K8s上安装gitlab-ce

前言
  使用pv-pvc来持久化gitlab的数据，配置，日志文件。
  pod启动后需要需要修改external_url然后重启pod。

操作如下

mkdir -p /mnt/data01/gitlab
ctr -n k8s.io i pull docker.io/gitlab/gitlab-ce:latest
kubectl label node [node_name] app=devops
kubectl apply -f gitlab-deployment.yml

如果镜像拉取不下来，可以

wget -c http://117.72.10.233/file/gitlab-ce.tgz
ctr -n k8s.io i import gitlab-ce.tgz

Pod起来之后，修改 /mnt/data01/gitlab/conf/gitlab.rb 文件，如下图所示修改，然后

kubectl get pods -n devops
kubectl delete pod [上面的gitlab的podname] -n devops

最后浏览器访问ip:30080即可访问gitlab，账号是root，密码是初始密码执行grep 'Password' /mnt/data01/gitlab/conf/initial_root_password
