Go语言中的CI/CD：从GitHub Actions到Jenkins

前言

作为一个在小厂挣扎的Go后端老兵，我对CI/CD的理解就一句话：能自动的绝不手动。

想当年在大厂时，CI/CD是日常工作的重要部分，每天都要提交代码，触发流水线，生怕构建失败。现在到了小厂，虽然流程没那么复杂，但CI/CD的重要性依然不减，毕竟自动化是提高效率的关键。

今天就聊聊Go语言的CI/CD实践，从GitHub Actions到Jenkins，给大家一个能直接抄作业的方案。

为什么需要CI/CD？

我见过不少小团队，对CI/CD不够重视，结果导致手动部署出错，代码质量无法保证。CI/CD能带来很多好处：

自动化构建：自动编译和测试代码
持续集成：及时发现代码问题
持续部署：快速部署到生产环境
质量保证：确保代码符合质量标准

GitHub Actions

GitHub Actions是GitHub提供的CI/CD服务，它与GitHub仓库深度集成，使用方便。

基本使用

在项目根目录创建.github/workflows/go.yml文件：

name: Go CI on: push: branches: [ main, master ] pull_request: branches: [ main, master ] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Set up Go uses: actions/setup-go@v4 with: go-version: '1.20' - name: Build run: go build -v ./... - name: Test run: go test -v ./... - name: Lint run: | go install golang.org/x/lint/golint@latest golint ./...

高级配置

name: Go CI/CD on: push: branches: - main - develop pull_request: branches: - main - develop jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Set up Go uses: actions/setup-go@v4 with: go-version: '1.20' - name: Cache Go modules uses: actions/cache@v3 with: path: ~/go/pkg/mod key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }} restore-keys: | ${{ runner.os }}-go- - name: Build run: go build -v ./... - name: Test run: go test -v ./... - name: Lint run: | go install golang.org/x/lint/golint@latest golint ./... - name: Deploy to Test if: github.ref == 'refs/heads/develop' run: | ssh -i ${{ secrets.SSH_PRIVATE_KEY }} user@test-server 'cd /app && git pull && ./build.sh' env: SSH_PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }} - name: Deploy to Production if: github.ref == 'refs/heads/main' run: | ssh -i ${{ secrets.SSH_PRIVATE_KEY }} user@prod-server 'cd /app && git pull && ./build.sh' env: SSH_PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}

Jenkins

Jenkins是一个流行的开源CI/CD工具，它功能强大，可扩展性强。

安装Jenkins

使用Docker安装Jenkins：

docker run -d --name jenkins -p 8080:8080 -p 50000:50000 -v jenkins_home:/var/jenkins_home jenkins/jenkins:lts

配置Jenkins

访问http://localhost:8080完成初始设置
安装Go插件：Manage Jenkins > Manage Plugins > Available > 搜索Go Plugin
配置Go环境：Manage Jenkins > Global Tool Configuration > Go > Add Go

创建Pipeline

在Jenkins中创建一个新的Pipeline项目，配置如下：

pipeline { agent any tools { go 'go1.20' } stages { stage('Checkout') { steps { checkout scm } } stage('Build') { steps { sh 'go build -v ./...' } } stage('Test') { steps { sh 'go test -v ./...' } } stage('Lint') { steps { sh 'go install golang.org/x/lint/golint@latest' sh 'golint ./...' } } stage('Deploy') { when { branch 'main' } steps { sh 'ssh user@server "cd /app && git pull && ./build.sh"' } } } post { success { echo 'Build succeeded!' } failure { echo 'Build failed!' } } }

实战案例

以一个简单的Go Web服务为例，配置CI/CD：

项目结构

go-web-service/ ├── .github/ │ └── workflows/ │ └── go.yml ├── go.mod ├── main.go └── build.sh

代码实现

// main.go package main import ( "fmt" "net/http" ) func main() { http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { w.Write([]byte("Hello, World!")) }) fmt.Println("Server starting on port 8080") if err := http.ListenAndServe(":8080", nil); err != nil { fmt.Printf("Failed to start server: %v\n", err) } }

构建脚本

#!/bin/bash # 设置环境变量 export GO111MODULE=on export GOPROXY=https://goproxy.io,direct # 安装依赖 go mod tidy # 构建应用 go build -o app . # 重启服务 systemctl restart myapp

GitHub Actions配置

name: Go CI/CD on: push: branches: [ main, develop ] pull_request: branches: [ main, develop ] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Set up Go uses: actions/setup-go@v4 with: go-version: '1.20' - name: Cache Go modules uses: actions/cache@v3 with: path: ~/go/pkg/mod key: ${{ runner.os }}-go-${{ hashFiles('**/go.sum') }} restore-keys: | ${{ runner.os }}-go- - name: Build run: go build -v ./... - name: Test run: go test -v ./... - name: Lint run: | go install golang.org/x/lint/golint@latest golint ./... - name: Deploy to Test if: github.ref == 'refs/heads/develop' run: | echo "Deploying to test environment..." # 这里可以添加部署到测试环境的命令 - name: Deploy to Production if: github.ref == 'refs/heads/main' run: | echo "Deploying to production environment..." # 这里可以添加部署到生产环境的命令
