Wilfred Spiegelenburg updated YUNIKORN-3212:
--------------------------------------------
Description:
Instead of using a fixed limit based on a value in a file we should be using
the downwardapi or some helm calcullations to get the details from the pod
resource settings:
using the downwardapi we have a divisor that could help:
{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.
