docker-compose跑gitlab，gitlab初始化账号以及密码是什么呢？

docker-compose跑gitlab，docker-compose.yml文件如下：

version:  3 
services:
    gitlab-ce:
        image: gitlab/gitlab-ce
        container_name: gitlab-ce
        network_mode: bridge
        restart: always
        tty: true
        hostname: gitlab.dev.local
        ports: 
          - 80:80
          - 443:443
        environment:
            TZ: "Asia/Shanghai"
            GITLAB_OMNIBUS_CONFIG: |
                external_url "http://gitlab.dev.local"
                postgresql[ shared_buffers ] = "256MB"
                sidekiq[ concurrency ] = 4
                prometheus_monitoring[ enable ] = false
        volumes:
            - /data/gitlab/ce/config:/etc/gitlab
            - /data/gitlab/ce/logs:/var/log/gitlab
            - /data/gitlab/ce/data:/var/opt/gitlab

把gitlab跑起来，查看当前容器状况

CONTAINER ID   NAMES                              STATUS                           PORTS                                                                              IMAGE
db60d2386cff   gitlab-ce                          Up 36 minutes (healthy)          0.0.0.0:80->80/tcp, :::80->80/tcp, 22/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp   gitlab/gitlab-ce

这时，gitlab已经跑起来了，通过浏览器能正常访问了，那么问题来了，初始化的管理员账号是什么呢？是root，那它的密码是什么呢？
我也不知道它的密码是多少，进容器里修改root的密码
1 进入容器
2 进入gitlab的bin目录

cd /opt/gitlab/bin

3 执行gitlab-rails console

root@gitlab:/opt/gitlab/bin# gitlab-rails console

irb(main):001:0>

4 找到root的用户，输入u=User.where(id:1).first，然后回车

irb(main):001:0> u=User.where(id:1).first
=> #<User id:1 @root>

5 修改password，输入u.password= 12345678 ，然后回车

irb(main):002:0> u.password= 12345678 
=> "12345678"

6 修改确认密码

irb(main):004:0> u.password_confirmation= 12345678 
=> "12345678"

7 保存修改，输入u.save，然后回车，等到输出true，这时，密码修改成功。

irb(main):005:0> u.save
Enqueued ActionMailer::MailDeliveryJob (Job ID: d4c64606-0597-46ae-a7b5-fa9bb01c2685) to Sidekiq(mailers) with arguments: "DeviseMailer", "password_change", "deliver_now", {:args=>[#<GlobalID:0x00007fe59ae70c98 @uri=#<URI::GID gid://gitlab/User/1>>]}
=> true

至此，密码修改成功，可以用12345678密码登录进去了
