Issues when Installing Dockers on Rocky Linux 8.10

I was installing dockers on Rocky Linux 8.10. These were my steps:

dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
dnf install docker-ce docker-ce-cli containerd.io

I immediately got this error…..

Error: 
 Problem 1: problem with installed package podman-4:4.9.4-1.module+el8.10.0+1815+5fe7415e.x86_64
  - package podman-4:4.9.4-1.module+el8.10.0+1815+5fe7415e.x86_64 from @System requires runc >= 1.0.0-57, but none of the providers can be installed

To resolve the issues, do add the --allowerasing flag,

dnf install docker-ce docker-ce-cli containerd.io --allowerasing

Working around Docker’s download limit on RedHat OpenShift

Taken from “How to work around Docker’s new download rate limit on Red Hat OpenShift” from RedHat Developer.

Docker recently changed its policy for downloading images as an anonymous user. The company now has a limit of 100 downloads every six hours from a single IP address.

If you are using the OpenShift Developer Sandbox to experiment with a free OpenShift cluster, you might encounter the error message shown in Figure 1.

All you have to do to avoid Docker’s new rate-limit error is authenticate to your Docker Hub account. After you’ve authenticated to the account, you won’t be pulling the image as an anonymous user but as an authenticated user. The image download will count against your personal limit of 200 downloads per six hours instead of the 100 downloads shared across all anonymous cluster users.

For the complete article, do take a look at “How to work around Docker’s new download rate limit on Red Hat OpenShift” from RedHat Developer.
