Issues pulling images with podman

I am working through lab exercise for Kubernetes and Containers and keep on getting the following message when I try to pull image.

podman run --name mysql-basic -e MYSQL_USER=user1 -e MYSQL_PASSWORD=mypa55 -e MYSQL_DATABASE=items -e MYSQL_ROOT_PASSWORD=rootpa55 -d registry.redhat.io/rhel/mysql-80:1
