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?

Lots of great ideas in this thread. It sounds like you prefer Jellyfin, but I always encourage people to consider Plex. Plex is excellent, and even if you prefer the features or interface of Jellyfin, you should never expose any application (Plex, Jellyfin, or otherwise) directly to the Internet. This should be non-negotiable. Plex uniquely solves for external access with the mobile/desktop apps and app.plex.tv by brokering client connections into your network without a NAT/PAT on your router or firewall. Plex also supports Google logins, which means that you can now have 2fa and potentially phishing-resistant 2fa if you secure your Google account with a passkey.

At my company we only expose our applications behind a WAF and firewall, and I see that some folks here have recommended Cloudflare. For those who may not know, it is no longer enough to simply rely on a firewall. When your application is built with components that may become vulnerable over time, it's critical to use a WAF.
