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"...

Plain docker is useful when running some simple containers, or even one-off things. A lot of people thing about containers as long running services, but there's also many containers that are for running essentially a single command to completion and then shuts down.

There's also alternate ways to handle containers, for example Podman is typically used with systemd services as unlike Docker it doesn't work through a persistent daemon, so the configuration goes to a service.

I typically skip the docker-compose for simple containers, and turn to compose for either containers with loads of arguments or multi-container things.

Also switching between Docker and Podman depending on the machine and needs.
