前言

本文记录下基于docker安装gitlab并重置管理员密码的过程。

作为记录的同时也希望能帮助到需要的朋友们。

搭建过程

1. 准备好docker环境并启动docker

[root@slave-node1 docker-gitlab]# docker version
Client:
 Version:           18.06.1-ce
 API version:       1.38
 Go version:        go1.10.3
 Git commit:        e68fc7a
 Built:             Tue Aug 21 17:23:03 2018
 OS/Arch:           linux/amd64
 Experimental:      false

Server:
 Engine:
  Version:          18.06.1-ce
  API version:      1.38 (minimum version 1.12)
  Go version:       go1.10.3
  Git commit:       e68fc7a
  Built:            Tue Aug 21 17:25:29 2018
  OS/Arch:          linux/amd64
  Experimental:     false

[root@slave-node1 docker-gitlab]# systemctl status docker

....省略部分日志

2. 创建文件夹并运行容器

# 新建文件夹用于存储数据和日志
mkdir -p /opt/docker-gitlab

# 拉取镜像、创建并运行容器
docker run -d -p 13443:443 -p 13888:80 -p 13222:22 --name gitlab --restart always -v /opt/docker-gitlab/config:/etc/gitlab -v /opt/docker-gitlab/logs:/var/log/gitlab -v /opt/docker-gitlab/data:/var/opt/gitlab gitlab/gitlab-ce

首次启动过程比较慢，可以通过docker logs -f gitlab --tail 200实时查看启动日志。

3. 尝试访问

启动完成后访问服务器ip:13888即可看到gitlab首页
登录页面
默认密码不清楚，网上很多说法是用户名是root，密码是: 5iveL!fe 我试了下是进不去的，可能是版本升级后更换了默认密码吧。

补充说明:

后面在研究单点登录配置的时候发现在宿主机的/opt/docker-gitlab/config目录下存在initial_root_password这个文件，文件中包含了root密码，第一次登录可以使用这个密码，亲测有效。登录后建议还是要修改这个默认密码。

文件内容如下:

[root@slave-node1 config]# pwd
/opt/docker-gitlab/config
[root@slave-node1 config]# ls -ll
total 176
-rw-------. 1 root root 128291 Aug  9 11:52 gitlab.rb
-rw-------. 1 root root  19103 Aug  9 13:52 gitlab-secrets.json
-rw-------. 1 root root    749 Aug  9 11:52 initial_root_password

-rw-r--r--. 1 root root     99 Aug  9 11:52 ssh_host_ed25519_key.pub

drwxr-xr-x. 2 root root      6 Aug  9 11:53 trusted-certs
[root@slave-node1 config]# cat 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.

# 没错这个就是root对应的初始密码了。

# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.

4. 修改ROOT密码

修改密码需要使用gitlab自带的控制台命令行工具，需要进入到容器中执行。

[root@slave-node1 docker-gitlab]# docker exec -it gitlab bash
root@ac5a942b141f:/# cd /opt/gitlab/
root@ac5a942b141f:/opt/gitlab# ls -ll
