基本概念
GitHub Actions 是一种持续集成和持续交付 (CI/CD) 平台，可用于自动执行生成、测试和部署管道。 您可以创建工作流程来构建和测试存储库的每个拉取请求，或将合并的拉取请求部署到生产环境。
GitHub Actions 旨在帮助您建立强大而动态的自动化
GitHub 提供 Linux、Windows 和 macOS 虚拟机来运行工作流程
工作流程
- 工作流
工作流程是一个可配置的自动化过程，它将运行一个或多个作业；通过yaml文件定义。
所有的工作流都在.github/workflows
name: GitHub Actions Demo
run-name: ${{ github.actor }} is testing out GitHub Actions 🚀
on: [push]
jobs:
Explore-GitHub-Actions:
runs-on: ubuntu-latest
steps:
- run: echo "🎉 The job was automatically triggered by a ${{ github.event_name }} event."
- run: echo "🐧 This job is now running on a ${{ runner.os }} server hosted by GitHub!"
- run: echo "🔎 The name of your branch is ${{ github.ref }} and your repository is ${{ github.repository }}."
- name: Check out repository code
uses: actions/checkout@v3
- run: echo "💡 The ${{ github.repository }} repository has been cloned to the runner."
- run: echo "🖥️ The workflow is now ready to test your code on the runner."
- name: List files in the repository
run: |
ls ${{ github.workspace }}
- run: echo "🍏 This job's status is ${{ job.status }}."
if: "1 < 2"
- name: Github Context
env:
GITHUB_CONTEXT: ${{toJson(github)}}
run: echo '$GITHUB_CONTEXT'
- 事件
事件是存储库中触发工作流程运行的特定活动
- 作业
作业是工作流中在同一运行器上执行的一组步骤。 每个步骤要么是一个将要执行的 shell 脚本，要么是一个将要运行的动作。 步骤按顺序执行，并且相互依赖
- 操作（步骤）
操作是用于 GitHub Actions 平台的自定义应用程序，它执行复杂但经常重复的任务。
YAML文件
- actions引用
|-- hello-world (repository)
| |__ .github
| └── workflows
| └── my-first-workflow.yml
| └── actions
| |__ hello-world-action
| └── action.yml
// yum文件
jobs:
build:
runs-on: ubuntu-latest
steps:
# This step checks out a copy of your repository.
- uses: actions/checkout@v3
# This step references the directory that contains the action.
- uses: ./.github/actions/hello-world-action
jobs:
my_first_job:
steps:
- name: My first step
uses: actions/setup-node@v3
- 变量
steps:
- name: "Say Hello Mona it's Monday"
run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!"
env:
First_Name: Mona
- 数据共享
jobs:
deploy:
environment:
name: github-pages
url: ${{ steps.deployment.outputs.page_url }}
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v3
- name: Setup Pages
uses: actions/configure-pages@v3
- name: Upload artifact
uses: actions/upload-pages-artifact@v1
with:
# Upload entire repository
path: './docs/.vuepress/dist'
- name: Deploy to GitHub Pages
id: deployment
uses: actions/deploy-pages@v2
- 表达式
使用${{expr}}，如果使用了if关键字，可以直接写表达式
作为表达式的一部分，可使用 boolean、null、number 或 string 数据类型，表达式不能进行运算
应用
1、文档部署
2、通过curl方式发送消息
