Configure the Docker pull rate limit on public images.
Create Docker user account and receive higher pull limit. Cortex
Docker enforces a pull rate limit 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
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.
