docker rate limit hit on first time through k8s-api-fundamentals

[csams]

In which scenario did this bug occur?
https://learn.openshift.com/operatorframework/k8s-api-fundamentals/

At what step of the scenario did this happen?
When creating the replicaset in step 3.

Describe the bug
Even though it was my first time through the scenario, I hit the docker rate limit and could not pull the image for the containers. I assume this issue depends on how many others have gone through this or other scenarios that use the image within the rate limiting window.

Logs or error messages
"Failed to pull image "openshiftkatacoda/blog-django-py": rpc error: code = Unknown desc = Error reading manifest latest in docker.io/openshiftkatacoda/blog-django-py: toomanyrequests: You have reached your pull rate limit.
