Create and Delete Netns

Create netns

Assume you want to create a netns named foo. (Note: do not use -, space or other strange characters in netns name!)

This is just a netns; there is only an lo interface inside it. No external network access.

systemctl start netns@foo

In this case, a veth pair will be set up automatically to tunnel packets between netns and host. Note that netns@foo.service will be started too.

systemctl start netns-bridge@foo

(For the default config, it will bridge to br0. You should create the bridge first. See wiki/bridging)

systemctl start netns-nat@foo

Just systemctl enable it.

Use this even if you started using preconfigured method:

systemctl stop netns@foo
