Otherwise your measurement will not be correct as it will include variables that influence Kubernetes performance such as network or image size. Please remember that if you are about to measure your pod start time you have assume that all images needed to run that pod are already pre-pulled on the machine. There are of course more metrics available for the pod and other kubernetes objects here. With it you can export object creation time ( kube_pod_start_time) and object ready status ( kube_pod_status_ready). (See examples in the Metrics section below.) It is not focused on the health of the individual Kubernetes components, but rather on the health of the various objects inside, such as deployments, nodes and pods. Kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects. With already created Pod you can fetch this data using: kubectl get pod -oyamlĪnother solution that comes to my mind is Kube-state-metrics: Ready: the Pod is able to serve requests and should be added to the load balancing pools of all matching Services.In this case the maximum allowed time can be specified using the following registry value on the controller: Caution Refer to the Disclaimer at the. In some environments, in particular Cloud-based, VMs might routinely require more than 2 minutes. Initialized: all init containers have started successfully. In most environments this default time is adequate to reliably allow a VM to start-up and register.ContainersReady: all containers in the Pod are ready.PodScheduled: the Pod has been scheduled to a node.Through which the Pod has or has not passed: While there is no exact mechanism for that purpose built in Kubernetes provides pod conditions:Ī Pod has a PodStatus, which has an array of
