RE: docker-compose: the version does matter

Small workplace story here... I think it's relatable :^)

So, we also use Docker at work. After all, who doesn't like the idea of deploying containers? That being said, no one here really bothers about the version. Probably it's out of pure fear on breaking things when upgrading, or no one just has the time for that... anyway, some of our stuff are old. That includes Docker.

And how old are we talking about... let's just say that when we try to finally use Docker Compose to deploy one of the new fancy ideas we had, all the commands online didn't worked. The Docker we had simply refused to recognize it as an extension despite we threw it into the correct directory. We had to add docker-compose the binary to PATH, then run docker-compose instead of docker compose.

It still functions, I don't know how (perhaps by pure luck...), but yeah, versions do matter. Compatibility only works till an extent.
