使用 docker 的编织网络驱动程序插件配置多个网络时出错
Error in configuring multiple networks using weave network driver plugin for docker
我正在浏览一篇文章 weave net driver 并且正在尝试着手研究它。我能够使用默认的 weavemesh 驱动程序在单个主机上进行容器到容器的通信。当我尝试使用 weave 网络驱动程序插件创建多个网络时出现问题。我收到以下错误。
[ankit@local-machine]$ docker network create -d weave netA
Error response from daemon: failed to parse pool request for address space "GlobalDefault" pool "" subpool "": cannot find address space GlobalDefault (most likely the backing datastore is not configured)
现在，正如我从 Getting Started with Docker Multi-host Networking 的 docker 文档中了解到的那样，它需要配置一个键值存储。我想知道我的理解是否正确？有什么方法可以在 weave 网络上创建多个网络来实现网络隔离。我希望能够在同一个盒子上将一个容器的网络流量与另一个容器 运行 隔离。
最近有一个新的 weave 1.4 plugin docker networking without cluster store plugin 公告说它支持 docker 没有外部集群存储的网络。它是如何工作的。目前还不清楚它是否可以用于在 weave.
上创建多个网络
This issue 问：
Did you start the docker daemon with --cluster-store?
You need to pass peers ips to weave launch-router $peers when starting docker with --cluster-store and --cluster-advertise.
文档提到：
The Weave plugin actually provides two network drivers to Docker
- one named
weavemesh that can operate without a cluster store and
- one named
weave that can only work with one (like Docker’s overlay driver).
因此需要先Set up a key-value store。
如果您使用的是weave插件，那么您的理解是正确的。
PR 1738 has more on the new weave 1.4+ ability to operate without a keystore with the weavemesh driver. Its doc does mention:
If you do create additional networks using the weavemesh driver, containers attached to them will be able to communicate with containers attached to weave; there is no isolation between those networks.
但是PR 1742仍然开放"Allow user to specify a subnet range for each docker host"。
