Define multiple workflows in one yaml file

[alexbde]

I tried to define multiple workflows on one yaml file using yaml document separator --- and it did not work. Is this by intention or did I miss something?

Example:

name: First Workflow
on: push
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: test
      run: echo "Hello, world."
---
name: Second Workflow
on: push
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: test
      run: echo "Hello, again."

Expected: two workflows are defined (called “First Workflow” and “Second Workflow”)

Actually: Only first workflow is defined (called “First Workflow”), second workflow is ignored

At the moment, that’s not supported.  You’ll need a single workflow per yaml file.

Okay. Too bad, but thank you for your quick answer :slight_smile:

Hi, are there any plans to support this feature in the future ?

Agree that this would make for cleaner code, especially when doing things like this!

Any update on this feature? Just tried to do the same thing and got a parsing error. Not sure why this would be an issue when it is native yaml functionality, and certainly would lead to much cleaner code!

Any update on this feature? Still not working.

ping! this is useful/important (unless I am missing an alternative way) when defining a shared set of workflows and wanting to include them all in a bunch of repos in same org

One use case where this could be useful is for workflows that take user input that needs to be sanitised before being used.

Content of .github/workflows/multi-workflow.yml

---
name: Sanitise User Input
on:
  workflow_dispatch:
    inputs:
      unsafe-user-input:
        required: true
        type: string

jobs:
  sanitise-input:
    runs-on: ubuntu-latest
    outputs:
      safer-user-input: ${{ steps.get-safer-user-input.outputs.SAFER_USER_INPUT }}
    steps:
    - name: Sanitise user input
      id: get-safer-user-input
      env: 
        UNSAFE_USER_INPUT: ${{ inputs.unsafe-user-input }}
      run: |
        # Code to sanitise UNSAFE_USER_INPUT and store it in SAFER_USER_INPUT
        ...
        echo "SAFER_USER_INPUT=$SAFER_USER_INPUT" >> $GITHUB_OUTPUT
  run-payload:
    needs: [sanitise-input]
    uses: .github/workflows/multi-workflow.yml
    with:
      safer-user-input: ${{ needs.sanitise-input.outputs.safer-user-input }}

name: Run Workflow Using Sanitised User Input
on:
  workflow-call:
    inputs:
      safer-user-input:
        required: true
        type: string
