Hello, Its better to deploy 3 services with 1 replica connected to cluster, or deploy 1 service with 3 replicas? There are minimum informations about elasticsearch cluster in docker. I dont know how to aproach to this problem. Can anyone help ? Case 1.) - 3 services / 1 replica (1 docker swarm master, 2 workers) -possible to configure different settings for each node Case 2.) 1 service / 3 replicas (1 docker swarm master, 2 workers) -what about persistent data ? Data will be copied 3x ? Or have anyone experience with glusterfs? -there will be a problem with publicating port ? ingress vs publishing port. DNSRR. Others: I don not need to expose elastic port. Logstash will be in same network and it will have port exposed. -. also same for kibana, i will use elastic in coordinate mode i guess. Is this context, should I go with 3 master elastic nodes? (each: 4x E5-2690 v3 @ 2.60GHz ,16gb ram, 1GiB - 500GiB daily data traffic). Or how to design infrastructure in this case? Thanks for help. ---
