[bitnami/external-dns] Allowing for customize dnsPolicy and dnsConfig for external-dns deployment

[chaijunkin]

Name and Version

bitnami/external-dns 6.36.1

What is the problem this feature will solve?

external-dns usually called external DNS outside from the cluster, which may caused NXDOMAIN "error" in CoreDNS. This feature allowed users to customize the workload DNS resolution.

What is the feature you are proposing to solve the problem?

There was no way to set dnsConfig or dnsPolicy for kubernetes workload, thus making it impossible to set custom nameserver and custom nameserver config for the pod.

Similar feature to this PRs Kafka DNSPolicy and DNSConfig or kubernetes-sigs/external-dns PR.

I'm planning to contribute.

What alternatives have you considered?

No response
