Start an instance

Docker CLI

docker run \
  --name xubuntu \
  --detach \
  --shm-size 2g \
  --publish 3322:3322/tcp \
  --publish 3389:3389/tcp \
  --device /dev/dri:/dev/dri \
  docker.io/hectormolinero/xubuntu:latest

Docker Compose

version: '3.8'
services:
  xubuntu:
    image: 'docker.io/hectormolinero/xubuntu:latest'
    shm_size: '2gb'
    ports:
      - '3322:3322/tcp'
      - '3389:3389/tcp'
    devices:
      - '/dev/dri:/dev/dri'

You will be able to connect to the container via SSH through 3322/tcp port and RDP through 3389/tcp port.

Important: some software (like Firefox) need the shared memory to be increased, if you encounter any problem related to this you may use the --shm-size option.
