I have a file

deploy-list.json:

{
    "apiList": [
      "abc",
      "def"    
    ]
}

I would like to run a GitHub action with matrix (parallel) jobs for each of the item in the apiList above.

name: API Build

on: 
  workflow_dispatch:
    inputs:
      branch:
        description: 'Github Release Branch Name'
        required: true
        default: 'release/1.5.3'

  push:
    branches:
    - 'develop'

jobs:

  build-matrix:
    runs-on: ubuntu-latest

    steps:

      - name: Checkout Branch
        uses: actions/checkout@v2
        with:          
          ref: "${{ github.event.inputs.branch }}"

      - name: Set Matrix
        id: set-matrix
        run: echo "::set-output name=api_matrix::$(cat deploy-list.json | jq -c '.apiList')"

    outputs:
      api_matrix: ${{ steps.set-matrix.outputs.api_matrix }}

  build-api:
    environment: PRD
    needs: build-matrix
    runs-on: ubuntu-latest
    strategy:
      matrix:
        api_name: ${{ fromJson(needs.build-matrix.outputs.api_matrix) }}
    steps:
      - name: Checkout Branch
        uses: actions/checkout@v2
        with:
          ref: "${{ github.event.inputs.branch }}"

      - name: Building ${{ matrix.api_name }}
        run: |
          echo ${{ matrix.api_name }}
          # Do something here

Two parallel jobs will be invoked for "abc" and "def" apis making the workflow complete in twice as fast build time. I also using maven caching to speed up the builds even further.
