You dont need or want docker on your vm host. But a bare metal docker host can solve many peoples needs.

Dont listen to them! The main issue with containers vs vm is security as you lxc runs in the hosts, while a vm runs on the host.

Use what you are familiar with and remember that lxc are containers and docker are containers, but the use of them are vastly different.

Because a lot of people don’t learn docker, they install docker because some software they want to use is distributed that way.

But aside from buying a real truck instead of a typhoon, intels memory support might not be hard limit. It probaly is but it might not be.

More likely the mb’s memory controller can handle 256gb so if a new processor comes along with support for 256gb it will work.

If i was considering one server with 256gb ram i would go for server hardware and not try to use consumer stuff.

I switched to caddy just for the certs. I get trusted certs on all my internal subdomains without maintenance.

I use haproxy, nginx and caddy at work including a caddy instance with internal CA. 4 lines in config and its signed by our normal CA, so its trusted by all our devices.

Without a 3rd they can get confused if they loose contact but both nodes are up. Like both are in charge as one vote is enough

So 3+ hosts for clustering or 2 hosts and an qdevice to fake it
