I know the desktop, and mobile apps work without https, however I can’t remember if you can set it up via those apps?

I ran vaultwarden for a couple of years without q certificate, I just couldn’t log into my instance via the browser.

Start off small, get an old PC that has an i5or better that’s got vt-d support. start off with 8gb of RAM or more. Then throw proxmox on it and you are off to the races. It will save you a lot of money since you can run multiple virtual machines or lxc containers. This is how I started out, my proxmox host now has 26gb of RAM and its running very smoothly . i like opnsense as a router and firewall but its a little advanced but amazing, also get an access point and a switch and you can start building your network. You could also even run opnsense in a VM but that gets a little confusing but its an option.

Ah yeah I’m trying to move to podman for NPM and the access lists don’t work for some reason. On docker though it works very well

I’m running cloudflare and NPM, I did a DNS challenge to get my wildcard cert, then put in access lists so for my internal hosts only private IP address subnet can access them. I have my OPNsense firewall also redirect any of those internal hosts request back to my NPM host. I have everything internal with a valid https cert.

I’m actually in the process of switching over from docker to podman. Its definitely a learning curve, ie. Setting up systems integration etc.

I do love it but its been a bit of a pain, for instance I’m still trying to figure out the errors I’m getting when trying to deploy my matrix and vikunja containers, I’m getting permission errors and can’t find dB errors. I k ow little about podman right now but I would definitely recommend it since it is open source and runs rootless by deafult.
