Got the ideas from networkchuck

Don't expose anything to the outside world. If you do, use something like Cloudflare tunnels or Tailscale.

Or host a VPN on it and get in through that. Many of these microservices are insecure, and the real risk comes from opening them up to the Internet. This is important.

Also set permissions properly if applicable
