Compose Companion

This is a little CLI tool created for my home server.

It aims to make it easy to configure and document scripts that should run before and/or after the server containers on docker compose go up or down.

Scrips File

The app will read the scripts from a yaml file in the following format:

# compose-companion.yaml

x-before-up:
  sonarr:
    - echo this will run before sonarr startup
    - echo this too will run before sonarr startup, after the previous one
  radarr:
    - echo this will run before radarr startup
    - echo this too will run before radarr startup, after the previous one

x-after-up:
  sonarr:
    - echo this will run after sonarr startup
    - echo this too will run after sonarr startup, after the previous one
  radarr:
    - echo this will run after radarr startup
    - echo this too will run after radarr startup, after the previous one

x-before-down:
  sonarr:
    - echo this will run before sonarr shutdown
    - echo this too will run before sonarr shutdown, after the previous one
  radarr:
    - echo this will run before radarr shutdown
    - echo this too will run before radarr shutdown, after the previous one

x-after-down:
  sonarr:
    - echo this will run after sonarr shutdown
    - echo this too will run after sonarr shutdown, after the previous one
  radarr:
    - echo this will run after radarr shutdown
    - echo this too will run after radarr shutdown, after the previous one

The container keys should match the ones from docker-compose.yaml file.
The app will look for a file named compose-companion.yaml on the folder it's first run, if that's not there it'll ask you to inform the file path manually.
As the top-level keys start with x-, you can use the docker-compose.yaml file itself, if you wish, and these settings will be properly ignored by docker compose.

Commands

For a list of command, run compose --help or simply compose.
For details on each command, run compose [command] --help.
