本文作者：徐晓伟

GitLab 是一个全球知名的一体化 DevOps 平台，很多人都通过私有化部署 GitLab 来进行源代码托管。极狐GitLab 是 GitLab 在中国的发行版，专门为中国程序员服务。可以一键式部署极狐GitLab。

本文用于处理默认帮助镜像无法下载的问题。

如果能下载默认帮助镜像，请忽略此配置，除非默认帮助镜像无法满足你的需求。

配置

  1. 查看正在运行的 job

    [root@anolis-7-9 ~]# kubectl -n gitlab-test get pod | grep runner
my-gitlab-gitlab-runner-69b59f46f-h4h9s              1/1     Running     0              17m
runner-lvpqhqhw-project-1-concurrent-0-oi5so634      2/2     Running     0              14s
[root@anolis-7-9 ~]#

  2. 查看一个 job 的详情

  3. 根据日志中的事件可知， 使用的帮助镜像是 registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-f5da3c5a， 有可能会拉取失败，可以自定义拉取镜像名称。

    如果无法访问 registry.gitlab.com 域名或拉取镜像速度较慢，可使用 docker hub 镜像、 作者 docker hub 镜像

    其中镜像标签 f5da3c5a 代表提交的 SHA 值，可通过网址 https://gitlab.com/gitlab-org/gitlab-runner/-/tags 查看语义化版本号， 一般可直接使用与 gitlab 相近的 gitlab 帮助镜像版本

  1. 导出 helm gitlab 配置

    # 将已配置的值导出到文件中
helm -n gitlab-test get values my-gitlab > my-gitlab.yaml

  2. 查看 极狐gitlab runner 默认配置

    # 此处为节选，不同版本可能会存在差异，请以 https://artifacthub.io/packages/helm/gitlab/gitlab?modal=values 中的配置为准
gitlab-runner:
  runners:
    config: |
      [[runners]]
        [runners.kubernetes]
        image = "ubuntu:22.04"
        {{- if .Values.global.minio.enabled }}
        [runners.cache]
          Type = "s3"
          Path = "gitlab-runner"
          Shared = true
          [runners.cache.s3]
            ServerAddress = {{ include "gitlab-runner.cache-tpl.s3ServerAddress" . }}
            BucketName = "runner-cache"
            BucketLocation = "us-east-1"
            Insecure = false
        {{ end }}

  3. 自定义帮助镜像

    gitlab-runner:
  runners:
    config: |
      [[runners]]
        [runners.kubernetes]
        image = "ubuntu:22.04"
        # 由上文可知
        helper_image = "gitlab/gitlab-runner:v16.6.1"
        {{- if .Values.global.minio.enabled }}
        [runners.cache]
          Type = "s3"
          Path = "gitlab-runner"
          Shared = true
          [runners.cache.s3]
            ServerAddress = {{ include "gitlab-runner.cache-tpl.s3ServerAddress" . }}
            BucketName = "runner-cache"
            BucketLocation = "us-east-1"
            Insecure = false
        {{ end }}

  4. 更新 helm gitlab 配置

    helm upgrade -n gitlab-test --install my-gitlab gitlab/gitlab -f my-gitlab.yaml --timeout 600s --version 7.7.0

  5. 等待所有 gitlab-runner 旧 pod 删除完成，新 pod 正常运行时，重试流水线，查看一个 job 的详情
