Looking for a way to remote in to K's of raspberry pi's...
now some things you need to think about: - cloud init - this will need to be secure so lock it down hard anything not needed an alternative OS to look at if you have the ability's is https://www.alpinelinux.org/ also as these devices are not that powerfull every extra agent / abstaction layer you add impacts performance need to look at low over head security https://www.crowdsec.net/ and https://github.com/fail2ban/fail2ban (if you call fail2ban security) - using certificates to authenticate ssh login
- Fail2Ban – Daemon to ban hosts that cause multiple authentication errors

Home Lab Setup Recommendations
- Nginx & crowdsec/fail2ban if you are exposing your parts (services) to the public ( https://hub.docker.com/r/baudneo/nginx-proxy-manager, https://www.crowdsec.net, https://www.fail2ban.org )

Firewall rules beyond "deny incoming, enable only the ports that you need"
https://github.com/fail2ban/fail2ban is a mature, easy to set up way to have some dynamic firewall rules that respond to attacks. There are more sophisticated options, but they are probably not worth the return on time investment for you.

Configuring Fail2ban for Traefik Reverse Proxy
I've played a bit with Traefik as reverse proxy and wanted to implement fail2ban for it, after switching from Nginx Proxy Manager. It finally works and successfully bans threat actors that conduct malicous HTTP requests. As soon as a multitude of HTTP errors are detected by fail2ban in Traefik's JSON access logs, the attacker's IP address is banned. I am using a dockerized fail2ban container and ban locally via iptables as well as optionally on Cloudflare, using Cloudflare's API. A ban notification via Telegram can also be configured.

About the roadmap...
However I do not merely rely on this trust. I monitor my systems aggressively. I implement additional security measures to mitigate my exposure and liability. There are systems like fail2ban and login-shield that I use as additional layers (and have audited the code - these systems are a lot simpler than Linux - it's unrealistic for anybody to actually fully-audit the Linux kernel).

How to access Docker containers on home server from public IP?
You need to setup reverse proxy. nginx-proxy-manager, swag. There are also more options like caddy, haproxy etc... You can also setup a VPN and or a service like authelia, fail2ban, crowdsec to restrict access to your site.
What are some alternatives?
