Add healthcheck in Dockerfile or document it in the compose.yml

[3DJupp]

Would it be possible to have a health check in place?
Either something thats listening on a certain port:
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 CMD curl -f http://localhost:3000/health || exit 1
Or answering a CMD/CMD-SHELL:
HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 CMD node /app/healthcheck.js

Thanks for this great project, I like it ❤️

Hi @3DJupp

Would you consider that it's healthy if the printer is not reachable ?
