What are advanced probes in Kubernetes pods?

Advanced probes in Kubernetes are mechanisms to check the health and readiness of your application running in pods. They include liveness and readiness probes that can be configured to use HTTP requests, TCP sockets, or command execution.

How do I configure a liveness probe?

To configure a liveness probe, you can specify it in your pod's YAML file under the livenessProbe section. You can choose the type of probe (HTTP, TCP, or Exec) and set parameters like initialDelaySeconds, timeoutSeconds, and periodSeconds.

Can you give me an example of a readiness probe?

Sure! Here's an example of a readiness probe using an HTTP GET request:

readinessProbe:
  httpGet:
    path: /healthz
    port: 8080
  initialDelaySeconds: 5
  periodSeconds: 10

What happens if a liveness probe fails?

If a liveness probe fails, Kubernetes will restart the pod to try to recover it. This helps ensure that your application remains available and responsive.
