or run it in a separate stack…
create and enter a directory for it, like ~/rotator
copy to file docker-compose.yml :

services:
  rotctld:
    image: librespace/hamlib:4.0
    user: '999'
    read_only: true
    environment:
      MODEL: "202"
      SERIAL_SPEED: "9600"
      SET_CONF: "min_az=0,max_az=360,min_el=0,max_el=90"
      ROT_FILE: "/dev/rotator"
    ports:
      - '4533:4533'
    device_cgroup_rules:
      - 'c 188:* rwm'
    devices:
      - '/dev/ttyACM0:/dev/rotator'
    restart: 'unless-stopped'
    command: 'rotctld'
    stop_grace_period: 1s

you need to change the line with the device mapping to /dev/rotator, but only on the left side of the colon.
the format is <source>:<target> and only change source.

you can change the MODEL, SERIAL_SPEED and SET_CONF as you like, the ROT_FILE should not be touched.

bring it up with docker compose up -d and down with docker compose down when you don’t need it.
check the logs with docker compose logs -f
and query it with docker compose exec -it rotctld rotctl -m 2 like enter the p command:

Rotator command: p
Azimuth: 179.00
Elevation: 147.00

edit: depending on compose version, you might need to change docker compose to docker-compose
