This is a continuation of my other post

I now have homeassistant, immich, and authentik docker containers exposed to the open internet. Homeassistant has built in 2FA and authentik is being used as the authentication for immich which supports 2FA. I went ahead and blocked connections from every country except for my own via cloudlfare (I'm aware this does almost nothing but I feel better about it).

At the moment, if my machine became compromised, I wouldn't know. How do I monitor these docker containers? What's a good way to block IPs based on failed login attempts? Is there a tool that could alert me if my machine was compromised? Any recommendations?

EDIT: Oh, and if you have any recommendations for settings I should change in the cloudflare dashboard, that would be great too; there's a ton of options in there and a lot of them are defaulted to "off"

The entire point of selfhost is to host private services not available to the public. By literal definition, that's allowing only local traffic to connect to your services. It's infinitely more secure. A VPN allows you to extend those services over the clearnet to authorized devices via virtualized networks. You don't have to worry about messing with inbound/outbound ports, or worrying about software failure or misconfigurations accidentally exposing you to the clearnet. You don't have to worry about DDoS, or abuse. Being attacked? Bring down your VPN and that completely shuts down your issue. Your network is completely unreachable by anyone but a local host.

There's simply no room for an argument. VPN is objectively better in all possible situations.

Probably your entire point, a lot of self hosters self host services that family members and friends can reach most of the time without the need of a VPN. This very community is full of examples.

It’s infinitely more secure

I'm with you about that.

There’s simply no room for an argument.

As stated in the other post, I'm sorry about that, I'm here to discuss and learn, if you don't have room for an argument, our discussion ends here.

VPN is objectively better in all possible situations.

Exactly! in all possible situation!!!

I didn't know that was the entire point of self hosting. Some people want to self host things for the public, like a website or game server.

There is a program called "yunohost" to simplify this process.

Maybe a VPS is better for website hosting but some people want to self host.
