Tutorial "Bundle a Node.js app within a rock" does not work

[Bruno Hildenbrand]

Bug Description

In the tutorial Bundle a Node.js app within a rock, just after the docker run command, one is instructed to navigate to http://localhost:8000. You should see a blank page with a “Hello World from inside the rock!”.

However, if you're following the tutorial as instructed from a Multipass VM, this fails as the app is only accessible from inside the Multipass VM, not from the host itself.

To Reproduce

1. Run the tutorial inside a Multipass host as instructed by the article
2. Try to open your web browser and navigate to http://localhost:8000

Error:

This site can’t be reached
localhost refused to connect.

The documentation should either instruct to expose the service on the Multipass host or recommend to open another shell into the Multipass VM and curl http://localhost:8000
