Redis Test

For simplicity of troubleshooting Redis & Redis Sentinel two docker compose files were created for each to run on a single node.

Setup services

• One Redis master
• Two Redis slaves
• Three Redis sentinels

Setup network

For simplicity an IPAM network was created with a subnet and an IP range for services with dynamic IP's

File: docker-compose-IP-Addresses.yaml

This docker compose definition runs without any problems.

File: docker-compose-Host-Names.yaml

This docker compose definition is supposed to resolve hostnames which it kind of does till you shut down the master or a sentinel. It then goes into tilt mode and doesn't fail over even when tilt timeout is increased so any adjustments to the name service would be not fruitful.
