dockerized GitLab 数据卷的移动位置

Question

我运行 GitLab 使用找到的 8.11.0-ce.1 图像 here。我这样配置 docker-compose 卷：

  volumes:
    - './data/config:/etc/gitlab'
    - './data/logs:/var/log/gitlab'
    - './data/data:/var/opt/gitlab'

但是这个磁盘的大小有限，我想将这些卷移动到更大的 /data/gitlab/ 目录。

为此，我尝试了以下步骤： 1. 关闭 docker 容器 2.复制数据卷过来(cp -r /app/gitlab/data/ /data/gitlab) 3.修改docker-compose.yml为

  volumes:
    - '/data/gitlab/config:/etc/gitlab'
    - '/data/gitlab/logs:/var/log/gitlab'
    - '/data/gitlab/data:/var/opt/gitlab'

但是，在重新启动容器后，我收到一个不断重复的错误（见下文）。我假设必须遵循额外的步骤？还是我做错了？

Answer 1

TL;DR - 尝试使用 cp -a 而不是 cp -r

详情：

我使用 https://docs.gitlab.com/omnibus/docker/#install-gitlab-using-docker-compose 上的撰写文件快速完成了此操作。我确实看到了和你一样的错误。这显然看起来是某种许可问题。我注意到容器启动时有一个方便的提示，说：

# docker-compose up
Recreating gitlab2_web_1
Attaching to gitlab2_web_1
web_1  | Thank you for using GitLab Docker Image!
web_1  | Current version: gitlab-ce=8.11.5-ce.0
web_1  |
web_1  | Configure GitLab for your system by editing /etc/gitlab/gitlab.rb file
web_1  | And restart this container to reload settings.
web_1  | To do it use docker exec:
web_1  |
web_1  |   docker exec -it gitlab vim /etc/gitlab/gitlab.rb
web_1  |   docker restart gitlab
web_1  |
web_1  | For a comprehensive list of configuration options please see the Omnibus GitLab readme
web_1  | https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
web_1  |
web_1  | If this container fails to start due to permission problems try to fix it by executing:
web_1  |
web_1  |   docker exec -it gitlab update-permissions
web_1  |   docker restart gitlab
web_1  |
web_1  | Preparing services...
web_1  | Starting services...

我尝试了这个，但取得了一些有限的成功……如图所示运行有点棘手，因为容器不断重新启动。由于您运行ning 通过撰写，您可以添加：

entrypoint: update-permissions

即像这样：

web:
  image: 'gitlab/gitlab-ce:latest'
  restart: always
  hostname: 'gitlab.example.com'
  entrypoint: update-permissions
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'https://gitlab.example.com'
      # Add any other gitlab.rb configuration here, each on its own line
  ports:
    - '80:80'
    - '443:443'
    - '22:22'
  volumes:
    - '/srv/gitlab/config:/etc/gitlab'
    - '/srv/gitlab/logs:/var/log/gitlab'
    - '/srv/gitlab/data:/var/opt/gitlab'

到相关的服务配置。它会重新创建容器，但没关系。然而，对我来说，在我这样做之后，我似乎仍然对 redis 有一些问题。

虽然这只是磁盘上的文件，但我想我会在复制时保留所有权等，这似乎工作正常。在你的情况下，我猜是：

cp -a /app/gitlab/data/ /data/gitlab

Answer 2

这些是我移动位置的 contenerized GitLab 的步骤：

运行新建GitLab实例，例如：

docker run --detach \
    --hostname gitlab.example.com \
    --publish 443:443 --publish 80:80 --publish 22:22 \
    --name gitlab \
    --restart always \
    --volume /srv/gitlab/config:/etc/gitlab \
    --volume /srv/gitlab/logs:/var/log/gitlab \
    --volume /srv/gitlab/data:/var/opt/gitlab \
    gitlab/gitlab-ce:latest

片刻后停止容器中所需的服务，以避免冲突：

docker exec -it gitlab /bin/bash -c 'gitlab-ctl stop unicorn && gitlab-ctl stop sidekiq && gitlab-ctl stop'

复制重要数据和配置文件夹到新的GitLab 来自旧 GitLab 的容器。假设你的新 GitLab 容器它被称为 gitlab 并且您的旧 GitLab 卷位置是 /srv/（参考步骤1中我的卷位置）：

docker exec -it -u git gitlab /bin/bash -c 'rsync -avz user@SERVER_LOCATION:/srv/gitlab/config/* /etc/gitlab/'
docker exec -it -u git gitlab /bin/bash -c 'rsync -avz user@SERVER_LOCATION:/srv/gitlab/logs/* /var/log/gitlab/'
docker exec -it -u git gitlab /bin/bash -c 'rsync -avz user@SERVER_LOCATION:/srv/gitlab/data/* /var/opt/gitlab/

（将 SERVER_LOCATION 替换为您的位置服务器。如果您在同一台机器上有文件，请使用 docker cp 命令。）

重启你的容器：
```
docker restart gitlab
```

几秒钟后（大约 20。取决于您的机器）更新权限文件：

docker exec -it gitlab /bin/bash -c "chown -R git /var/opt/gitlab/gitlab-rails/uploads && find /var/opt/gitlab/gitlab-rails/uploads -type f -exec chmod 0644 {} \; && find /var/opt/gitlab/gitlab-rails/uploads -type d -not -path /var/opt/gitlab/gitlab-rails/uploads -exec chmod 0700 {} \;"
docker exec -it gitlab /bin/bash -c 'update-permissions'

检查是否正确工作：

docker exec -it gitlab /bin/bash -c 'gitlab-rake gitlab:check SANITIZE=true'

（如果在此步骤中 return 有任何错误，请阅读消息并应用建议。）

生成初始迁移的备份（如果需要）：

docker exec -it gitlab /bin/bash -c 'gitlab-rake gitlab:backup:create'
