Hello,

I have 1 k8s master and 8 k8s worker nodes ( with persistent storage).

I need to deploy a ECK on the k8s cluster. What is the topology of ECK deployment I need to consider here ?

1. Can I go ahead with 3 ECK master , and 5 Data nodes ?

2. Do I need ingest node or can I use them as part of data nodes itself.

Any help would be really appreciated.

Thanks  
Kailas

Hi,

You can deploy all the topologies you mentioned using ECK. It is better to have 3 masters for HA, ingest nodes may help to process your documents, but in the end it's really up to you to decide which topology matches your needs and expectations. [See our documentation](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-advanced-node-scheduling.html#k8s-define-elasticsearch-nodes-roles) to understand how you can create groups of nodes and assign then some roles.

Hope it helps.

Thank you, works fine. I have gone with 3 Master and 5 data/ingest nodes.
