Limitations

Example reusable workflow

name: Reusable workflow example

  workflow_call:
    inputs:
      username:
        required: true
        type: string
    secrets:
      token:
        required: true

jobs:
  example_job:
    name: Pass input and secrets to my-action
    runs-on: ubuntu-latest
    steps:
      - uses: ./.github/actions/my-action@v1
        with:
          username: ${{ inputs.username }}
          token: ${{ secrets.token }}      

Calling a reusable workflow

name: Call a reusable workflow

  pull_request:
    branches:
      - main

jobs:
  call-workflow:
    uses: octo-org/example-repo/.github/workflows/workflow-A.yml@v1

  call-workflow-passing-data:

    with:
      username: mona
    secrets:
      token: ${{ secrets.TOKEN }}

Using outputs from a reusable workflow

name: Reusable workflow

on:
  workflow_call:
    # Map the workflow outputs to job outputs
    outputs:
      firstword:
        description: "The first output string"
        value: ${{ jobs.example_job.outputs.output1 }}
      secondword:
        description: "The second output string"
        value: ${{ jobs.example_job.outputs.output2 }}  
  
jobs:
  example_job:
    name: Generate output
    runs-on: ubuntu-latest   
    # Map the job outputs to step outputs
    outputs:
      output1: ${{ steps.step1.outputs.firstword }}
      output2: ${{ steps.step2.outputs.secondword }}
    steps:
      - id: step1
        run: echo "::set-output name=firstword::hello"
      - id: step2
        run: echo "::set-output name=secondword::world"
