What happens immediately after a container is successfully started in Kubernetes, indicating its correct operation?

After a container successfully starts in Kubernetes, a key indicator of its proper operation is the transition of the container to the Running state and passing all readiness and liveness probes.

• Readiness probe indicates that the container is ready to accept traffic.
• Liveness probe confirms that the container is functioning correctly and is not stuck.

When the container has started successfully, kubelet reports to the controller that the pod is ready, and services can send requests to it. In kubectl, this is visible as STATUS: Running and READY: 1/1 (if there is one container).
