Chapter 13. Managing Pod Networks

When your cluster is configured to use the ovs-multitenant SDN plug-in, you can manage the separate pod overlay networks for projects using the administrator CLI.

To join projects to an existing project network:

$ oadm pod-network join-projects --to=<project1> <project2> <project3>

In the above example, all the pods and services in <project2> and <project3> can now access any pods and services in <project1> and vice versa.

Alternatively, instead of specifying specific project names, you can use the --selector=<project_selector> option.

To allow projects to access all pods and services in the cluster and vice versa:

$ oadm pod-network make-projects-global <project1> <project2>

In the above example, all the pods and services in <project1> and <project2> can now access any pods and services in the cluster and vice versa.

Alternatively, instead of specifying specific project names, you can use the --selector=<project_selector> option.
