pods are not isolated by default, what you are seeing is expected 🙂

Pods are isolated from things outside the cluster by the overlay network. They are not isolated from the nodes in the cluster.

just to clarify: I can ping it from the host. does that mean that the host is actually the node or something like it? It does make sense since when i

kubectl get node

I can see that the name of the node is actually the name of my computer (the host). thank you for your answers so far 😃

node and host are generally synonymous, yes
