Question

我在本地安装了gitlab-runner。

km@Karls-MBP ~ $ gitlab-runner --version
Version:      10.4.0
Git revision: 857480b6
Git branch:   10-4-stable
GO version:   go1.8.5
Built:        Mon, 22 Jan 2018 09:47:12 +0000
OS/Arch:      darwin/amd64

泊坞：

km@Karls-MBP ~ $ docker --version
Docker version 17.12.0-ce, build c97c6d6

.gitlab-ci.yml：

image: docker/compose:1.19.0

before_script:
  - echo wtf

test:
  script:
    - echo test

结果：

km@Karls-MBP ~ $ sudo gitlab-runner exec docker --docker-privileged test

不知道问题是什么。

Answer 1

似乎docker/compose图像配置为docker-compose作为入口点。

您可以在 .gitlab-ci.yml 文件中override the default entrypoint泊坞窗/撰写图片：

image: 
  name: docker/compose:1.19.0
  entrypoint: [""]

before_script:
  - echo wtf

test:
  script:
    - echo test

Answer 2

docker/compose映像具有命令docker-compose作为其入口点（直到1.24.x版），其用法与此类似（假定兼容的卷挂载）：

docker run --rm -t docker/compose -f some-dir/compose-file.yml up

不幸的是，该功能使其与GitLab CI的Docker Runner中的使用不兼容。从理论上讲，您可以有一个这样的构造：

job-name:
    image: docker/compose:1.24.1
    script:
        - up
        - --build
        - --force-recreate

但是，GitLab Docker Runner假定入口点是/bin/bash-或至少具有同样的功能（许多Docker映像都以深思熟虑的方式使用外壳脚本，其中"$@"作为入口点的最后一行）-从您为脚本指定的数组元素会动态创建自己的临时shell脚本。它以set -e和set -o pipeline之类的语句开头，并将在sh temporary-script.sh之类的语句中用作容器命令。这就是导致您收到意外错误消息的原因。

此行为最近是documented more clearly：

Docker执行程序不会覆盖Docker映像的ENTRYPOINT。

这意味着，如果您的映像定义了ENTRYPOINT并且不允许使用CMD运行脚本，则该映像将无法与Docker执行器一起使用。

使用[""]覆盖入口点将允许在docker/docker-compose（版本1.25.x之前）中使用Docker Runner，但是GitLab即时创建的脚本不会作为进程运行1，因此该容器不会在脚本结尾处停止。示例：

job-name:
    image:
        name: docker/docker-compose
        entrypoint: [""]
    script:
        - docker-compose
        - up
        - --build
        - --force-recreate

在撰写本文时，docker/docker-compose的最新版本是1.25.0-rc2。您的里程可能会有所不同，但这足以满足我的目的，并且可以完全解决这两个问题。

gitlab-runner local - 没有这样的命令
