Probes

In this blog we will be talking about Liveness, Readiness and Startup probes of a container. A Service in Kubernetes is an abstraction which defines a logical set of Pods and a policy by which to access them. — - Life without a service What is Kubelet? # Kubelet is a primary node agent that runs on every node. Works in term of PodSpec, that describes a POD (JSON or Yaml). Liveness Probe # It is used by kubelet to decide when to restart the container. periodSeconds defines when the kubelet check periodically. initialDelaySeconds specifies the initial wait before checking. I just created a single container pod that will run touch command to create a file and then it deletes that specific file after a delay, on which the livenessProbe is listening on and then once liveness fails we can check the container.
