GitLab基础：如何将备份恢复至更高版本的GitLab

发布时间：2020-08-21 07:17:53 ，浏览量：0

在这里插入图片描述

在前面介绍的文章中已经提到，GitLab的备份和恢复需要保证源和目的的GitLab版本一致，如果不同版本之间如何做呢？这篇文章整理和记录一下容器化方式下GitLab-ce 11.2.3的数据恢复至GitLab 12.10.5的方法。

整体思路

仍然按照GitLab官方建议，按照如下三步进行恢复： 步骤1: 目的端拉起相同版本的GitLab 步骤2: 恢复数据导 步骤3: 使用相同数据卷重建GitLab服务

事前准备

事前准备了如下版本的GitLab备份文件, 从中可以看到为11.2.3版本的数据 

liumiaocn:gitlab liumiao$ ls 1597959631_2020_08_20_11.2.3_gitlab_backup.tar 
1597959631_2020_08_20_11.2.3_gitlab_backup.tar
liumiaocn:gitlab liumiao$
步骤1: 目的端拉起相同版本的GitLab

拉起如下GitLab 11.2.3版本的服务，使用如下docker-compose.yml即可 

liumiaocn:gitlab liumiao$ cat docker-compose.yml version: '2' services: # Version Control service: Gitlab gitlab: image: gitlab/gitlab-ce:11.2.3-ce.0 ports: - "32001:80" - "30022:22" - "30443:443" volumes: - ./log/:/var/log/gitlab - ./data/:/var/opt/gitlab - ./conf/:/etc/gitlab restart: "no" liumiaocn:gitlab liumiao$

登录之后确认版本信息如下所示： 在这里插入图片描述

步骤2: 恢复数据导
  • 拷贝数据至GitLab容器之中 
liumiaocn:gitlab liumiao$ docker cp 1597959631_2020_08_20_11.2.3_gitlab_backup.tar gitlab_gitlab_1:/var/opt/gitlab/backups
liumiaocn:gitlab liumiao$
  • 确认文件与设定权限 
liumiaocn:gitlab liumiao$ docker exec -it gitlab_gitlab_1 sh
# cd /var/opt/gitlab/backups
# ls -l
total 213952
-rw------- 1 501 dialout 207134720 Aug 20 22:07 1597959631_2020_08_20_11.2.3_gitlab_backup.tar
# 
# chmod 644 1597959631_2020_08_20_11.2.3_gitlab_backup.tar
# ls -l
total 213952
-rw-r--r-- 1 501 dialout 207134720 Aug 20 22:07 1597959631_2020_08_20_11.2.3_gitlab_backup.tar
#
  • 恢复数据 

		

			高版本的GitLab可直接使用gitlab-backup进行备份与恢复，详细可参看：

			然后登录GitLab验证，酒客发现已经恢复成功了，但是此时版本仍然是：

			步骤3: 使用相同数据卷重建GitLab服务
		
		
    
			
  • 
				停止并删除当前GitLab容器
			
    • 
		


liumiaocn:gitlab liumiao$ docker-compose down
Stopping gitlab_gitlab_1 ... done
Removing gitlab_gitlab_1 ... done
Removing network gitlab_default
liumiaocn:gitlab liumiao$

		

			注意：此步骤具有风险性，如果事前有手动在容器中的修改，删除会连同此部分修改一同实施
		

		
    
			
  • 
				在同样的位置，利用之前的数据卷，拉起新的GitLab 12.10.5的服务
			
    • 
		


liumiaocn:gitlab liumiao$ vi docker-compose.yml 
liumiaocn:gitlab liumiao$ cat docker-compose.yml 
version: '2'    
services:
  # Version Control service: Gitlab
  gitlab:
    image: gitlab/gitlab-ce:12.10.5-ce.0
    ports:
      - "32001:80"
      - "30022:22"
      - "30443:443"
    volumes:
      - ./log/:/var/log/gitlab
      - ./data/:/var/opt/gitlab
      - ./conf/:/etc/gitlab
    restart: "no"
liumiaocn:gitlab liumiao$ 
liumiaocn:gitlab liumiao$ docker-compose up -d
Creating network "gitlab_default" with the default driver
Creating gitlab_gitlab_1 ... done
liumiaocn:gitlab liumiao$

		

			结果发现需要中间升级至11.11.0，详细参看 升级问题对应，将版本改为11.11.0，重新拉起服务，发现已经正常升级至11.11.0了

再次修改镜像版本，重新启动GitLab服务
		


liumiaocn:gitlab liumiao$ vi docker-compose.yml 
liumiaocn:gitlab liumiao$ cat docker-compose.yml version: '2' services: # Version Control service: Gitlab gitlab: image: gitlab/gitlab-ce:12.10.5-ce.0 ports: - "32001:80" - "30022:22" - "30443:443" volumes: - ./log/:/var/log/gitlab - ./data/:/var/opt/gitlab - ./conf/:/etc/gitlab restart: "no" liumiaocn:gitlab liumiao$ docker-compose up -d
Recreating gitlab_gitlab_1 ... done
liumiaocn:gitlab liumiao$

		

			重新启动之后发现已经正常升级至目标版本12.10.5了

			升级问题对应
		
		

			在步骤3中，重新拉起时出现了如下错误，相同的数据卷，从11.2.3换成了12.10.5，发现服务没有能够拉起来。
		


liumiaocn:gitlab liumiao$ docker-compose ps

--------------------------------------------------
gitlab_gitlab_1   /assets/wrapper   Exit 1        
liumiaocn:gitlab liumiao$

		

			进一步确认日志信息发现如下内容

			根据提示可以看到GitLab升级的时候不是一蹴而就的，可能需要多级跳，比如此处本来希望从11.2.3升级至12.10.5，需要先升到11.11.0，然后再升级，详细可参看如下说明：
在这里插入图片描述
修改版本至11.11.0之后，拉起服务，执行日志如下所示
		


liumiaocn:gitlab liumiao$ vi docker-compose.yml 
liumiaocn:gitlab liumiao$ cat docker-compose.yml 
version: '2'    
services:
  # Version Control service: Gitlab
  gitlab:
    image: gitlab/gitlab-ce:11.11.0-ce.0
    ports:
      - "32001:80"
      - "30022:22"
      - "30443:443"
    volumes:
      - ./log/:/var/log/gitlab
      - ./data/:/var/opt/gitlab
      - ./conf/:/etc/gitlab
    restart: "no"

			可以通过docker-compose logs -f显示的日志确认是否正常结束，然后查看到如下正常的状态信息了
		


liumiaocn:gitlab liumiao$ docker-compose ps
     Name             Command          State                                      Ports
