问题​

Go 项目如何搭建 CI/CD 流水线？

答案​

GitHub Actions​

# .github/workflows/ci.yml
name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: '1.22'

      - name: Lint
        uses: golangci/golangci-lint-action@v6

      - name: Test
        run: go test -race -coverprofile=coverage.out ./...

      - name: Coverage
        run: go tool cover -func=coverage.out

  build:
    needs: test
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v5
        with:
          go-version: '1.22'

      - name: Build
        run: CGO_ENABLED=0 go build -o app ./cmd/server

      - name: Docker Build & Push
        uses: docker/build-push-action@v5
        with:
          push: true
          tags: myregistry/app:${{ github.sha }}

CI 流程​

CD 部署​

  deploy:
    needs: build
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - name: Deploy to K8s
        run: |
          kubectl set image deployment/app \
            app=myregistry/app:${{ github.sha }}

常见面试问题​

Q1: Go 项目 CI 最少该做什么？​

答案：

  1. golangci-lint — 代码质量
  2. go test -race — 单元测试 + 竞态检测
  3. go build — 确保编译通过

这三步能拦住大部分问题。
