Issue description

The compose.yaml file networking is incorrect, as in step 4, we are asked to isolate the container quotes-ui from the quotes-provider and quotes-api.

However, not defining the network for the quotes-ui container doesn't isolate anything by itself, as podman will attach the container to the default network, lab-net, in this case.

This step is very misleading for the student. Actually isolating the container from the other two containers by explicitly adding another network, makes the container fail because nginx can't find the upstream quotes-api host.

So in the end the step 4 for isolation doesn't make any sense for this particular application, that needs all their parts interconnected.{}
