References:
- https://medium.com/@jielim36/basic-docker-compose-and-build-a-redis-cluster-with-docker-compose-0313f063afb6
## Steps
1. `make create-conf`
2. `make run-redis`
3. `make create-cluster`
4. Run the command below:
```
redis-cli --cluster create 172.38.0.10:6379 172.38.0.11:6379 172.38.0.12:6379 172.38.0.13:6379 172.38.0.14:6379 172.38.0.15:6379 --cluster-replicas 1
```
Desired output:
```
