How to install docker-compose

Docker-compose is a tool that runs several containers together from one description. What follows is background, not a walkthrough. The authoritative version always lives with the project's own team.

Paths onto a machine

In practice this means one of a handful of routes: an operating system package index, a registry tied to a language, a version manager, or a source tree built with the project's own tooling. Which one applies is decided by the platform and by the maintainers.

Who is behind it

Day-to-day direction belongs to the maintainers. They set the roadmap, cut releases, and decide which platforms stay supported.

First things to confirm

Establish which platforms the current release actually targets. Support ranges shift, and the newest release is frequently not the one suited to an older machine.

If something looks wrong

If the outcome is not what was expected, the cause is nearly always environmental: an earlier copy, a different channel, or a cache that has not been refreshed.

What this domain is

This is a notes-only site. Projects stay with their maintainers; nothing is reproduced here.

Keeping environments clean

Isolating environments, whether with a version manager or per-project directories, removes a whole category of confusing behaviour later on.
