What I did is create a wrapper script that takes the name as an argument
and then I create dynamically the JSON file passing this variable to the
JSON file as a user Variable..
Something like
This is my usage Function from the wrapper script
usage() {
echo -e "
Usage: $(basename $0) -i <IP ADDRESS> -n <SERVER NETMASK> -g <SERVER
GATEWAY> *-s <SERVER HOSTNAME>* [ -d|-h|-v|-t <SERVER TYPE|-f <BULK SERVER
LIST> ]
and This is where I dynamically create the JSON file
*create_json_template () {*
cat > $_JSONFILE << __EOF
{
"_comment": "This si a centos7-x64 Machine for VmWare ESXi 6.0",
"variables": {
* "nameVm": "`echo $_HN`-centos-7.1-vmware",*
Here is where I define the variable name from the options passed to the
script
if [[ $# != 0 ]];then
while getopts ":i:n:g:s:t:f:dvh" Option
do
case $Option in
i ) _IP=$OPTARG;;
n ) _NM=$OPTARG;;
g ) _GW=$OPTARG;;
* s ) _HN=$OPTARG;;*
