1、拉取映象檔案

docker pull gitlab/gitlab-ce:14.1.0-ce.0

2、啟動容器

docker run --restart=always \
-p 1443:443 -p 18080:18080  \
--name mygitlab-ce \
-v ~/gitlab/gitlab-config:/etc/gitlab \ 
-v ~/gitlab/gitlab-log:/var/log/gitlab \
-v ~/gitlab/gitlab-data:/var/opt/gitlab \
-d gitlab/gitlab-ce:14.1.0-ce.0

3、配置Gitlab地址

vi ~/gitlab/gitlab-config/gitlab.rb

;修改檔案中external_url資訊
external_url "http://IP:18080"

;重啟Gitlab
docker restart mygitlab-ce

;檢視Log，等待重啟完成
docker logs -f gitlab-ce　　

4、獲取Root密碼

;進入容器
docker exec -it mygitlab-ce bash

# 執行下面命令啟動一個 Ruby on Rails console,等待 console載入完成
root@44b33d22e70f:/# gitlab-rails console -e production
-------------------------------------------------------------------------------------
 GitLab:       11.1.4 (63daf37)
 GitLab Shell: 7.1.4
 postgresql:   9.6.8
-------------------------------------------------------------------------------------
Loading production environment (Rails 4.2.10)
irb(main):001:0> user = User.where(id: 1).first 
=> #<User id:1 @root>
irb(main):002:0> user.password="12345678" #設定密碼
=> "12345678"
irb(main):003:0> user.password_confirmation="12345678" #確認密碼
=> "12345678"
irb(main):004:0> user.save! # 儲存修改
Enqueued ActionMailer::DeliveryJob (Job ID: 38850b0d-7690-47b7-b5c9-9cf975bae8fd) to Sidekiq(mailers) with arguments: "DeviseMailer", "password_change", "deliver_now", gid://gitlab/User/1
=> true
irb(main):005:0> quit #退出 Ruby on Rails console

5、恢復備份資料（可跳過）

1. 修改這個檔案 vi /var/opt/gitlab/postgresql/data/postgresql.conf
找到listen_addresses = ” 改為listen_addresses = ‘*’

2. 修改vi /var/opt/gitlab/postgresql/data/pg_hba.conf
在這個檔案最後面加入
local all all trust
host all all 127.0.0.1/32 trust
host all all ::1/128 trust

3. 重啟gitlab生效
gitlab-ctl restart

4. 進入postgresql命令列
cd /opt/gitlab/embedded/bin
su gitlab-psql
./psql -h 127.0.0.1 gitlabhq_production

5. 執行修改gitlab使用者為超級許可權
ALTER USER gitlab WITH SUPERUSER;
退出
\q

6.停止一下服務
gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

7.修改備份檔案及備份目錄許可權
chown -R git:git /var/opt/gitlab/backups/1629939755_2021_08_26_14.1.0_gitlab_backup.tar
chown -R git:git /var/opt/gitlab/backups

8.恢復備份
gitlab-rake gitlab:backup:restore BACKUP=1629939755_2021_08_26_14.1.0

9.重啟服務
sudo gitlab-ctl start

6、重啟容器

docker restart mygitlab-ce
