where are you doing those lookups? those only work from within a pod that is using cluster DNS. not from the outside world.

Thank you, I'll check that out. I was doing those DNS queries from outside a pod.

yeah that’s not going to work. cluster DNS only works from inside the cluster. From outside the cluster, you’re expected to use ingress and/or manage your own DNS to point things at the nodes (or the loadbalancer IP if using an external load-balancer controller)

I have a feeling that the example is broken on a mismatch between

redis-slave

and

redis-replica

.

the guestbook pod should be able to resolve redis-master, redis-master.default, or redis-master.default.svc

is there a way to do something like

docker exec -ti

to get into a pod?

yep

ok, ty!
