talk to other VMs in your project. This is the same basic model.
Kubernetes IP addresses exist at the `Pod` scope - containers within a `Pod`
share their network namespaces - including their IP address. This means that
containers within a `Pod` can all reach each other's ports on `localhost`. This
also means that containers within a `Pod` must coordinate port usage, but this
is no different from processes in a VM. This is called the "IP-per-pod" model.

How this is implemented is a detail of the particular container runtime in use.
