How to measure containers start-up and end time from some API?
The kube-state-metrics job exports various Kubernetes API relates stats for Prometheus, including in kube_pod_info the Pod start time:

Actually I was able to measure up the container start time using the heapster events for a pod.For each container, inside the pod heapster captures the events, from this I was able to at least get containerCreated and ContainerStart timestamp.
