What are Kubernetes probes and how do I use them?

Kubernetes probes are used to check the health of your applications running in containers. There are two main types: liveness probes and readiness probes.

What's the difference between liveness and readiness probes?

Liveness probes determine if a container is running. If it fails, Kubernetes will restart the container. Readiness probes check if a container is ready to accept traffic.

How do I configure these probes in my deployment?

You can configure probes in your deployment YAML file under the spec section. For example, you can specify the httpGet or exec commands for the probes.

Can you give me an example of a YAML configuration for both probes?

Sure! Here's a simple example:

livenessProbe:
  httpGet:
    path: /healthz
    port: 8080
readinessProbe:
  httpGet:
    path: /ready
    port: 8080
