How to setup

Good article - https://medium.com/maxkimambo/proxmox-image-installation-on-hetzner-servers-f5ebbe287f48

Rescue mode installimage Install 'Other' Choose Proxmox Bullseye

Change HOSTNAME to an FQDN if you have one

PART swap swap 32G
PART /boot ext3 512M
PART / ext4 64G
PART /var/data ext4 all

Then check the disk space

root@proxmox ~ # df -h
Filesystem      Size  Used Avail Use% Mounted on
udev             32G     0   32G   0% /dev
tmpfs           6.3G  848K  6.3G   1% /run
/dev/md2         63G  3.1G   57G   6% /
tmpfs            32G   46M   32G   1% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
/dev/md1        485M  176M  284M  39% /boot
/dev/md3        374G   28K  355G   1% /var/data
/dev/fuse       128M   16K  128M   1% /etc/pve
tmpfs           6.3G     0  6.3G   0% /run/user/0

Find the md3 partition which has our space

Unmount it

umount /dev/md3

Create a PV Group

pvcr
vgcreate vg0 /dev/md3
lvcreate -n vms -l 100%FREE vg0
mkfs.ext4 /dev/vg0/vms

Change fstab entry from

UUID=eeabffed-5ecf-4037-a008-8c2d17c9dbed /var/data ext4 defaults 0 0

to

/dev/vg0/vms /var/data ext4 defaults 0 0

We can now go into proxmox, Datacentre, Storage, add Directory, choose our VG0.

This still allows Thin Provisioning when you creata a VM, just be sure to choose QEMU Image Formate (QCOW2) as the disk type.

Then, create a Linux Bridge https://bobcares.com/blog/setup-nat-on-proxmox/

auto vmbr99
#private sub network
iface vmbr99 inet static
    address  10.10.10.1
    netmask  255.255.255.0
    bridge-ports none
    bridge-stp off
    bridge-fd 0

    post-up   echo 1 > /proc/sys/net/ipv4/ip_f
    post-up   iptables -t nat -A POSTROUTING -s '10.10.10.0/24' -o enp0s31f6 -j MASQUERADE
    post-down iptables -t nat -D POSTROUTING -s '10.10.10.0/24' -o enp0s31f6 -j MASQUERADE

    post-up   iptables -t raw -I PREROUTING -i fwbr+ -j CT --zone 1  
    post-down iptables -t raw -D PREROUTING -i fwbr+ -j CT --zone 1

Then do this for port forwarding. This forwards port 8188 to 80 to virtual machine at address 10.10.1.10, assuming your public IP is 213.214.215.216

iptables -t nat -A PREROUTING -p tcp --dport 8188 -j DNAT --to-destination 10.10.1.10:80
iptables -t nat -A POSTROUTING -p tcp --sport 80 -s 10.10.1.10 -j SNAT --to-source 101.102.103.104:8188

Then install Nginx Reverse Proxy. First we need Docker

https://docs.docker.com/engine/install/debian/

Then install Nginx Proxy Manager using docker compose

https://nginxproxymanager.com/guide/

mkdir /root/nginxproxymanager
cd /root/nginxproxymanager
nano docker-compose.yml

Create this file

version: '3'
services:
app:
image: 'jc21/nginx-proxy-manager:latest'
restart: unless-stopped
ports:
- '80:80'
  - '81:81'
  - '443:443'
  volumes:
  - ./data:/data
  - ./letsencrypt:/etc/letsencrypt

Then run it

docker-compose up -d

Add a Proxy Host with https and your public IP and port 8006.

We can now access it directly! Get an ACME cert

Add Websocket support for VNC support.

Add a NAT Network

Thanks to this
