Network simulations using Kubernetes

To make network tests as under Gns3, is it possible to split a cluster into subnets?
The goal would be to have pods behaving like servers/workstations as in the following diagram, to then test configurations (Dns, Ha proxy, Vpn, Ssl certificates, Ldap, ...)
Maybe it's simpler to make one cluster per subnet in VMs, these wouldn't need much cpu or memory?


  • It looks like it takes Network Policies. Or maybe put a sub-network inside a pod with several containers being either workstations or servers?
