Docker部署的Gitlab平行迁移到另一台服务器上

1、镜像保存

docker save gitlab/gitlab-ce:latest -o gitlab-ce.rar

2、将以上镜像拷贝到新服务器上，然后导入

docker load -i gitlab-ce.rar

3、数据拷贝

将原服务器上docker挂载的几个目录直接拷贝到新服务器

Gitlib/etc，Gitlib/log，Gitlib/data

4、容器启动

docker run --publish 10022:22
--publish 8090:8090
--name gitlab
--privileged=true
--restart always
-v /seq_dir/Gitlib/etc:/etc/gitlab
-v /seq_dir/Gitlib/log:/var/log/gitlab
-v /seq_dir/Gitlib/data:/var/opt/gitlab
gitlab/gitlab-ce:latest

5、参考https://zhuanlan.zhihu.com/p/354941496  处理一遍

6、查看各个服务状态

docker exec gitlab gitlab-ctl status

run: alertmanager: (pid 300) 176s; run: log: (pid 291) 176s
down: gitaly: (pid 302) 176s; run: log: (pid 298) 176s
run: gitlab-exporter: (pid 337) 176s; run: log: (pid 333) 176s
run: gitlab-workhorse: (pid 305) 176s; run: log: (pid 304) 176s
down: grafana: 1s, normally up, want up; run: log: (pid 296) 176s
run: logrotate: (pid 295) 176s; run: log: (pid 292) 176s
run: nginx: (pid 311) 176s; run: log: (pid 310) 176s
run: postgres-exporter: (pid 341) 176s; run: log: (pid 338) 176s
run: postgresql: (pid 303) 176s; run: log: (pid 301) 176s
run: prometheus: (pid 309) 176s; run: log: (pid 299) 176s
run: puma: (pid 294) 176s; run: log: (pid 293) 176s
run: redis: (pid 290) 176s; run: log: (pid 287) 176s
run: redis-exporter: (pid 340) 176s; run: log: (pid 339) 176s
run: sidekiq: (pid 308) 176s; run: log: (pid 307) 176s
run: sshd: (pid 30) 192s; run: log: (pid 29) 192s

7、先解决：down: gitaly: (pid 302) 176s; run: log: (pid 298) 176s　

进入容器删除：

进入容器：docker exec -it  gitlab  bash

rm /var/opt/gitlab/gitaly/gitaly.pid

8、解决：down: grafana: 1s, normally up, want up; run: log: (pid 296) 176s

进入容器，修改该文件夹权限

chown -R gitlab-prometheus:root /var/opt/gitlab/grafana/data

9、以上处理之后可以重启gitlab的容器，所有服务器都是run状态

docker restart gitlab
