Probe - Kubernetes

liveness Probe:

• Checks if the container is running and healthy.
• Triggers a container restart if the probe fails.
• Focuses on the overall health of the container.

Readiness Probe:

• Determines if the container is ready to handle traffic.
• Temporarily removes the container from service if the probe fails.
• Enables dynamic scaling and smooth service updates without disrupting traffic.

Startup Probe:

• This probe determines whether a container has started or not.

• The startup probe is run only once, after the container has been created, and it will delay the start of the readiness and liveness probes until it succeeds.

• If the startup probe fails, the container is considered to have failed to start and Kubernetes will attempt to restart the container.
