For easiest call 'doc.py' can be just 'doc'

• copy doc file on linux host
• mv doc /usr/local/bin/doc
• chmod +x /usr/local/bin/doc

Also on host must be:

• installed docker
• docker compose file (.yml/.yaml)

Default docker file name - docker-compose-app.yml. Other name must be passed to script

For example, $ cat docker-compose-app.yml

services:
  pg:
    container_name: postgres
    image: postgres:16
  wg:
    container_name: wireguard
    image: lscr.io/linuxserver/wireguard:latest

To pull and up one docker service from file, for example, postgres, commands will be:

• doc pg pull
• doc pg up

This script can be secure management docker, for example here impossible accidentally down all docker services, for this must be passed 'all' explicitly

Also, ls command printed all services and container names from docker compose file

$ doc.py ls
pg
postgres
wg
wireguard

Usage (duplicated in script):

args:
1.docker service name (required for some commands)
        also allowed "all" for control all services in file
2.docker command (required)
        allowed - up,down,pull,start,stop,restart,logs
3.docker compose file (optional)
        default file - docker-compose-app.yml

also there are helpers - ls
