1. 将旧服务器的gitlab 镜像打包导出

[root@gitlab ~]# docker images

assaflavie/runlike      latest    e178428d4a3c   2 years ago   283MB

elleflorio/svn-server   latest    b8cc2d411214   2 years ago   49.7MB
[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
REPOSITORY         TAG           IMAGE ID       CREATED       SIZE

gitlab/gitlab-ce   latest        fe83bde77572   2 years ago   2.25GB

2. 查看旧服务器gitlab的运行信息

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 \
    --env=LANG=C.UTF-8 \
    --env=EDITOR=/bin/vi \
    --env=TERM=xterm \

    --volume=/opt/gitlab/logs:/var/log/gitlab \
    --volume=/opt/gitlab/data:/var/opt/gitlab/ \
    --volume=/etc/gitlab \
    --volume=/var/log/gitlab \
    --volume=/var/opt/gitlab \
    -p 10022:22 \
    --expose=443 \
    -p 80:80 \
    --restart=always \
    --runtime=runc \
    --detach=true \
    gitlab/gitlab-ce

已启动成功

[root@localhost gitlab]# docker ps

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
