本分分享如何對 Helm 安裝的 Runner 進行升級。整個過程分為三步：1、確定 Runner 最新版本或者想要升級的版本是否存在；2、用 Helm upgrade 命令進行升級；3、升級確認。
極狐GitLab 為 GitLab 的中國發行版，中文版本對中國使用者更友好，可以一鍵私有化部署，安裝升級詳情可以檢視官網。
前提
- 用 Helm 安裝且執行正常的 Runner
關於使用 Helm 進行極狐GitLab Runner，可以參考文章如何用 Helm 安裝特定版本的 GitLab Runner？，然後檢視 Runner 的版本和執行狀況：
# 檢視 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
# 檢視 Runner 的執行狀態
kubectl -n jh-gitlab-runner get pods
NAME READY STATUS RESTARTS AGE
jh-gitlab-runner-gitlab-runner-5c558fb88b-lnfxm 1/1 Running 0 42h
查詢 Runner 版本
升級的前提是確定想要升級到哪個版本，使用 Helm 安裝的話，可以用 helm search命令來查詢版本：
# 查詢 Repo
helm repo list
NAME URL
jh-gitlab https://charts.gitlab.cn
# 查詢最近的 5 個版本
helm search repo jh-gitlab/gitlab-runner -l | head -5
NAME CHART VERSION APP VERSION DESCRIPTION
jh-gitlab/gitlab-runner 0.68.1 17.3.1 GitLab Runner
jh-gitlab/gitlab-runner 0.68.0 17.3.0 GitLab Runner
jh-gitlab/gitlab-runner 0.67.0 17.2.0 GitLab Runner
jh-gitlab/gitlab-runner 0.66.0 17.1.0 GitLab Runner
可以看到最新的版本是 17.3.1，而當前安裝的是 17.3.0。接下來就準備升級到 17.3.1。
Runner 的升級
執行 helm upgrade即可完成升級，升級過程中可以使用 --version執行想要升級的版本
helm upgrade --namespace jh-gitlab-runner -f values.yaml jh-gitlab-runner jh-gitlab/gitlab-runner --version 0.68.1

Runner 升級確認
用 helm ls確認 Runner 的版本資訊
helm ls --namespace jh-gitlab-runner
