I am running a reactJs application in Production mode inside a Kubernetes pod.container runtime is docker. Pod status is Running but still we don't get UI. Also when I check logs I see the below JS stacktrace error. To run React application I have given below command
"build": "set max_old_space_size=8192 && webpack --mode production --max_old_space_size=8192 && serve -s dist -l 3000"
The error I see inside pod logs is
FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory<--- Last few GCs --->

You need to do one of the following:
1. Change your pod spec to reserve an amount more than 8192.
2. Change your command to set --max_old_space_size to a value under 1024.
3. Or change both, but you need to make sure your pod has enough memory
What happens if you just remove both of the max_old_space_size altogether? Do you really need to override this?
