Hi!
I've deployed a cluster following this guide to Kubernetes in GKE. One of my ES nodes was evicted for using too much memory.
I wasn't running anything overnight on the cluster. How can I ensure Elasticsearch doesn't get evicted in the future?

One thing I should add is that I had turned on stack monitoring.

Hi @j-rewerts you can configure resource request/limits, as well as JVM heap size, as described in the latter half of this sample:
# This sample sets up an Elasticsearch cluster with 3 nodes.
apiVersion: elasticsearch.k8s.elastic.co/v1alpha1
kind: Elasticsearch
metadata:
name: elasticsearch-sample
spec:
version: 7.2.0
nodes:
- config:
# most Elasticsearch configuration parameters are possible to set, e.g:
node.attr.attr_name: attr_value
node.master: true
node.data: true
node.ingest: true
node.ml: true
podTemplate:
metadata:
labels:
# additional labels for pods
foo: bar
show original
