kube state metrics doesn't report init container pod metrics

[thedebugger]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind feature

What happened:
Can't see pod container metrics for init containers.

What you expected to happen:
Should see pod container metrics for init container like the "main" container

How to reproduce it (as minimally and precisely as possible):
deploy a pod with an init container and check for "kube_pod_container_status_terminated" metric. It doesn't contain init metrics.

Anything else we need to know?:
The code right now only looks at ContainerStatus which doesn't provide status for InitContainers

Environment:

• All Kubernetes version
• All Kube-state-metrics image version

There should be metrics on this, however, kube-state-metrics fundamentally only produces metrics for things that can be found in the API object, meaning as long as those don’t have that information we can’t create metrics for it.

I understand. But what i can tell from source that kube-state-metrics doesn't read the init container status which is available in the API here. Right? I might be able to create a PR to include it if it makes sense. Thoughts?

[brancz]

Yes that is correct, we'd be more than happy about a PR to add these! 🙂
