HASSIO (Home Assistant Supervised) for Synology DSM 7 (Unsupported Installation but allows updates and fully functional)

docker-compose.yaml

version: '3'

services:
    hassio:
        image: homeassistant/amd64-hassio-supervisor
        container_name: hassio_supervisor
        privileged: true
        security_opt:
            - seccomp:unconfined
            - apparmor:unconfined
        environment:
            - HOMEASSISTANT_REPOSITORY=homeassistant/qemux86-64-homeassistant
            - SUPERVISOR_SHARE=/PATH/TO/FOLDER/A
            - SUPERVISOR_NAME=hassio_supervisor
        volumes:
            - /PATH/TO/FOLDER/A:/data
            - /var/run/docker.sock:/var/run/docker.sock
            - /var/run/dbus:/var/run/dbus

To refresh installation docker-compose down then docker-compose up --detach. Supervisor will not remove containers on docker-compose down. Use: docker rm $(docker stop $(docker ps --filter name=hassio* -q)) docker rm $(docker stop $(docker ps --filter name=homeassistant -q))
