软件简介

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.
