How to build Proxmox tmpfs image

Once you have a successfully running openQRM Server you can follow the steps below for a Proxmox VE Solution.

These instructions will enable you to proof of concept the Proxmox VE Solution as a tmpfs deployment, however the clustering requires special initialisation. We have developed the ATU Plugin to orchestrate these steps for synchronized cluster initilisation on start and backup configuration on shutdown.

1. Download PVE Kernel - http://download.proxmox.com/debian/dists/buster/pve-no-subscription/binary-amd64/pve-kernel-5.4.114-1-pve_5.4.114-1_amd64.deb
2. Install Kernel
3. Add Kernel to openQRM
   1. (Replace KERNEL_NAME, KERNEL_VER, OPENQRM_UI_USER, OPENQRM_UI_PASS, SERVER_NAME with the appropriate variables) openqrm kernel add -n KERNEL_NAME -v KERNEL_VER -u OPENQRM_UI_USER -p OPENQRM_UI_PASS -l / -i initramfs
   2. openqrm kernel add -n pve-5.4.114-1 -v 5.4.114-1-pve -u OPENQRM_USER -p OPENQRM_PASS -l / -i initramfs
      1. If you are using a self signed cert you may need to load the https call back manually; https://SERVER_NAME/openqrm/base/server/kernel/kernel-action.php?kernel_command=new_kernel&kernel_name=KERNEL_NAME&kernel_version=KERNEL_VER
4. Create Image - To create an image for Proxmox which can be used as a tmpfs image, follow these steps;
   1. apt-get install debootstrap
   2. Create directory mkdir /exports/proxmox_image
   3. debootstrap --arch amd64 buster /exports/proxmox_image/ https://deb.debian.org/debian/
   4. chroot /exports/proxmox_image
   5. apt-get install wget net-tools screen locales collectd
   6. dpkg-reconfigure locales
   7. Follow steps (Start at "Install Proxmox VE") @ https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Buster
   8. If using the ATU Plugin then disable services: pvedaemon, pve-proxy, pve-manager, pve-cluster, cman, corosync, ceph, pvestatd, qemu-server, rrdcached, spiceproxy,
5. Activate NFS Storage (if not already done so)
   1. Under Plugins -> Storage -> NFS-Storage
   2. Add NFS Storage;
   3. name "openqrm-nfs"
   4. Deployment Type: "nfs-deployment"
6. Add NFS Volume (this triggers tmpfs storage)
   1. Under Plugins -> Storage -> NFS-Storage -> Volume Admin -> Edit -> proxmox_image "ADD IMAGE"
7. Tar Image
8. Create NFS Image link to TmpFS image

Optional:

The ATU Plugin is optimised for Proxmox Cluster Deployments and TMPFS Server Configuration Sync Initialise ATU plugin

Create custom FS
