How to use the Weave network, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Weave is a container network solution developed by Weaveworks. The virtual network created by weave connects containers deployed on multiple hosts. To containers, weave is like a huge Ethernet switch, all containers are connected to this switch, and containers can communicate directly without the need for NAT and port mapping. In addition, weave's DNS module makes the container accessible through hostname.

Description of experimental environment

Weave does not rely on distributed databases (such as etcd and consul) to exchange network information, and a cross-host container network can be established by running weave components on each host. We will deploy weave on host1 and host2 and implement the features of weave.

Install and deploy weave

Weave installation is very simple, execute the following command on host1 and host2:

Curl-L git.io/weave-o / usr/local/bin/weave

Chmod axix / usr/local/bin/weave

Start weave in host1

Execute the weave launch command in host1 to start the weave related services. All components of weave run as containers, and weave downloads the latest image from docker hub and starts the container.

Weave runs three containers:

Weave is the main program, which is responsible for establishing weave network, sending and receiving data, providing DNS services and so on.

Weaveplugin is the libnetwork CNM driver that implements the Docker network.

Weaveproxy provides a proxy service for the Docker command, which automatically adds the container to the weave network when the user runs Docker CLI to create the container.

Weave creates a new Docker network weave:

Driver is in the range of weavemesh,IP 10.32.0.0amp 12.

Docker network inspect weave

.

"Config": [

{

"Subnet": "10.32.0.0amp 12"

}

]

.

Weave has been installed and configured.
