Hi,
I am running kibana in k8s with requests/limits set for cpu & ram. Upper memory limit is 2GB. I'm seeing periodic out of memory errors and am going to raise the upper container limit.
Given that I have been seeing out of heap errors how do I set the max heap so that it matches the container memory limit?
Thx
D

Hi dawiro
Thanks for reaching out to us. Kibana is running on node.js, we don't recommend to change it's memory settings, I'll ask for you what's a recommended minimum memory spec for Kibana
Best,
Matthias

I've asked our operations team, 2GB is usually a good value, you should define the memory in the following way:
NODE\_OPTIONS=--max\_old\_space\_size=2048
Best,

Does this mean that the guidance to not explicitly set memory options no longer applies? Users are going to become confused...
Thx

Yes, you can do that in container context!
