Cannot get Redis Cluster to run on Docker Compose - docker

Question

I'm trying to figure out how to run Redis cluster using Docker Compose.
However, I'm getting the following error:
Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:6380 -> 0.0.0.0:0: listen tcp 0.0.0.0:6380: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.
