How safe is self-hosting a public website behind Cloudflare? (feddit.uk)

I work in tech and am constantly finding solutions to problems, often on other people's tech blogs, that I think "I should write that down somewhere" and, well, I want to actually start doing that, but I don't want to pay someone else to host it.

I have a Synology NAS, a sweet domain name, and familiarity with both Docker and Cloudflare tunnels. Would I be opening myself up to a world of hurt if I hosted a publicly available website on my NAS using [insert simple blogging platform], in a Docker container and behind some sort of Cloudflare protection?

In theory that's enough levels of protection and isolation but I don't know enough about it to not be paranoid about everything getting popped and providing access to the wider NAS as a whole.

Update: Thanks for the replies, everyone, they've been really helpful and somewhat reassuring. I think I'm going to have a look at Github and Cloudflare's pages as my first port of call for my needs.

I know it's not technically "self" hosted but I'd get a cheap yearly VPS somewhere and run a webserver off of that.For me its worth the peace of mind to keep my network a temple instead of a bus terminal. I paid $13 usd for the year for mine

A VPS makes sense insofar as keeping things thoroughly isolated from my own systems, but the overhead of maintaining a box that's directly connected to the Internet like that isn't something I'm keen on and I'm not convinced I'd have the expertise to do it right from the outset.

Change the ssh port to something with 4-5 digits, disable ssh password Auth and use certificates only, don't expose any port other than ssh and 443.

If you're paranoid, use cloudflare as a proxy and set the VPS firewall to only accept incoming traffic from cloudflares ip list.

That's about it really.

Changing port is security by obscurity and it doesn’t take much time for botnets to scan all of IPV4 space on all ports. See for example the ever updated list that’s available on Shodan.

Disable password login and use certificates as you’ve suggested already, add fail2ban to block random drive-bys, and you’re off to the races.
