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，修改配置然后重启Pod

cat >> /mnt/data01/gitlab/conf/gitlab.rb << 'eof'
external_url 'http://123.60.108.111:30080'  ## ip需要修改为访问地址
gitlab_rails['gitlab_ssh_host'] = '123.60.108.111'  ## ip需要修改为访问地址
gitlab_rails['gitlab_shell_ssh_port'] = 30022
gitlab_rails['time_zone'] = 'Asia/Shanghai'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "1391578633@qq.com"
gitlab_rails['smtp_password'] = "yasfadsfafddfdj"  ## 密码为qq的smtp授权码
gitlab_rails['smtp_domain'] = "smtp.qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_enabled'] = true
gitlab_rails['gitlab_email_from'] = '1391578633@qq.com'
gitlab_rails['gitlab_email_display_name'] = 'gitlab'
gitlab_rails['gitlab_email_reply_to'] = '1391578633@qq.com'
gitlab_rails['gitlab_email_subject_suffix'] = '[gitlab]'
eof
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
