I just deploy a nexus repository to a kubernetes cluster. This nexus have 3 docker repository. One proxy of docker hub, one private and one that group both previous.
I use haproxy as ingress controller. Is it possible to deploy an ingress that match the configuration describe here ? https://stackoverflow.com/questions/47178055/nexus3-push-to-docker-group-repo
My goal is to have only one url to push and pull to docker repository.
I post here my solution. I use custom annotation to achieve rooting to correct endpoint base on the requested url.
