gitlab备份恢复

数据备份

进入容器中，备份数据

bundle exec rake gitlab:backup:create RAILS_ENV=production

恢复数据

[root@test ~]# docker exec -it 05b739655a3a /bin/bash -c " bundle exec rake gitlab:backup:restore BACKUP=1508807622_2017_10_24"

报错：

Unpacking backup ... tar: 1508807622_2017_10_24_gitlab_backup.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now
unpacking backup failed

迁移的备份文件权限不足，可以给足权限，然后再恢复。
进入容器：

[root@test ~]# docker exec -it 05b739655a3a /bin/bash

数据备份是在/home/git/data/backups，但是数据恢复的时候默认去了/home/git/gitlab/backups，手动创建该目录并且将备份的数据cp至/home/git/gitlab/backups目录下。

root@test:~# mkdir /home/git/gitlab/backups
root@test:~# chown git /home/git/gitlab/backups
root@test:~# chmod 700 /home/git/gitlab/backups

如果还有报错，执行如下命令追踪报错的过程。

[root@test ~]# docker exec -it 05b739655a3a /bin/bash -c " bundle exec rake gitlab:backup:restore BACKUP=1508807622_2017_10_24  --strace"

数据恢复：

[root@test ~]# docker exec -it 05b739655a3a /bin/bash -c " bundle exec rake gitlab:backup:restore BACKUP=1508807622_2017_10_24  "

至此，数据恢复完成。

登录后查看数据是否有丢失，发现 No repository，很可能是repositories目录下的owner和gitlab的不匹配，执行如下命令，清理缓存

登录容器运行命令，将owner赋给gitlab的owner：

[root@test ~]# docker exec -it 45764742d90f  /bin/bash 
[root@test ~]#chown -R git:git /home/git/data/repositories/*

如果依然有此提示，需要清除一下缓存：

[root@test ~]# docker exec -it 24d0ddeeebe7 /bin/bash -c "bundle exec rake gitlab:backup:clear RAILS_ENV=production"

刷新页面查看，是否恢复。
