Probes in Kubernetes with Hands-on

Поділитися
Вставка
  • Опубліковано 14 чер 2024
  • 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

    This explaination has made me to understand the probes.
    Now I clearly understood the difference between these 3 probes.

    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 ?
