Thanks alvaro it works. But if the key var1 contains "-" it could not
recognize and fails with command not found. I tried to use \ (escape) for
it but the JSON validation fails.
If the key contains (dot) - . also it fails for example if the key contains
test.abc.def it fails. Any workaround to get rid of this issue? I am using
packer 1.0.2.
