Mutliple NIC on nodes

[doron...@doit-intl.com]

Hi Guys,

I've been going over the documents and couldn't find a a clear answer.

We have a k8s service that require accessing an external service API, and it is require to be able to do so from several different public IPs.

Is there a way to achieve this? Something like attaching multiple NICs to the nodes and instructing the pod to access the "world" through a different NIC per destination, or something similar?

Thank you and all of the best,

I don't quite understand your request. Can you just rely on the Linux route table to handle this?

We have cluster's workers with multiple ENI (AWS network interfaces). Some of the pods need to bind to let's say first interface while other pods need to bind to 2nd interface. 

This is due the fact we are running a layer of about 20 proxies passing our traffic to the world and these proxies need to have unique external IP but we don't want 20 workers since each proxy pod have very small footprint.

Are you using kubernetes networking in these pods or host networking?

If you are using Kubernetes networking which network solution are you using to setup pod networking on AWS?

Hi Brandon,

We have k8s cluster we have created using kops, the internal networking is flannel.

Please let me know what further information is required.
