Test Redis v4 and v6 cluster

Start it up

docker-compose up

Create cluster of v4 instances

docker-compose exec master-6 redis-cli --cluster create \
	$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' redis46_master-{0,1,2}_1 | xargs -I% echo %:6379)

Join in the v6 instance

docker-compose exec master-6 redis-cli --cluster add-node  \
  $(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' redis46_master-6_1):6379 \
  $(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' redis46_master-0_1):6379

Check

docker-compose exec master-6 redis-cli cluster nodes                                                                                                                            <<<

Assign some slots to the v6

docker-compose exec master-6 redis-cli --cluster rebalance --cluster-use-empty-masters \
