could you pls try that the

make deploy-full-local-setup still works as described in https://www.k8gb.io/docs/local.html ? I think we need to upgrade the ingress and service also here:

• https://github.com/k8gb-io/k8gb/blob/master/deploy/ingress/nginx-ingress-values.yaml#L29
• https://github.com/k8gb-io/k8gb/blob/master/deploy/ingress/udp-services.yaml#L9

otherwise lgtm

edit: maybe also here: https://github.com/k8gb-io/k8gb/blob/master/Makefile#L438

@jkremser terratest setup in CI spins up pretty much the same setup as deploy-full-local-setup. From ingress/service perspective it is still the same port 53, the change is Deployment runs on port 5353 and svc's targetPort specifies that. This is transparrent to the upper stack
