使用gitlab runner挂载hostpah卷的正确方式是什么？

Question

我需要创建一个卷来公开maven .m2文件夹，以便在我的所有项目中重用，但我根本无法做到这一点。

我的gitlab运行器在我的kuberentes集群中作为一个容器运行。

遵循部署和配置映射

      volumes:

        name: configmap

ConfigMap：

metadata:
  name: gitlab-runner-cm
  namespace: default 
data:
  entrypoint: |
    #!/bin/bash

    set -xe

    cp /scripts/config.toml /etc/gitlab-runner/

    # Register the runner
    /entrypoint register --non-interactive --registration-token ###### --url http://gitlab.######.net --clone-url http://gitlab.######.net --executor "kubernetes" --name "Kubernetes Runner" --config "/etc/gitlab-runner/config.toml"

    # Start the runner
    /entrypoint run --user=gitlab-runner \
      --working-directory=/home/gitlab-runner \
      --config "/etc/gitlab-runner/config.toml"
  config.toml: |
    concurrent = 50 
    check_interval = 10
    [[runners]]
      name            = "PC-CVO"
      url             = "http://gitlab.######.net"
      token           = "######"
      executor = "kubernetes"
      cache_dir = "/tmp/gitlab/cache"
      [runners.kubernetes]
        [runners.kubernetes.volumes]
          [[runners.kubernetes.volumes.host_path]]
            name = "maven"
            mount_path = "/.m2/"
            host_path = "/mnt/dados/volumes/maven-gitlab-ci"
            read_only = false

          [[runners.kubernetes.volumes.host_path]]
            name = "gitlab-cache"
            mount_path = "/tmp/gitlab/cache"
            host_path = "/mnt/dados/volumes/maven-gitlab-ci-cache"
            read_only = false

但是，即使将文档中所述的[runners.kubernetes.volumes.host_path]我的卷未装载到主机上，我也尝试使用pv和pvc，但都不起作用，有人知道如何在主机上公开此.m2文件夹，以便我的所有作业都可以共享它而无需缓存吗？

Answer 1

在用内部DNS、m2卷和docker守护进程代替docker: dind解决名称解析问题后，我终于得到了一个解决问题的配置，如果有人遇到同样的问题，下面是最终的配置文件。主要的问题是，当runner被注册时，注册过程会修改config.toml文件，这会覆盖我的设置，为了解决这个问题，我在容器注册后创建了一个cat。

配置映射(这是解决方案！)
