Install Ubuntu in Docker container

Using Docker Compose, 

version: "2"
services:
  ubuntu:
    image: ubuntu
    container_name: ubuntu
    environment:
      - PUID=1001
      - PGID=1001
      - PST=America/Los Angeles
    volumes:
      - /your/local/directory/location:/home
    ports:
      - 8096:80
    restart: always
    command: "tail -f /dev/null"

That bottom "command" flag is important to keep the container running.
