BelugaDocker 发布工具

Beluga 是一个命令行工具，用来将 Docker 容器发布到单个服务器以及数量不多的服务器群组。

为什么不用 Kubernetes 或者 Mesos?

• 当前 Docker 不支持多租户环境




• 所以不管是 Kubernetes 还是 Mesos 都无法操作 Docker/容器层




• 很多实际的问题：




• #2918 (PR: #4572) (container root is identical to host root -- volumes can be written and read from as host root inside container).




• (WIP) Docker doesn't have any ACL. Writing to docker.sock == root.




• #5619 (PR: #6000) (absolute symlinks and symlink path components copy host target).

Beluga 不能做什么

• Down-to-distro cluster managements




• Docker registry or app management itself




• Magic service discovery




• Infrastructure management ### How is it working?

  
  
  
  

  • Run dockerfiles to build them

  
  

  • Push them to repository

  
  

  • Pull them when connected to server by ssh

  
  

  • That's it!

  
  

需求

• A Unix compatible system with RSync




• SSH




• Docker Compose




• Obviously, Docker..




• Some love.
