1、部署gitlab

1.1下载gitlab安装包并安装

下载地址：https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu/pool/
root@k8s-gitlab:~# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/ubuntu/pool/bionic/main/g/gitlab-ce/gitlab-ce_16.1.4-ce.0_amd64.deb
root@k8s-gitlab:~# dpkg -i gitlab-ce_16.1.4-ce.0_amd64.deb  #执行完这命令会卡顿一会，属于正常现象

GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:sudo gitlab-ctl reconfigureFor a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.mdHelp us improve the installation experience, let us know how we did with a 1 minute survey:

1.2修改gitlab配置文件

root@k8s-gitlab:~# cat /etc/gitlab/gitlab.rb
external_url 'http://gitlab.weng.org'
#修改此行
#增加下面行(可以和上面行写在一起)，可选邮件通知设置
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "2923035330@qq.com"
gitlab_rails['smtp_password'] = "jdwpvcoauyerdeed"
gitlab_rails['smtp_domain'] = "qq.com"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = false
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = "2923035330@qq.com"
#新版中增加下面行,给root用户指定初始密码才能登录
gitlab_rails['initial_root_password'] = "12345678"
prometheus['enable'] = false
prometheus['monitor_kubernetes'] =false
alertmanager['enable'] = false
node_exporter['enable'] = false
redis_exporter['enable'] = false
postgres_exporter['enable'] = false
gitlab_exporter['enable'] = false
prometheus_monitoring['enable'] =false
grafana['enable'] = false

1.3初始化和启动gitlab服务

root@k8s-gitlab:~# gitlab-ctl reconfigure  #每修改完配置文件都需执行此命令初始化

1.4验证gitlab

#查看gitlab初始化密码
root@k8s-gitlab:~# cat /etc/gitlab/initial_root_password
# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.Password: ETgsAbhaJdwitZKBKC5J2KWrK6B2gJ62L8oc1KvV2hA=# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
