From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I strongly suggest that you install portainer if this is your first time playing with docker.
It'll make your life and learning curve dramatically easier.
I'm not suggesting you dont learn how to do it all over CLI (I actually think CLI is way easier and faster to deploy once you get the hang of it), but if you're looking to deploy something right away, I believe portainer is your best bet.
This. I had the same issue, and just about every tutorial focuses on the command line, and I get why... It's way more powerful and actually becomes the standard that people who are using docker repeatedly would need to learn.
That being said, this was my first foray into containerizing things since VMware became a thing. So I needed a UI that felt familiar and helped me understand some of the Dockers specific settings and configurations. This was a godsend in helping me get things up and running, and then later I had to learn how to do it properly with docker compose.
For what it's worth, I still keep my portainer instance running, and use it for some administration stuff like resets, but I think it helps smooth my learning curve. Docker via the command line exclusively pretty much requires you to understand all of the notions and concepts involved.
That's exactly right. I run UnRaid as my NAS, and not a single docker has been installed from their app store. I also still have Portainer running (at this point I have no idea why anymore, since I haven't used it in over a year) and it barely uses any resources. Portainer was my first shot at docker containers, and I'll always be grateful to the developers. I doubt I would have continued learning Docker if Portainer had not existed.
