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"

There are so many monitoring tools with various degrees of complicated setup / configuration or the amount of information you get. And honestly, I've looked into various tools: checkmk, monit, Prometheus... And realised that I rarely look into that information anyway. Of all "fancy" tools, I liked the ease of Netdata to set up and the amount of information that you get. However, beware that their in the process to make their free / homelad offering worse. I've been eyeing beszel and don't forget CLI based tools that are avaible such as atop, btop, htop or glances.

If you want to delve deeper into the rabbit hole of monitoring, I can recommend you to read this article below: https://matduggan.com/were-all-doing-metrics-wrong/
