Create Pull Request

GitHub Action

try it by documents

name: Create production promotion pull request
on:
  push:
    branches:
      - main
jobs:
  productionPromotion:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
        with:
          ref: production
      - name: Reset promotion branch
        run: |
          git fetch origin main:main
          git reset --hard main
      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v4
        with:
          branch: production-promotion

但是并没有生效，就更换了其他的 ci。

GitHub Pull Request Action

docs

# ./.github/workflows/staging-auto-pr.yaml
name: Staging Auto-PR
on:
  push:
    branches: [staging]

jobs:
  pull-request:
    name: Open PR to main
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        name: checkout

      - uses: repo-sync/pull-request@v2
        name: pull-request
        with:
          destination_branch: main
          pr_title: 'Pulling ${{ github.ref }} into main'
          pr_body: '👑 *An automated PR*'
          pr_reviewer: kingdonb
          pr_draft: true
          github_token: ${{ secrets.GITHUB_TOKEN }}

也即本网站的最终方案
如果提交无变更，则不执行此 job，参看若未改动则不 pr

Tips

github.com slowly 访问慢

通过 ipaddress 来获得github.com、github.global.ssl.fastly.net、codeload.github.com这三个域名的服务器公网IP地址

vim /etc/hosts

添加如下内容

140.82.114.4    github.com
199.232.5.194   github.global.ssl.fastly.net

指定条件运行指定 job

条件判断，多个 job 时，指定某个特定条件下运行某个 job

on:
  # Runs on pushes targeting the default branch
  push:
    branches: ["master"]
  pull_request:
    branches: ["master"]
jobs:
  # Build job
  build:
    # something
  # Deployment job
  deploy:      
    # something
    if: github.event_name == 'push'

若未改动则不 pr

- name: Commit files
  id: commit
  run: |
    git config --local user.email "action@github.com"
    git config --local user.name "GitHub Action"
    git add .
    if git diff --cached --quiet; then  
      echo "No changes to commit"  
      echo "has_changes=false" >> $GITHUB_OUTPUT
    else  
      git commit -m "something" -a
      echo "has_changes=true" >> $GITHUB_OUTPUT
    fi
- name: Create Pull Request
  if: ${{ steps.commit.outputs.has_changes == 'true' }}
  uses: peter-evans/create-pull-request@v6
  with:

    title: "something"

关于 GITHUB_OUTPUT 的使用

- name: test output
  env:
    AUG: ${{steps.commit.outputs.has_changes}}
  run: |
    echo "=========="
    echo "$GITHUB_OUTPUT"
    echo "=========="
    echo "${{steps.commit.outputs.has_changes}}"
    echo "=========="
    echo "$AUG"

输出如下

==========
/home/runner/work/_temp/_runner_file_commands/set_output_xxxxxx
==========
false
==========
false

注意 if 条件

if: ${{ steps.commit.outputs.has_changes == 'true' }}

千万不可写成

if: ${{ steps.commit.outputs.has_changes }} == true # 错误的
# 或者
if: ${{ steps.commit.outputs.has_changes == true }} # 错误的
