Because it’s “quick start”. Least effort to get a taste of it. For actual deployment I would use compose as well.
Many project also have a example docker-compose.yml in the repository if you dig not so deep into it
There is https://www.composerize.com to convert run command to compose. Works ~80% of the time.
I honestly don’t understand why anyone would make “curl and bash” the officially installation method these days, with docker around. Unless this is the ONLY thing you install on the system, so many things can go wrong.
I used to host composerize. Now I host it-tools which has its own version and many other super helpful tools!
I was going to mention it-tools. It's great!
And if you need more stuff in a similar vein, cyberchef is also pretty neat.
Nice! I wonder if there's anything one has that the other doesn't.
You have changed my life today.
No, the creator of it-tools did. I just told you about it. Give them a star on GitHub and maybe donate if you can ❤️
Out of curiosity, is there much overhead to using docker than installing via curl and bash? I'm guessing there's some redundant layers that docker uses?
Of course, but the amount of overhead completely depends per container. The reason I am willing to accept the -in my experience- very small amount of overhead I typically get is that the repeatability is amazing with docker.
My first server was unRAID (freebsd, not Linux), I setup proxmox (debian with a webui) later. I took my unRAID server down for maintenance but wanted a certain service to stay up. So I copied a backup from unRAID to another server and had the service running in minutes. If it was a package, there is no guarantee that it would have been built for both OSes, both builds were the same version, or they used the same libraries.
My favorite way to extend the above is Docker Compose. I create a folder with a
docker-compose.ymlfile and I can keep EVERYTHING for that service in a single folder. unRAID doesn't use Docker Compose in its webui. So, I try to stick to keeping things in Proxmox for ease of transfer and stuff.Makes sense! I have a bunch of services (plex, radarr, sonarr, gluetun, etc) on my media server on Armbian running as docker containers. The ease of management is just something else! My HC2 doesn't seem to break a sweat running about a dozen containers, so the overhead can't be too bad.
Yeah, that's going to come completely down to the containers you're running and the people who designed them. If the container is built on Alpine Linux, you can pretty much trust that it's going to have barely any overhead. But if a container is built on an Ubuntu Docker image. It will have a bunch of services that probably aren't needed in a typical docker container.
Good point. Most containers I've used do seem to use Alpine as a base. Found this StackOverflow post that compared native vs container performance, and containers fair really well!
It seems like that data is from 2014 as well. I'm sure the numbers would have improved in almost ten years too!
Omg I never knew about composerize or it-tools. This would save me a ton of headaches. Absolutely using this in the future.
