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GitLabGitLab 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

ini 复制代码
# -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

ini 复制代码
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

ini 复制代码
kubectl -n gitlab-test get pods -lrelease=my-gitlab,app=toolbox
perl 复制代码
# 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

yaml 复制代码
[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

ruby 复制代码
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

perl 复制代码
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

vbnet 复制代码
[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
ini 复制代码
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

    yaml 复制代码
    [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 ~]# 
  2. 复制到容器 Toolbox pod 内的 /srv/gitlab/tmp/backups 目录

    csharp 复制代码
    [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.
    Defaulted container "toolbox" out of: toolbox, certificates (init), configure (init)
    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>

    perl 复制代码
    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

    perl 复制代码
    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
