Why Docker Matters

I recently started learning Docker and wanted to understand how it works behind the scenes—the Docker Engine, container isolation, and its usefulness in development and deployment. One thing I quickly realized is how helpful Docker is for maintaining a consistent environment. No matter where you run it, things behave the same, and that stability is crucial, especially during deployment.

Solving OpenSUSE Pain Points

Docker solved one of my biggest pain points. I use Linux, specifically openSUSE. A few months ago I even posted about PostgreSQL installation issues because many packages don’t properly support openSUSE, which was frustrating. With a single Docker command, I can run PostgreSQL—or almost any database—without worrying about OS‑level issues. That single capability made me love Docker even more.

Learning Experience

For me, learning Docker wasn’t very difficult because I was already familiar with virtual machines. Containers feel similar to VMs, but they are much more lightweight, resource‑efficient, and practical for daily development. I’m still learning, but I’m honestly enjoying the process a lot.
