Hi all, i’m trying to figure how HPA work on a pod with a sidecar container.
i have a pod that serve images with simple logic that search the image to serve looking in a database. To unload the database and speedup things i added a sidecar container with with nginx acting as a caching proxy. Each container has is own resource request definition.
Things work well but i can’t figure out how the HPA evaulate metrics to decide when scale up.
Now the HPA scale up on 80% cpu request usage, but looking at the metrics i don’t understand if it evaluate only one of the two containers and in what order, or if it evaluete the grouped cpu requests consumption.
