如何在 Github 操作中运行多个节点应用程序？

Question

This is my actions

# This is a basic workflow to help you get started with Actions

name: CI/CD Akper Bina Insan - Live

on:
  push:
    branches: [ master ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x]
    steps:
    - uses: actions/checkout@v2
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v2
      with:
        node-version: ${{ matrix.node-version }}
    - name: Install Yarn
      run: npm install -g yarn
    - name: Build UI - Akper Bina Insan
      working-directory: ./ui
      run: yarn && yarn build && yarn start
    - name: Build Backend Service - Akper Bina Insan
      working-directory: ./be
      run: yarn && yarn build && yarn prod

After it finished with the first run, it don't go continue with the second run. Even though the server is ready. I waited for 5 minutes then I stopped since I don't want to waste time.

How can I make it run for the second one?

Answer 1

GitHub actions are a tool for CI/CD and not for hosting (running) your application.

In the given workflows, you build an then run your UI application. The run command is a blocking process - eg your workflow will remain blocked because you have started your UI application. You should not do that in workflows.

Use GitHub Action for build and test, but not for hosting.

Answer 2

Adding an ending & to the node command solved this for my use-case

run: yarn && yarn build && yarn start &

or

run: | 
  yarn
  yarn build
  yarn start &

Using & in the end of a command, the shell executes the command in the background in a subshell, therefore running the first yarn start won't be blocking your next step in the workflow.
