docker gitlab-ce 容器root密码重置小记

參考: Docker Community Edition 镜像使用帮助

ubuntu

sudo bash

切換到 root,如果需要退出，輸入exit可以退出

waka@ubuntu:~$ systemctl status docker.service

有可能是/etc/docker/daemon.json 文件配置錯誤導致的

{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}

下面镜像源是看博文时看到记下的，故记录下来了：

{
  "registry-mirrors" : ["http://ovfftd6p.mirror.aliyuncs.com"]
}

拉取 gitlab-ce時，出現

waka@ubuntu:~$ sudo docker pull gitlab/gitlab-ce:11.1.4
Error response from daemon: manifest for gitlab/gitlab-ce:11.1.4 not found: manifest unknown: manifest unknown

通過查看 docker hub上的gitlab ce tag才發現，版本號是需要帶-ce.0或其它字符的

如: 11.1.4

waka@ubuntu:~$ sudo docker pull gitlab/gitlab-ce:11.1.4-ce.0

重置gitlab ce root 用戶的密碼

進入 docker 容器命令行內，執行

# Form Docker container /bin/bash
# 執行下面的命令啓動一個 Ruby on Rails console,等待 console加載完成
