Use internal cluster registry to pull image

[fatihdestegul]

Hi community,

Not sure if this is the right place to raise this idea/question but will give it a try.

Problem

• I have 3 multi-node cluster on prem which doesn't have internet access. (Each of clusters configs are federated by GitOps approaches.)
• I have an internal registry in each cluster. (1 for each, 3 in total.) Registry is serving a pod. (e.g. Harbor)

Question/Idea In a federated environment each cluster has a different domain. (e.g. myregistry-1.com, myregistry-2.com, myregistry-3.com) Therefore, each registries have different FQDNs. To deploy the same applications into 3 different clusters/regions, I need to change image FQDNs accordingly.

Is it possible to have a common DNS, such as myregistry.local for all clusters so that kubelet will be able to download images locally from local registry, which is basically a pod..

Ps: This is something different than configuring a local registry, because my registry runs as a pod and kubelet doesn't know anything about it...
