极狐GitLab 如何在 helm 中恢复数据

本文作者：徐晓伟

GitLab是一个全球知名的一体化 DevOps 平台，很多人都通过私有化部署 GitLab 来进行源代码托管。极狐GitLab 是GitLab 在中国的发行版，专门为中国程序员服务。可以一键式部署极狐GitLab。

本文主要讲述了如何在极狐GitLab 恢复 GitLab 历史备份数据

文档

1. 恢复 极狐GitLab 安装实例

本实例数据恢复

如果当前 极狐GitLab 实例数据被误删、实例异常，可通过历史备份进行数据恢复

记下数据库客户端的当前副本数，供后续重启使用

# -n gitlab-test：代表命名空间
# release=my-gitlab：代表 helm 安装 gitlab 时的名称
# -lapp=sidekiq：代表 sidekiq-all-in-1-v2 Deployment，默认 1 个副本
# -lapp=webservice：代表 webservice-default Deployment，默认 2 个副本
# -lapp=prometheus：代表 prometheus-server Deployment，默认 1 个副本
kubectl -n gitlab-test get deploy -lapp=sidekiq,release=my-gitlab -o jsonpath='{.items[].spec.replicas}{"\n"}'
kubectl -n gitlab-test get deploy -lapp=webservice,release=my-gitlab -o jsonpath='{.items[].spec.replicas}{"\n"}'
kubectl -n gitlab-test get deploy -lapp=prometheus,release=my-gitlab -o jsonpath='{.items[].spec.replicas}{"\n"}'

停止数据库的客户端，防止锁干扰恢复过程

kubectl -n gitlab-test scale deploy -lapp=sidekiq,release=my-gitlab --replicas=0
kubectl -n gitlab-test scale deploy -lapp=webservice,release=my-gitlab --replicas=0
kubectl -n gitlab-test scale deploy -lapp=prometheus,release=my-gitlab --replicas=0

查看 Toolbox pod

kubectl -n gitlab-test get pods -lrelease=my-gitlab,app=toolbox

# manual-backup-1-xxx：代表个人备份的 pod，无需关注
# my-gitlab-toolbox-backup-xxx-xxx：代表定时任务备份的 pod，无需关注
# my-gitlab-toolbox-xxx-xxx：代表 Toolbox pod 容器，需要记录此名称，用于后续使用
[root@anolis-7-9 ~]# kubectl -n gitlab-test get pods -lrelease=my-gitlab,app=toolbox
NAME                                      READY   STATUS      RESTARTS   AGE
manual-backup-1-9db78                     0/1     Completed   0          46h
my-gitlab-toolbox-5b7c4f8c6b-zccrv        1/1     Running     0          8m46s
my-gitlab-toolbox-backup-28393980-f9m8h   0/1     Completed   0          3h3m
[root@anolis-7-9 ~]# 

直接使用备份数据的 URL 链接恢复数据（推荐）

备份数据目录

[root@anolis-7-9 ~]# ll -h /gitlab-test/my-gitlab-minio-pv/gitlab-backups/
total 11M
-rw-rw-r-- 1 1000 1000 5.1M Dec 25 14:18 1703484999_2023_12_25_16.7.0-ee_gitlab_backup.tar
-rw-r--r-- 1 1000 1000 5.1M Dec 27 09:38 1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar
[root@anolis-7-9 ~]# 

使用 httpd 创建静态资源服务

使用其他方式创建静态资源服务也可以

docker run \
  --restart=always \
  -itd \
  --privileged=true \
  --name 2.4.48 \
  -p 180:80 \
  -v /gitlab-test/my-gitlab-minio-pv/gitlab-backups/:/usr/local/apache2/htdocs/ \
  -v /etc/localtime:/etc/localtime \
  -d httpd:2.4.48

查看静态资源

• 访问 httpd

  

使用静态资源 URL 恢复数据

kubectl -n gitlab-test exec my-gitlab-toolbox-5b7c4f8c6b-zccrv -it -- backup-utility --restore -f http://172.25.25.32:180/1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar

成功示例

[root@anolis-7-9 ~]# kubectl -n gitlab-test exec my-gitlab-toolbox-5b7c4f8c6b-zccrv -it -- backup-utility --restore -f http://172.25.25.32:180/1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar

恢复副本数量

• 使用上述命令记录的副本数进行副本恢复

kubectl -n gitlab-test scale deploy -lapp=sidekiq,release=my-gitlab --replicas=1
kubectl -n gitlab-test scale deploy -lapp=webservice,release=my-gitlab --replicas=2
kubectl -n gitlab-test scale deploy -lapp=prometheus,release=my-gitlab --replicas=1

复制备份数据到容器 Toolbox pod 内进行数据恢复（不推荐）

不推荐的原因：如果备份数据过大（例如：超过 10G），可能会存在没有复制完成的情况，导致无法解压备份数据，无法恢复

复制备份数据到容器 Toolbox pod 内

1. 查看历史备份数据

   [root@anolis-7-9 ~]# ll -h /gitlab-test/my-gitlab-minio-pv/gitlab-backups/
   total 11M
   -rw-rw-r-- 1 1000 1000 5.1M Dec 25 14:18 1703484999_2023_12_25_16.7.0-ee_gitlab_backup.tar

   [root@anolis-7-9 ~]# 

2. 复制到容器 Toolbox pod 内的 /srv/gitlab/tmp/backups 目录

   [root@anolis-7-9 ~]# kubectl -n gitlab-test cp /gitlab-test/my-gitlab-minio-pv/gitlab-backups/1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar my-gitlab-toolbox-5b7c4f8c6b-zccrv:/srv/gitlab/tmp/backups
   Defaulted container "toolbox" out of: toolbox, certificates (init), configure (init)
   [root@anolis-7-9 ~]# 
   [root@anolis-7-9 ~]# kubectl -n gitlab-test exec -it my-gitlab-toolbox-5b7c4f8c6b-zccrv ls /srv/gitlab/tmp/backups
   kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.

   1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar  gitlab-shell
   [root@anolis-7-9 ~]#

恢复数据

• 使用 容器内 /srv/gitlab/tmp/backups 目录下的部分文件名， 格式：<timestamp>_<version>

  kubectl -n gitlab-test exec my-gitlab-toolbox-5b7c4f8c6b-zccrv -it -- backup-utility --restore -t 1703640824_2023_12_27_16.7.0-ee

• 也可以使用 file:///<path> 指定文件路径绝对路径

  kubectl -n gitlab-test exec my-gitlab-toolbox-5b7c4f8c6b-zccrv -it -- backup-utility --restore -t file:///home/git/1703640824_2023_12_27_16.7.0-ee_gitlab_backup.tar
