Trigger a job after the success of previous job

Question

I'm looking for guidance on modifying my GitHub Actions workflow to trigger a job build automatically after the successful completion of a "validate" job. Currently, the workflow looks like the following:

validate.yml

name: Validate

on:
  push:
    branches: [ "DEVELOP" ]
    tags:
      - v**
  pull_request:
    branches: [ "DEVELOP" ]
    tags:
      - v**

jobs:
  validate:
    runs-on: ubuntu-latest
    ....

build.yml

name: Build

on:
  workflow_run:
    workflows:
      - Validate
    types:
      - completed
  workflow_dispatch:



jobs:
  build:
    name: Push to Docker image to GitHub
    runs-on: ubuntu-latest
    .....

Answer 1

I found the answer in the Git documents from here. I want the 'build' job to run after the 'validate' job successfully completes. Therefore, in the 'build' job, I need to check if the 'preview' job was successful before starting.

Answer:

on:
  workflow_run:
    workflows:
      - Validate
    types:
      - completed

jobs:
  build:
    name: Push to Docker image to GitHub
    runs-on: ubuntu-latest
    if: ${{ github.event.workflow_run.conclusion == 'success' }}
....
