kubernetes基于helm部署gitlab

这篇博文介绍如何在 Kubernetes 中使用helm部署 GitLab。

先决条件

已运行的 Kubernetes 集群
负载均衡器，为ingress-nginx控制器提供EXTERNAL-IP，本示例使用metallb
默认存储类，为gitlab pods提供持久化存储，本示例使用nfs-csi

root@ubuntu:~# kubectl -n metallb-system get pods 
NAME                                  READY   STATUS    RESTARTS     AGE

部署gitlab

添加gitlab helm 仓库

helm repo add gitlab https://charts.gitlab.io

使用helm部署gitlab

helm upgrade --install gitlab gitlab/gitlab \--namespace=gitlab \--create-namespace \--timeout 600s \--set global.edition=ce \--set gitlab-runner.install=false \--set global.hosts.domain=example.com \--set certmanager-issuer.email=me@example.com

访问gitlab

获取gitlab UI root用户的登陆密码

root@ubuntu:~# kubectl -n gitlab get secret gitlab-gitlab-initial-root-password -ojsonpath='{.data.password}' | base64 --decode ; echo
bvTyB0UUwXA3VhVywKOIzdD29KVJV64LB2Td0pyzAJUYe8pcTTOFSYla1SVpXeIx

获取gitlab UI 登陆的URL地址，如果设置 global.hosts.domain=example.com，那么访问地址为

https://gitlab.example.com

配置本地域名解析，其中192.168.72.210为上文gitlab-nginx-ingress-controller service的EXTERNAL-IP

gitlab.example.com 192.168.72.210

登录gitlab后界面如下：

在这里插入图片描述

启用gitlab-runner

1、配置gitlab url在pod中的域名解析

gitlab-runner pod启用时需要从pod内部使用 gitlab 外部域名https://gitlab.example.com注册到gitlab，修改coredns配置，提供本地域名解析。

root@ubuntu:~# kubectl -n kube-system edit cm coredns
apiVersion: v1
data:Corefile: |.:53 {errorshosts {192.168.72.210 gitlab.example.comfallthrough}......}

重启coredns pods

kubectl -n kube-system rollout restart deployment.apps/coredns

2、导出gitlab自签名证书

kubectl -n gitlab get secret gitlab-gitlab-tls --template='{{ index .data "tls.crt" }}' | base64 -d > gitlab.crt

3、基于自签名证书创建secrets

kubectl -n gitlab create secret generic gitlab-runner-certs \--from-file=gitlab.example.com.crt=gitlab.crt \--from-file=registry.example.com.crt=gitlab.crt \--from-file=minio.example.com.crt=gitlab.crt

4、更新已安装的gitlab实例，启用gitlab-runner并指定secrets

helm upgrade --install gitlab gitlab/gitlab \--namespace=gitlab \--set gitlab-runner.install=true \--set gitlab-runner.certsSecretName=gitlab-runner-certs \--reuse-values

5、查看gitalb-runner pods

root@ubuntu:~# kubectl -n gitlab get pods -l app=gitlab-gitlab-runner
NAME                                    READY   STATUS    RESTARTS   AGE
gitlab-gitlab-runner-6c8cd68548-v6qpd   1/1     Running   0          5m12s

6、登陆UI查看注册的runner

选择Your work–> Admin Area
