Deploy ESXi virtual machines

deploy_vm.sh

#!/bin/sh

# DESCRIPTION:
# this script will create a virtual machine on an ESXi 6+ hypervisor.
# it will create a small vm to specification from the vmx template config.
# it will create a small thin provisioned disk with 8G as OS drive.
# it will mount an ISO image and have the cdrom ready for install.
#
# pre-reqs: this script needs to be in the root-path of the vmfs datastore where you want to deploy vms.
# pre-reqs: this script needs to have the cwd changed to basedir of this script.
#

# USAGE:
# ./deploy_vms [vm name]
#

# TODO:
# extract basedir from the script source -- prefix basedir to paths in script below.
# make configuration parameters into script arguments. 

# configuration parameters
VM_NAME="$1" # please no spaces

# check if folder already exists
