# Configure Docker pull rate limit

Docker enforces a [pull rate limit](https://www.docker.com/blog/scaling-docker-to-serve-millions-more-developers-network-egress/) on public images. The limit is based on an IP address or as a logged-in Docker hub user. The default limit (100 pulls per 6 hours) is usually high enough for Cortex XSOAR's use of Docker images, but the rate limit may be reached if using a single IP address for a large organization (behind a NAT). If the rate limit is reached, the following error message is issued:

`Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit.`

To increase the limit:

1. Sign up a free user [in the Docker hub](https://hub.docker.com/signup/).

   The pull limit is higher for a registered user (200 pulls per 6 hours).
2. Authenticate the user on the engine machine by running the following command.

   **`sudo -u demisto docker login`**
3. (Optional) Instead of manually logging in to Docker to pull images, you can edit the [Docker config file](https://docs.docker.com/engine/reference/commandline/login/) to use credentials from the file or from a credential store.

# 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 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/cortex-xsoar-8-on-prem/8.9/configure-cortex-xsoar/engines/install-an-engine/docker/install-docker/configure-docker-pull-rate-limit.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.
