Proxmox Node Script

General
1

Hi,

Since I didn’t like inputting all the required commands every time I wanted to push a conferencing node to Proxmox, here’s a little bash script for that. Maybe someone else apart from me finds good use for it :slight_smile:

Currently asks for password for SSH, can be modified to use keys instead.

#!/bin/bash
echo "=== Conferencing Node Deployment to Proxmox ==="

read -rp "Enter Proxmox host (IP or hostname): " PVE_HOST
read -rp "Enter Proxmox SSH username (default: root): " PVE_USER
PVE_USER=${PVE_USER:-root}

read -rp "Enter path to Pexip image (.raw or .vmdk) on this workstation: " IMG_PATH
if [[ ! -f "$IMG_PATH" ]]; then
    echo "ERROR: File $IMG_PATH not found!"
    exit 1
fi

read -rp "Enter new VM ID: " VMID
read -rp "Enter VM name (default: pex-node): " VMNAME
VMNAME=${VMNAME:-pex-node}
read -rp "Enter number of CPU cores (default: 4): " CORES
CORES=${CORES:-4}
read -rp "Enter memory in MB (default: 4096): " MEM
MEM=${MEM:-4096}
read -rp "Enter network bridge (default: vmbr0): " BRIDGE
BRIDGE=${BRIDGE:-vmbr0}
read -rp "Enter Proxmox storage (default: local-lvm): " STORAGE
STORAGE=${STORAGE:-local-lvm}

# Transfer image
echo "Transferring image to Proxmox..."
scp "$IMG_PATH" "${PVE_USER}@${PVE_HOST}:/var/lib/vz/template/"

BASENAME=$(basename "$IMG_PATH")
EXT="${BASENAME##*.}"

read -rp "Start VM immediately after creation? (y/n): " STARTNOW

# Single SSH session with forced TTY
ssh -t -t "${PVE_USER}@${PVE_HOST}" bash <<EOF
set -e
echo "Creating VM $VMID..."
qm create $VMID --name $VMNAME --memory $MEM --cores $CORES --net0 virtio,bridge=$BRIDGE --cpu host

IMGFILE=/var/lib/vz/template/$BASENAME

if [[ "$EXT" == "vmdk" ]]; then
    echo "Converting VMDK to RAW..."
    qemu-img convert -f vmdk -O raw \$IMGFILE /var/lib/vz/template/${BASENAME%.vmdk}.raw
    IMGFILE=/var/lib/vz/template/${BASENAME%.vmdk}.raw
fi

echo "Importing disk into $STORAGE..."
qm importdisk $VMID \$IMGFILE $STORAGE

DISK_ID=\$(pvesm list $STORAGE | grep "vm-${VMID}-disk" | awk '{print \$1}' | tail -n1)
echo "Attaching disk \$DISK_ID..."
qm set $VMID --scsihw virtio-scsi-pci --scsi0 \$DISK_ID
qm set $VMID --boot c --bootdisk scsi0

echo "Cleaning up uploaded images..."
rm -f /var/lib/vz/template/$BASENAME
[[ "$EXT" == "vmdk" ]] && rm -f /var/lib/vz/template/${BASENAME%.vmdk}.raw
echo "Cleanup complete."

if [[ "$STARTNOW" =~ ^[Yy]$ ]]; then
    echo "Starting VM $VMID..."
    qm start $VMID
fi

echo "VM $VMID ($VMNAME) deployed successfully."
