They do encryption at rest too. Really good notes app and it’s cross platform too. Only missing a “web” client for when you want to access your notes on a computer without Joplin installed (but that defeats the purpose of the E2EE IMO)

Run any Linux (I recommend Debian) as a Hyper-V VM, give it a 4-8 gigs of ram, and put all your containers there as you would on an RPi.

Debian usually backports security fixes to older versions, so you may wanna check to Debian if they have an updated version of the package with the security fix.

This can be done by taking the CVE number related to this vulnerability and look at the package changelog.

There is even a tool to convert Docker Run commands to a Docker Compose file :)

Such as this one hosted by Opnxng:

I think Cloudflare DNS works too and it’s free.
