Reproduce env:
- docker network create etcd-cluster-network
- docker-compose up -d -f docker-compose.discovery.yml
- docker ps and get id of etcd-discovery cluster
- docker exec -ti curl http://etcd-discovery:80/new?size=3
- Get the output url of the command
- Change the ETCD_DISCOVERY to the url you got previously in .env
- docker-compose up -d -f docker-compose.yml
- Check if everything works by getting any of etcd-0 container ids and execute: docker exec -ti etcdctl put greeting "text"
- And from another container of those from etcd-0: docker exec -ti etcdctl get greeting
