使用 GitHub Actions 验证构建配置

通过生成检查，您可以验证docker build配置，而无需实际运行 build。

运行检查`docker/build-push-action`

要在 GitHub Actions 工作流程中使用build-push-action, 将callinput 参数设置为check.设置此选项后，如果检测到生成配置的任何检查警告。

name: ci

on:
  push:

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - name: Login to Docker Hub
        uses: docker/login-action@v3
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}
      
      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Validate build configuration
        uses: docker/build-push-action@v6
        with:
          call: check

      - name: Build and push
        uses: docker/build-push-action@v6
        with:
          push: true
          tags: user/app:latest

运行检查`docker/bake-action`

如果你使用的是 Bake 和docker/bake-action要运行构建，则不需要需要在 GitHub Actions 工作流程中指定任何特殊输入配置。相反，请定义一个 Bake 目标，该目标调用check方法并在 CI 中调用该目标。

target "build" {
  dockerfile = "Dockerfile"
  args = {
    FOO = "bar"
  }
}
target "validate-build" {
  inherits = ["build"]
  call = "check"
}

name: ci

on:
  push:

env:
  IMAGE_NAME: user/app

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Login to Docker Hub
        uses: docker/login-action@v3
        with:
          username: ${{ vars.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Validate build configuration
        uses: docker/bake-action@v5
        with:
          targets: validate-build

      - name: Build
        uses: docker/bake-action@v5
        with:
          targets: build
          push: true
