Probes in Kubernetes with Hands-on

In the Kubernetes Architecture chapter of this series, we’ve learned that a pod is restarted automatically if Kubernetes finds a pod in an unhealthy state. But how does Kubernetes knows if a pod is healthy or not? In this section, we’ll learn how K8s identifies whether a pod is working or not, and also we’ll learn how we can customize this behavior using Probes with complete Hands-on. We'll learn about 3 different types of Probes that Kubernetes provides:
1. Startup Probe
2. Liveness Probe
3. Readiness Probe

Thanks Pavan. Nice Video and great explanation like other videos. One question, you gave all 4 parameters same vaue for al probes. what is the best values of each parameter for each probe (start up probe is optional)
simple application like spring boot which starts in 15seconds

As I have seen in multiple places if both in Liveness and startUp probe if we fail the last attempt then POD will stopped? But you have mentioned in the liveness probe last attempted failed pod will restart again. Which is correct ?

HI Pavan, I have one question from Probes, when liveness probe fails, 3 pods got restarted but when readiness probe fails, only one pod connection got disconnected from services.... why it is like ?

[@PavanElthepu]

It’s deployment or statefulset?
