[root@gitlab ~]# docker save -o gitlab.tar gitlab/gitlab-ce:latest
导入到新服务器
[root@localhost ~]# docker load -i gitlab.tar
Loaded image: gitlab/gitlab-ce:latest
[root@localhost ~]# docker images

在新服务器创建相同版本的gitlab容器
创建映射目录
[root@localhost opt]# mkdir gitlab
[root@localhost opt]# cd gitlab/
[root@localhost gitlab]# mkdir logs data config
新服务器运行容器
docker run \
--name=gitlab \
--hostname=172.16.140.11 \
--env=PATH=/opt/gitlab/embedded/bin:/opt/gitlab/bin:/assets:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin \

迁移备份和恢复
将旧服务器下的gitlab备份文件复制到新服务器的gitlab备份目录下
[root@localhost backups]# ll
总用量 24877100
-rw-r--r--. 1 root root 25474150400 3月 27 11:30 1711476565_2024_03_26_14.2.3_gitlab_backup.tar
[root@localhost backups]# chmod +777 1711476565_2024_03_26_14.2.3_gitlab_backup.tar
[root@localhost backups]# ll
总用量 24877100
-rwxrwxrwx. 1 root root 25474150400 3月 27 11:30 1711476565_2024_03_26_14.2.3_gitlab_backup.tar
恢复备份
进入容器
[root@localhost backups]# docker exec -it 2095 /bin/bash
停止相关数据连接服务
root@a88968cb1dcc:/var/opt/gitlab/backups# gitlab-ctl stop unicorn
root@a88968cb1dcc:/var/opt/gitlab/backups# gitlab-ctl stop sidekiq
ok: down: sidekiq: 1s, normally up
进入目录/var/opt/gitlab/backups
cd /var/opt/gitlab/backups
加载备份文件
root@a88968cb1dcc:/var/opt/gitlab/backups# gitlab-rake gitlab:backup:restore BACKUP=1711476565_2024_03_26_14.2.3
等待备份文件加载完成，中间会出现几次交互，大概意思就是加载备份会删除现有数据，是否确定，都输入yes就可以
如果遇到错误：must be owner of extension plpgsql
参考：https://www.jianshu.com/p/09a2b0c25ecd
提示：
Do you want to continue (yes/no)? yes
Deleting backups/tmp ... done
Warning: Your gitlab.rb and gitlab-secrets.json files contain sensitive data
and are not included in this backup. You will need to restore these files manually.
Restore task is done.
需要把原来的gitlab.rb和gitlab-secrets.json 拷贝到现配置文件目录下
并修改url地址
[root@localhost config]# vim gitlab.rb
external_url 'http://172.16.140.11'
[root@localhost gitlab]# vim data/gitlab-rails/etc/gitlab.yml
gitlab:
## Web server settings (note: host is the FQDN, do not include http://)
host: 172.16.140.11
port: 80
https: false
重新加载配置
root@172:/var/opt/gitlab/backups# gitlab-ctl reconfigure
