I have been working through the Tutorial at docker docs. Using localhost to access containerized application works fine when run as a standalone container. However, it fails as soon as I deploy it through Kuberbetes or Swarm.

Under Part 3 of the tutorial I successfully deploy to Kubernetes (using micro8s.kuberbetis)

kubectl apply -f bb.yaml

and I get

deployment.apps/bb-demo created
service/bb-entrypoint created

However, I cannot use Chrome to visit the application pages. Using localhost:30001 with Chrome, it says "Waiting on cache..." and then "Waiting on localhost..." forever.

I tried visting it through Firefox and it works fine.
