3:
    needs: [job1, job2]

And now where the magic happens

- uses: actions/setup-node@v2
  with:
    node-version: '14'

⚠️ ⚠️ ⚠️ ⚠️ NOW DO SOME STUFF ⚠️ ⚠️ ⚠️ ⚠️

• By reusing the workflow my-first-action.yml modify it to add two step, one for running a build and one for a run.
• Check on a new github action that you can use to modify json file (JQ) and use it to update the package version version with the one you give as input.
• Create two jobs, one for build, one for run with a dependency

If you have the time :

• edit the my-scheduled-action.yml workflow to add a scheduled run on the other workflow

Help

To be able to do this you will need to check this specific things :

• Workflow triggering :

    steps:
      - uses: ./.github/workflows/my-action
        with:
          username: ${{ inputs.username }}

Scheduled trigger :

on:
schedule:
# * is a special character in YAML so you have to quote this string
- cron:  '30 5,17 * * *'

NOTE: Scheduled workflow are only trigger for main, you will need two things to make it works on your branch:

• Trigger your workflow on the main branch
• specificly checkout your branch at the beginning of the pipeline if you want to execute it.
