备份
查看之前docker的启动命令
history|grep run
docker run -i --name gitlab \
--restart=always \
-p 8022:22 \
-p 80:80 \
-p 8443:443 \
-v /home/gitlab/etc:/etc/gitlab \
-v /home/gitlab/log:/var/log/gitlab \
-v /home/gitlab/data:/var/opt/gitlab \
twang2218/gitlab-ce-zh
docker ps 查看旧gitlab的containId
docker exec -it xx /bin/bash 进入旧gitlab的容器里面
执行命令gitlab-rake gitlab:backup:create，生成文件1729667793_2024_10_23_11.10.1_gitlab_backup.tar,文件所在容器内的目录是
/var/opt/gitlab/backups/；
或者在宿主机搜文件名字， find / -name 1729667793_2024_10_23_11.10.1_gitlab_backup.tar
安装
在旧服务器上docker save -o /home/gitlab_new.tar gitlab_new
在新的服务器上安装docker（步骤省略）
导入旧gitlab导出的gitlab_new.tar
docker load </home/gitlab_new.tar
启动
docker run -i --name gitlab \
--restart=always \
-p 8022:22 \
-p 80:80 \
-p 8443:443 \
-v /home/gitlab/etc:/etc/gitlab \
-v /home/gitlab/log:/var/log/gitlab \
-v /home/gitlab/data:/var/opt/gitlab \

然后把旧的gitlab备份的 1729667793_2024_10_23_11.10.1_gitlab_backup.tar 、gitlab.rb 和gitlab-secrets.json 导入到新的容器里面的/opt目录
docker cp /home/1729667793_2024_10_23_11.10.1_gitlab_backup.tar containId:/opt
docker cp ...
dcoker cp ...
docker exec -it containId /bin/bash
把刚导入的tar包移动到/var/opt/gitlab/backups/
在容器执行命令
gitlab-rake gitlab:backup:restore BACKUP=1729667793_2024_10_23_11.10.1
把gitlab.rb 和gitlab-secrets.json移动到/etc/gitlab/目录
并设置权限chmod 777
容器内重启gitlab
gitlab-ctl restart
如遇到页面访问异常问题：
ip地址映射问题，修改vim /etc/gitlab/gitlab.rb
external_url 'xxx.xxx.xxx.xxx'
gitlab_rails['gitlab_ssh_host'] = 'xxx.xxx.xxx.xxx'
gitlab_rails['gitlab_shell_ssh_port'] = 9922
gitlab-ctl reconfigure
修改gitlab.yml
vim /var/opt/gitlab/gitlab-rails/etc/gitlab.yml
host:xxx.xx.xx.xx
port:80
https:false
gitlab-ctl restart
