I have a single Dell R210ii running proxmox and a bunch of VM's and containers.
Opnsense (VM) Home assistant (VM) Technitium DNS (LXC) Ubuntu/OpenVPN (VM) Ubuntu/docker (VM)
Then a splattering of containers in docker. Using portioner as a UI and Authentik for Single sign on.
Plenty of docker containers but these change over time as I try things out. General setup of firewall/DNS/vpn/home assistant & docker host is how it's been for ~2 years now and its done me well.
Toyota Previa!!!
Growing up my family had one of these. Still remember how much space it had inside, little passage way between the driver and passenger seat!
