Component(s)

collector

Is your feature request related to a problem? Please describe.

I need to be able to add the DNSConfig to the collector pods by way of the Operator. Today this is not exposed.

Describe the solution you'd like

That DNSConfig is exposed as a part of the OpenTelemetryCollector API.

Describe alternatives you've considered

I don't know of another way aside from a custom mutating webhook.

As a late follow up, it would be also be helpful to have DNSPolicy configurable.

@forestsword could you please describe the use-case you are trying to solve?

Sure, I'm following some internal best practices for our Kubernetes clusters where we use dnsmasq to cache and prevent overloading coredns.

The policy needs to be set to None and a custom dns configuration provided to use a local dnsmasq instead.
