本分分享如何对 Helm 安装的 Runner 进行升级。整个过程分为三步：1、确定 Runner 最新版本或者想要升级的版本是否存在；2、用 Helm upgrade 命令进行升级；3、升级确认。
极狐GitLab 为 GitLab 的中国发行版，中文版本对中国用户更友好，可以一键私有化部署，安装升级详情可以查看官网。
前提
- 用 Helm 安装且运行正常的 Runner
关于使用 Helm 进行极狐GitLab Runner，可以参考文章如何用 Helm 安装特定版本的 GitLab Runner？，然后查看 Runner 的版本和运行状况：
# 查看 Helm Release 以及 Runner 的版本
helm ls --namespace jh-gitlab-runner
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
jh-gitlab-runner jh-gitlab-runner 1 2024-09-11 06:50:17.139514892 +0000 UTC deployed gitlab-runner-0.68.0 17.3.0
# 查看 Runner 的运行状态
kubectl -n jh-gitlab-runner get pods
NAME READY STATUS RESTARTS AGE
jh-gitlab-runner-gitlab-runner-5c558fb88b-lnfxm 1/1 Running 0 42h
查找 Runner 版本
升级的前提是确定想要升级到哪个版本，使用 Helm 安装的话，可以用 helm search命令来查找版本：
# 查找 Repo
helm repo list
NAME URL
jh-gitlab https://charts.gitlab.cn
# 查找最近的 5 个版本
helm search repo jh-gitlab/gitlab-runner -l | head -5
