Docker Compose方式搭建gitlab服务器

设置gitlab工作目录的环境变量 GITLAB_HOME

export GITLAB_HOME=/srv/gitlab

创建 docker-compose.yml 文件：

web:
  image: 'gitlab/gitlab-ce:latest'
  restart: always
  hostname: 'gitlab.example.com'
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'http://gitlab.example.com'
  ports:
    - '80:80'
    - '443:443'
    - '122:22'
  volumes:
    - '$GITLAB_HOME/config:/etc/gitlab'
    - '$GITLAB_HOME/logs:/var/log/gitlab'
    - '$GITLAB_HOME/data:/var/opt/gitlab'

运行 docker-compose

gitlab是个很耗资源的应用，至少需要2核4G的硬件配置。

docker-compose up -d

gitlab的docker容器启动很耗时，可能需要数分钟。如果启动未完成，访问gitlab可能出现 502错误。
硬件配置不够，gitlab的docker容器将无法成功启动。我这边本地测试2核4G的虚拟机花了4分钟的启动时间。

查看 gitlab镜像

docker images

重置gitlab管理员密码

整个网上99%的都教你用 gitlab-rails console production命令。其实可能是错的，因为不同版本可能不一样。
我的gitlab版本命令为 gitlab-rails console -e production：

gitlab-rails console -e production

查询所有的用户
user = User.all
通过条件查询用户 常见的where条件有 username email state 
user = User.where(id:1).first
user = User.find_by(email: 'admin@local.host')
通过id查询用户
user = User.find(1)

查询用户某个字段的值 显示当前用户的email
user.email

修改密码
user.password = 'new_password'
user.password_confirmation = 'new_password'
user.save
echo 'user = User.find_by(username: "root");user.password="secret_pass!";user.password_confirmation="secret_pass!";user.save' | sudo gitlab-rails console

# 修改用户状态
user.state = 'active'
user.save

端口号设置

vim /var/opt/gitlab/gitlab-rails/etc/gitlab.yml

vim /var/opt/gitlab/nginx/conf/gitlab-http.conf

gitlab-ctl restart

配置文件 /etc/gitlab/gitlab.rb
