Sorry for the response in English. I run several Wordpress websites in Proxmox. I have tried using VM's, LXC containers, and Docker containers. I was successful in all cases. In the end I chose to run each website in its own VM. In my experience It is MUCH easier to backup and/or restore my websites using a VM. If I make a mistake and break something in Wordpress (which is easy for me to do) the process to delete the VM and restore it from a known backup was a lot faster with a VM. I have Proxmox taking backups of my Wordpress VMs every two hours to protect against getting hacked or broken plug-in updates, as well.
I run the website on a VM, I use Cloudflare as my domain registrar, I use cloudflare tunnels (running in a docker container) to expose my sites, and I use the Cloudflare CDN to cache and accelerate my website. Its all free (except the domain name which costs $10 per year) and it works quite well. I love that I have no open firewall ports with the Cloudflare tunnel.
