Secure Way to Expose Docker Containers to the Internet? (lemmy.one)

I've been researching different ways to expose Docker containers to the internet. I have three services I want to expose: Jellyfin, Omnivore (Read-it-later app), and Overseerr.

I've come across lots of suggestions, like using Nginx with Cloudflared, but some people mention that streaming media goes against Cloudflared tunnel TOS, and instead recommend Tailscale, or Traefik, or setting up a WireGuard VPN, or using Nginx with a WireGuard VPN.

The amount of conflicting advice has left me confused. So, what would be the best approach to securely expose these containers?

What I was referring to is called a Bind Mount, where host directories are exposed to the docker container. You may be fine if it's an external hard drive. I use bind mounts because they're easier to back up, but I acknowledge they are less safe.

You may be perfectly fine as you are now. My (and others) suggestions are for added security. As it stands, if there's no target on your bind, the only bad traffic you'll get are from bots trying to pick away at your domain and sub domains. Generally they're not a problem. But being extra safe costs nothing but time.
