--------------------------------------
Summary: use downwardapi for GOMEMLIMIT setting
Key: YUNIKORN-3212
URL: https://issues.apache.org/jira/browse/YUNIKORN-3212
Project: Apache YuniKorn
Issue Type: Task
Components: core - scheduler, shim - kubernetes
Reporter: Manikandan R
Assignee: Manikandan R
Instead of using a fixed limit based on a value in a file we should be using
the downwardapi to get the details from the pod resource settings:
{code:java}
{{- if .Values.resources.limits.memory }}
name: GOMEMLIMIT
valueFrom:
resourceFieldRef:
resource: limits.memory
divisor: "0.8"
{{- end }}{code}
We can store the divisor as a value in the value file if we really want. Not
sure if we want anyone to tweak that 80% number.
This needs to be tested as the doc is pretty vague on the how and what around
divisor definitions when it comes to memory.
