Apply node-specific DaemonSet configuration

Question

I've got 4 nodes in a kubernetes cluster and a metric exporter for prometheus that has to run on each node, each one exposing the nodes individual metrics. This exporter fetches the necessary data via UDP from another deployment, lets call it provider, on the same node.

So, the desired setup looks like this:

• node01:

  • exporter01
  • provider01

• node02:

  • exporter02
  • provider02

[...]

One would guess, okay if exporter and provider are needed on all nodes each, lets use a DaemonSet for it and kubernetes will spread the deployments across the nodes. It's unfortunately not so easy because exporter and provider are configured via ENVs, say IP and Port, so their communication via UDP works. So, each of these pods have to be configured differently which, afaik, is not possible with a DaemonSet.

Question

I could achieve this probably with 4 different deployments with a nodeSelector each. Similarly, I could create 4 services for the provider instances so the exporter could reach it this way. But is there a better solution that, ideally, doesnt require 4 resources that are 90% the same?
