How to pass vm_name to script-local provisioner?

[Andreas Sommer]

{

"type": "shell-local",

"command": "env vm_name={{user `vm_name`}} ./packer/scripts/do-something-with-name.sh",

}

This won't work because it's not a user variable. Since I have several builders (different hypervisors to choose from), the name might differ between them. Is it possible somehow to pass the builder-specific vm_name value to a provisioner?

Best,

Andreas

That is for shell. For shell-local, those environment variables are undefined.

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;;

what I suggest you can do within your wrapper script is to have 2 arguments defined 

1) The Builder type

2) An Extra argument added to the VM name based on the builder chosen by the user who executes the wrapper script

Something like 

 "nameVm": "`echo $_HN`-`echo $_BUILDTYPE`" 

so the final outcome will be a text like

ServerName1-AWS

ServerName1-VMWare

ServerName1-Azure

I guess this goes as far as the imagination and the scripts skills can go..
