How to Deploy Portainer with Podman on Rocky Linux

How to Deploy Portainer with Podman on Rocky Linux

Portainer is a web-based container management platform that makes working with containerized deployments significantly easier, more efficient, and more reliable.

In a previous article, I demonstrated how Warewulf makes it simple to deploy an HPC cluster. Now, I don’t know about you; but, once I have a cluster, I immediately start looking for something to run on it. But I’m a systems guy—not a domain scientist—so that usually means I start benchmarking. Recently at CIQ,...
