Supported secondary networks for network isolation

The following secondary networks are supported in MicroShift 4.20:

  • Bridge: Allows pods on the same host to communicate with each other and the host.

  • IPVLAN: Allows pods on a host to communicate with other hosts.

    • This is similar to a MACVLAN-based secondary network.

    • Each pod shares the same MAC address as the parent physical network interface, unlike a MACVLAN-based secondary network.

  • MACVLAN: Allows pods on a host to communicate with other hosts and the pods on those other hosts by using a physical network interface. Each pod that is attached to a MACVLAN-based secondary network is provided with a unique MAC address.

Note

Setting network policies for secondary networks is not supported.
