Elasticsearch in kubernetes: how to use remote filesystem?

[asp]

Hi, I want to run elasticsearch in kubernetes.

Since I understand the kubernetes paradigm this way, that "don't care on which node your stuff is running", I am hesitating with pinning elasticsearch on defined kubernetes nodes. Also the local storage may be too small, so I would like to use remote storage if possible because it can easier react growing storage. The storage admins will take care of it.

In dev environment I tired a 3 node cluster using glusterfs, but I have problems when restoring a snapshot, which is stored on nfs share.

My cluster is quite often pending between yellow and green status. I found this thread here:

Elk on Docker Swarm and glusterFS crash

Hi, I'm trying to deploy an ELK stack on docker swarm. If I bind the elastic dir data to a Docker volume there is no problem. The problems comes as soon as I try to bind the elstastic data dir to a glusterFS volume. I use glusterFS to synchronise the data between all the swarm nodes in the cluster. I deploy ELK using the following code: elasticsearch: image: docker.elastic.co/elasticsearch/elasticsearch:6.2.3 # container_name: elasticsearch environment: - "http.host=0.0.…

where you mentioned that only local filesystem or block device is supported.

What options for remote filestorage in bare metal kubernetes environment do I have?
Will elastic work well with FC storage class where I could mount a SAN device?
Any other alternatices?

Should an NFS storage work fine for snapshots?

Thanks,
Andreas
