背景

本文描述的是docker部署的Gitlab，从一台服务器迁移到另外一台服务器。

停止正在运行的容器

root@dev-server:~# docker stop gitlab.amihome.cn
gitlab.amihome.cn

传输数据目录到新服务器

用rsync命令，将gitlab容器挂载的数据目录，传输到新服务器：

root@dev-server:/mnt/disk5t/data# rsync -avz gitlab.amihome.cn [email protected]:/mnt/disk5t
The authenticity of host '192.168.3.201 (192.168.3.201)' can't be established.

检阅docker-compose.yml文件

在新服务器上，检查一下，主要是查看目录是否正确：

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# vi docker-compose.yml

内容如下：（和之前的文章略有区别，删除了一层data目录）

version: '3.6'

services:
  web:
    image: 'registry.gitlab.cn/omnibus/gitlab-jh:16.7.6'
    restart: always
    container_name: gitlab.amihome.cn
    hostname: 'gitlab.amihome.cn'
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'https://gitlab.amihome.cn'
        gitlab_rails['gitlab_shell_ssh_port'] = 2224
    ports:

      - '8929:80'
      - '2224:22'

      - '/mnt/disk5t/gitlab.amihome.cn/logs:/var/log/gitlab'
      - '/mnt/disk5t/gitlab.amihome.cn/data:/var/opt/gitlab'
      - '/home/certd/gitlab.amihome.cn:/etc/gitlab/ssl'
    shm_size: '256m'

启动容器

用docker-compose启动容器：

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker-compose up -d
Creating network "gitlabamihomecn_default" with the default driver
Pulling web (registry.gitlab.cn/omnibus/gitlab-jh:16.7.6)...

查看容器的状态：

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker ps
CONTAINER ID   IMAGE                                         COMMAND             CREATED              STATUS                                 PORTS                                                                                                                     NAMES

一个错误

多次用docker ps查看容器状态，直至最终发现容器状态是unhealthy：

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker ps
CONTAINER ID   IMAGE                                         COMMAND             CREATED         STATUS                     PORTS                                                                                                                     NAMES
d1915f6fb5de   registry.gitlab.cn/omnibus/gitlab-jh:16.7.6   "/assets/wrapper"   8 minutes ago   Up 6 minutes (unhealthy)   0.0.0.0:2224->22/tcp, :::2224->22/tcp, 0.0.0.0:8929->80/tcp, :::8929->80/tcp, 0.0.0.0:60002->443/tcp, :::60002->443/tcp   gitlab.amihome.cn

用docker logs gitlab.amihome.cn查看日志，接近尾部的时候有如下关键的一句：

……很长的日志……
2024-03-19_03:43:09.98701 22197:M 19 Mar 2024 03:43:09.986 # Fatal error loading the DB: Permission denied. Exiting.
……后边还有……

解决办法，执行下述命令：

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker exec -it gitlab.amihome.cn update-permissions

这个命令几秒就执行完毕，输出的日志很长，就不贴在这里了。
重新启动容器

root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker-compose restart
Restarting gitlab.amihome.cn ... done
root@cap-server:/mnt/disk5t/gitlab.amihome.cn# docker ps
CONTAINER ID   IMAGE                                         COMMAND             CREATED          STATUS                        PORTS                                                                                                                     NAMES
