docker - Gitlab运行程序未执行作业Docker镜像

Question

我创建了一个最小的gitlab CI脚本来验证此错误:

docker_execution_test:
  image: debian:9

  script:
    - pwd
    - ls

我期望的输出是这样的:

db@theia:~/git/docker_test (master*)$ docker run -it --rm debian:9 pwd
/
db@theia:~/git/docker_test (master*)$ docker run -it --rm debian:9 ls
bin   dev  home  lib64  mnt  proc  run   srv  tmp  var
boot  etc  lib   media  opt  root  sbin  sys  usr

但是，通过gitlab-runner执行时的输出是这样的:

db@theia:~/git/docker_test (master)$ gitlab-runner exec docker docker_execution_test
Runtime platform                                    arch=amd64 os=darwin pid=49585 revision=3afdaba6 version=11.5.0

列出的工作是在整个构建过程中使用的特殊gitlab容器的内容。为什么未创建容器？我在这里想念什么？

Answer 1

事实证明，gitlab-runner正在按预期工作。令人困惑的是，它对启动的镜像进行了一些操作。
入口点将被覆盖，并且将 check out 存储库的文件夹安装到容器中，而WORKDIR指向该文件夹。

因此，尽管可以将自己的镜像作为容器运行，但必须记住，在运行任何命令之前可能需要更改文件夹。
