Whatsupdocker is great for these. You can configure it from docker compose labels and set regex for version matching which is very usefull, you can also use mqtt and ntfy to have notifications in homeassistant and on your computers or phone.

You wanted to find out from those who ALSO run hosting servers in actual data centers what is their hosting panel in reddits selfhosted community?

With your higher intellect you should agree with me that you are an IDIOT ;)

I have two wireguard servers and a reverse proxy (Traefik).

I have setup my services so that they are only accessible from one wireguard VPN. No matter i am on LAN or WAN.

Second wireguard server is to connect to different vpn networks that i usually need to push some code or access the dev or prod servers for my projects. I have build wg-easy manually to install many vpn clients within it’s image and configure routes so that they work without problems simultaniously. It all works GREAT. Openvpn, Openconnect, pptp and barracuda VPN.

I had this setup on my router but i was given this barracuda vpn client which can’t work on devices except X86. Sadly my router is not x86 and i just moved everything and installed all these vpn clients with that barracyda vpn client inside docker container with wg-easy.

I run about 30 stacks (about 60 containers) on my 1L mini pc with i5 8500T + 12 GB RAM. If i were to split them in their own VMs it would be impossible to do. I would have run out of resources probably on fourth VM :D. 5.8 GB RAM is free on idle and i also have ZRAM enabled. I work on it too i have code-server and cloudbeaver running on it. I never run out of memory. Although i am thinking to upgrade it to 16 GBs. I know RAM IS CHEAP but i do not need more then 16 GBs on this PC.

This setup also does not need to be so complex. I have stacks in their own networks isolated and access them solely from wireguard VPN no matter where i am on LAN or connecting from WAN. Wireguard is always on on my laptop and phone.
