I started writing articles for system administrators on SELinux over 15 years ago. I originally wrote articles for Red Hat Magazine. Once I had written a couple, I was drawn in. I'm constantly working to get members of my team and contributors to our projects to write articles and share their expertise. As the Faber College slogan says, "Knowledge is good."
I still love to write articles on how to use technology, especially when I get a good response from the readers. I look at these articles as a way to prevent issues and bug reports. They can eliminate direct emails on how to do certain things. Administrators can just "Google" or "Bing" (Do people say that?) how to do something, and one of the articles at Enable Sysadmin comes up, perhaps even written by me.
2020 was a tough year for everyone as we moved to a virtualized world. Sadly, this meant less contact with customers and open source aficionados, which I've really missed.
Luckily, container technologies continued to grow. This article highlights the top 10 articles on containers from Enable Sysadmin. I was thrilled to see several from my team and a couple by me (tooting my own horn).
These articles cover the gamut, from explaining cgroups
to step by step guides to what happens when the rootless containers are launched. They even cover running containers on non-Linux platforms. Hint: they are still Linux containers. There are articles on building container images all the way up to Kubernetes for orchestrating containers.
I hope you enjoy the articles, and I look forward to what we will see in 2021 as containers continue to take over the computing world.
