hash_ring
~~~~~~~~~~~~~~
Implements consistent hashing that can be used when
the number of server nodes can increase or decrease (like in memcached).
Consistent hashing is a scheme that provides a hash table functionality
in a way that the adding or removing of one slot
does not significantly change the mapping of keys to slots.

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
