Manual Run

manual.yaml:

name: Manual Run
run-name: Test
on:
  workflow_dispatch:
    inputs:
      LABEL:
        required: true
        type: string
        description: label

jobs:
  run:
    runs-on: ${{ inputs.LABEL }}
    steps:
      - run: hostname

Basic Workflow

name: GitHub Actions Demo
run-name: ${{ github.actor }} is testing out GitHub Actions 🚀
on: [push]
jobs:
  Explore-GitHub-Actions:
    runs-on: ubuntu-latest
    steps:
      - run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event."
      - run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!"
      - run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}."
      - name: Check out repository code
        uses: actions/checkout@v3
      - run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner."
      - run: echo "🖥️ The workflow is now ready to test your code on the runner."
      - name: List files in the repository
        run: |
          ls ${{ github.workspace }}
      - run: echo "🍏 This job's status is ${{ job.status }}."

Using Job Output

jobs:
  job1:
    runs-on: ubuntu-latest
    # Map a step output to a job output
    outputs:
      output1: ${{ steps.step1.outputs.test }}
      output2: ${{ steps.step2.outputs.test }}
    steps:
      - id: step1
        run: echo "test=hello" >> "$GITHUB_OUTPUT"
      - id: step2
        run: echo "test=world" >> "$GITHUB_OUTPUT"
  job2:
    runs-on: ubuntu-latest
    needs: job1
    steps:
      - env:
          OUTPUT1: ${{needs.job1.outputs.output1}}
          OUTPUT2: ${{needs.job1.outputs.output2}}
        run: echo "$OUTPUT1 $OUTPUT2"

Dynamic Runs-on

jobs:
  run:
    # runs-on: ${{ fromJSON( '["CI"]' ) }}  # This works
    # runs-on: ${{ fromJSON( '["CI", "MORE"]' ) }}  # This works
    runs-on: ${{ fromJSON( inputs.LABELS ) }}  # This works if formatted like: ["CI", "MORE"]
    # runs-on: ${{ inputs.LABELS }}  # this works for single label
    # runs-on: [ CI, MORE ]  # this works

Remotely Trigger Workflow - repository_dispatch

on:
  repository_dispatch:

---

on:
  repository_dispatch:
    types: [some_event_type]


curl -X POST https://api.github.com/repos/OWNER/REPO/dispatches -H "Authorization: Bearer ${GH_TOKEN}" -d '{"event_type":"some_event_type"}'

---

curl -X POST https://api.github.com/repos/ORG/REPO/dispatches -d '{"event_type":"some_event_type"}'
 #  -d or --data, -X or --request
 #  -H "Accept: application/vnd.github.v3+json"
 #  -H "Accept: application/vnd.github+json"
 # You will most likely need to also pass along auth: (unless you are silly and on a publicly executable workflow?)
 # -H "Authorization: Bearer $GITHUB_TOKEN"
curl -L \
 -X POST \
 -H "Accept: application/vnd.github+json" \
 -H "Authorization: Bearer <YOUR-TOKEN>" \
 -H "X-GitHub-Api-Version: 2022-11-28" \
 https://api.github.com/repos/OWNER/REPO/dispatches \
 -d '{"event_type":"on-demand-test","client_payload":{"unit":false,"integration":true}}'

if you want to trigger from some other branch:
 {...,'ref':'other_branch_or_ref'},...}

If you pass this payload through, you can limit the workflow, and access it in the workflow:

{
  "event_type": "test_result",
  "client_payload": {
    "passed": false,
    "message": "Error: timeout"
  }
}

workflow:

on:
  repository_dispatch:
    types: [test_result]

jobs:
  run_if_failure:
    if: ${{ !github.event.client_payload.passed }}
    runs-on: ubuntu-latest
    steps:
      - env:
          MESSAGE: ${{ github.event.client_payload.message }}
        run: echo $MESSAGE
