How to set separate outgoing (and possibly incoming) IP address for pods?

Open exander77 opened this issue 2 years ago • 4 comments

I want some of the pods to use different outgoing IP. I have set up separate ElasticIP and Gateway, how can I set pods to use it? Some ability to set route table for pod/namespace?

@exander77 - If I understand correctly you want to attach your own ENIs/secondary IPs and pods should pick them? If so you can set this env variable - https://github.com/aws/amazon-vpc-cni-k8s#disable_network_resource_provisioning-v191. Then when ENIs and IPs are attached, those IPs will be picked from IPAMD and used for pod IPs and route tables will be programmed.

I want my pod (several pods) to get separate outgoing IP, i.e. route the traffic through a different interface. I am unsure how could I use that variable? I would assume I somehow attach my ElasticIP to the cluster and to the pod.

We would need more insights on the use case. Are you available on k8s slack? We can connect and setup a call.

If it is this: https://communityinviter.com/apps/kubernetes Then I just joined.

Basically, I need separate outgoing (and possibly incoming) IP for traffic of a pod (pods).
