Why is there an error in Horizontal Pod Autoscaler Yaml?

I tried the memory "averageUtilization" values with 1.5Gi and "1.5Gi" with double quotes. Can anyone check and let me know if I am missing something here?

Solution

averageUtilization:

is represented as a percent of requested memory. So you're wrong with Mi.

It should be.

averageUtilization: 65

Specify averageUtilization and a target average memory utilization over all the pods, represented as a percent of requested memory. The target pods must have memory requests configured.
