如何在 AWS CodeBuild 上运行 docker-compose？

Question

我正在尝试使用 docker-compose 在 AWS CodeBuild 上设置自动化 Rails 测试，但它出错了。

在 buildspec.yml 中：

phases:
  build:
    commands:
        - docker-compose up -d

[Container] 2018/10/23 11:27:56 Running command docker-compose up -d
Couldn't connect to Docker daemon at http+docker://localhost - is it running?
 If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.
 [Container] 2018/10/23 11:27:56 Command did not exit successfully docker-compose up -d exit status 1
[Container] 2018/10/23 11:27:56 Running command echo This always runs even if the install command fails
This always runs even if the install command fails
 [Container] 2018/10/23 11:27:56 Phase complete: BUILD Success: false
[Container] 2018/10/23 11:27:56 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: docker-compose up -d. Reason: exit status 1

大概我需要安装 docker 并启动服务，但这将在 Docker 中运行 Docker，并且需要以特权权限启动构建服务器。我只能看到用于构建 Docker 映像的示例，但我只是尝试使用它来设置运行测试的环境。

回答：在 CodeBuild 的环境部分设置 Docker 映像

感谢@mferre 回答这个问题。 Docker-compose 确实是完全支持的，不需要做任何特别的事情。关键是在 AWS CodeBuild 控制台（或通过 API 进行设置）时，在“环境”部分选择一个 Docker 映像：

也可以为现有项目指定 - 从 Build / Build Projects 中选择项目，然后从 Edit 菜单中选择 Environments。这使您可以指定图像：

您可以使用任何其他镜像并在buildspec.yml 中编写 Docker 设置脚本，但最简单的方法是使用上述官方 Docker 镜像。以此为容器，docker 和 docker-compose 已预先安装，因此 docker-compose “正常工作”。如果项目的根目录中有docker-compose.yml 文件，则buildspec.yml 可以像立即运行一样简单：

version: 0.2
phases:
  build:
    commands:
      - docker-compose up -d

Answer 1

好的，我想通了！

您需要在 CodeBuild 容器上启用“特权访问”。这将允许您与 docker cli 交互。

然后将这两行添加到安装命令中：

- nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay2& - timeout 15 sh -c "until docker info; do echo .; sleep 1; done" `

例如：

version: 0.2

phases:
  install:
    commands:
      - nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay2&
      - timeout 15 sh -c "until docker info; do echo .; sleep 1; done"
  pre_build:
    commands:
      - docker build -t helloworld .
  build:
    commands:
      - docker images
      - docker run helloworld echo "Hello, World!"

Answer 2

您是否在构建环境中使用 Docker 运行时？

我正在处理这个 repo：https://github.com/mreferre/yelb

dockercompose 并没有构建任何东西（它的目的是部署），但我相信您在此之前就遇到了问题。如果您使用 Docker 运行时，您的组合应该可以工作。

这是我的构建规范的样子：

version: 0.2
phases:
  build:
    commands:
        - cd deployments/platformdeployment/Docker
        - docker-compose up -d

这是输出：
