为什么几天后我的 gitlab-runner（在 Docker 容器中）失败了，我没有做任何改变

Question

我有一个 Ubuntu 18.04 服务器。在此服务器上运行 docker 容器中的 gitlab-ce 12.7.5 实例和 docker 容器中的 gitlab-runner 12.8.0 实例。几天以来，所有管道都失败了：

*Running with gitlab-runner 12.8.0 (1b659122)
  on ddddd kbuTsA6j
Using Docker executor with image ubuntu:18.04 ...

Pulling docker image ubuntu:18.04 ...

gitlab-runner容器的config.toml文件是这样的：

concurrent = 1
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "ddddd"
  url = "https://myreplacedname.stratoserver.net:8929/"
  token = "kbuTsA6jgE_GrM"
  tls-ca-file = "/etc/gitlab-runner/certs/myreplacedname.stratoserver.net.crt"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
  [runners.docker]
    tls_verify = false
    image = "docker:19.03.1"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/srv/gitlab-runner/config:/etc/gitlab-runner", "/cache", "/builds:/builds"]
    shm_size = 0

直到几天前，一切正常。如果你能帮助我，我会很高兴。谢谢！

我花了几天时间试图找到解决同一问题的方法。我发现将值 false 分配给 [runners.docker] 部分的 privileged 字段可以解决这个问题。

因此，在您的情况下，生成的配置将如下所示：

concurrent = 1
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "ddddd"
  url = "https://myreplacedname.stratoserver.net:8929/"
  token = "kbuTsA6jgE_GrM"
  tls-ca-file = "/etc/gitlab-runner/certs/myreplacedname.stratoserver.net.crt"
  executor = "docker"
  [runners.custom_build_dir]
  [runners.cache]
    [runners.cache.s3]
    [runners.cache.gcs]
  [runners.docker]
    tls_verify = false
    image = "docker:19.03.1"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/srv/gitlab-runner/config:/etc/gitlab-runner", "/cache", "/builds:/builds"]
    shm_size = 0

当然，要应用这些更改，您必须在执行这些操作后重新启动 gitlab-runner 实例。希望对你也有帮助。
