Yes, of course. Or search for an external reverse proxy. Cloudflare offers something like this. (You set a Cloudflare server IP as target for your domain and then tell Cloudflare your IP and all traffic is routed over the Cloudflare ecosystem so your actual IP is not publicly used.)
I just opened port 443 and forwarded it to my Docker host and have NPM running there, handling all the forwarding to the individual containers, based on the request, but due to my day job I know what I’m doing :)
I would still always be worried it'd been silently bot netted or something if it's accessible, even through cloudflare
I guess cloudflare does a lot to stop attacks from bots though right?
I never tried it personally but I assume you're pretty save.

Does sound pretty reassuring assuming all that works for non http traffic too
I just checked their FAQ. They have information about SSH, SMB, RDP, connecting private networks (VPN), etc. available. I did not dig deeper regarding specific ports, though.
You could always use a reverse proxy on your side just accepting port 443 connections (https) and forwarding to a specific docker container using a specific port without the outside world even knowing.
