YvesZelros commented 3 months ago

Kubernetes v1.29 have introduce sidecar containers

https://kubernetes.io/docs/concepts/workloads/pods/sidecar-containers/

Sidecar containers are used as exemple by istio

kube-capacity -p should print sidecar containers resource usage

Note: sidecar containers are visible with kubectl top pods --containers=true

I also agree that this project should take initContainers as well as sidecar containers into account. There's non trivial calculation that goes into calculating what stage the container in, how much does that initContainer –or containers[]+sidecars[] request.
