## Impact

This rule detects whether HEALTHCHECK instructions have been added to Docker container images. These instructions provide a way to check the health of the running container, ensuring that issues are detected and handled promptly, improving the reliability and stability of your containerized applications. Adding HEALTHCHECK instructions to your Dockerfiles follows best practices for Docker container health management.

## How to Fix

To mitigate this issue, add HEALTHCHECK instructions to your Dockerfile. Define a command that will be used to check the health of the container and specify the interval, timeout, and retries for how often the check should be performed.

## Example: \[source,go]

* HEALTHCHECK --interval=30s --timeout=3s --retries=3 CMD curl -f <http://localhost/health> || exit 1

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/appsec-rules/iac-security/compute/appsec-docker-2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
