Anyone using "docker run" instead of "docker compose"? (feddit.it)

For the vast majority of docker images, the documentation only mention a super long and hard to understand "docker run" one liner.

Why nobody is placing an example docker-compose.yml in their documentation? It's so tidy and easy to understand, also much easier to run in the future, just set and forget.

If every image had an yml to just copy, I could get it running in a few seconds, instead I have to decode the line to become an yml

I want to know if it's just me that I'm out of touch and should use "docker run" or it's just that an "one liner" looks much tidier in the docs. Like to say "hey just copy and paste this line to run the container. You don't understand what it does? Who cares"

The worst are the ones that are piping directly from curl to "sudo bash"...

Docker-compose is a orchestration tool that wraps around the inbuilt docker functions that are exposed like "docker run", when teaching people a tool you generally explain the base functions of the tool and then explain wrappers around that tool in terms of the functions you've already learned.

Similarly when you have a standalone container you generally provide the information to get the container running in terms of base docker, not an orchestration tool... unless the container must be used alongside other containers, then orchestration config is often provided.
