Disable ip allocation by pods #3372

Hi,

Can we, with annotations on each pods, disable automatic IP allocation?

I have a few containers that work without problems in IPv6 and I would like to disable IPv4 on specific pods.

rafaelvanoni commented 4 years ago

@duylong We don't have a way to express that type of configuration, but perhaps you could setup some egress policies to block IPv4 on those specific pods.

duylong commented 4 years ago

Some applications when they detect an ipv4 interface use it in priority. An Egress rule will not solve the problem.
