#注意：為什么這里不寫https//gitlab.example.com，如果寫了https，gitLab內置nginx和外層nginx沖突，gitLab內部nginx會嘗試啟用443，而外層Nginx也在管443，結果請求來回繞，容易訪問502。

#GitLab 在 容器第一次初始化時，會生成一個隨機的 root 密碼，默認的登錄方式是：
用戶名：root
密碼：保存在容器掛載的配置目錄里（/etc/gitlab/initial_root_password）
#查看宿主機掛載位置
cat /data/gitlab/config/initial_root_password
#會有類似輸出（?。?！如果更改過root密碼就不會更新這個文件了）
# WARNING: This value is valid only in the following conditions
# ...
Password: AbCdEfGhIjKlMnOpQrSt
# ...
#如果密碼忘記，可以進入容器里重置
