为什么我的 gitlab-runner(在 Docker 容器中)失败了几天，我没有改变任何东西

Question

我有一台Ubuntu 18.04服务器。在该服务器上，在docker容器中运行gitlab ce 12.7.5实例，在dockercontainer中运行gitlab runner 12.8.0。几天以来，所有的管道都出现了故障：

*Running with gitlab-runner 12.8.0 (1b659122)

gitlab runner容器的config.toml文件如下所示：

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 = 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，一切都很顺利。如果你能帮助我，我将非常高兴。谢谢！

我花了几天时间试图找到同一问题的解决方案。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，得到的配置将如下所示：

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，必须在执行这些操作后重新启动gitlab runner实例。我希望它也能帮助你。
