## Impact

Readiness Probe is a Kubernetes capability that enables teams to make their applications more reliable and robust. This probe regulates under what circumstances the pod should be taken out of the list of service endpoints so that it no longer responds to requests. In defined circumstances the probe can remove the pod from the list of available service endpoints. Using the Readiness Probe ensures teams define what actions need to be taken to prevent failure and ensure recovery in case of unexpected errors. <https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/\\[Kubernetes.io> Documentation]

## How to Fix

*Resource*: Container *Field:* readinessProbe (Optional)

## The probe describes a health check to be performed against a container to determine whether it is ready for traffic or not. Its configurations may include: exec, failureThreshold, httpGet, initialDelaySeconds, periodSeconds, successThreshold, tcpSocket and timeoutSeconds. \[source,go]

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/monitoring/appsec-k8s-9.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
