This post is written simply for myself to mark the date when I fully decided to ditch Ansible’s containers.podman.podman_containers, and Podman’s nasty port of docker-compose, in favour of Quadlet. Hopefully this page can serve as a useful reference for others considering the same move.
Problems with containers.podman.podman_containers Ansible is great, but it’s a pain if you ssh on to a server, to find a container is down. You then have to jump on to another server to run the playbook to start the container.
I’ve been working at Red Hat for for 13 years, so people will often come to me ask for guidance of where to get started with their Red Hat certification journey. So many people have heard of the RHCE - the Red Hat Certified Engineer exam, which remains one of the most respected IT certifications in the industry, let alone just Linux certifications.
Many of these same people have years of Linux experience, but maybe haven’t taken a Red Hat certification before, or in a long time, and are looking for recommended next steps.
It’s been interesting to witness the meteoric rise of “Docker” over the years, and it is undoubted that the technology that was pioneered and popularized by Docker (more correctly called “Linux Containers”), is here to stay for the long run. The rise of the technology was partially due to the ease of publishing containers, enabled by free DockerHub service. However, in this article, I propose that DockerHub as a single repository of container images is becoming less and less important than it once was, and in it’s place, GitHub is a strong contender to take over as the 1 repository for containers — as it has its sights on being everything a developer needs.
