Here's what I am trying to achieve it.
*dynamic "storage" { *
* for_each = var.storage *
* content { *
* disk_size = storage.key disk_thin_provisioned = true }*
*}*
and storage is defined as list variable in variables.pkr.hcl
*variable "storage" { default = [] }*
Running Packer like this:
packer build -var ks-file='"ks-2disk.cf"' -var
storage='"["51200","25600"]"' .
Getting this error at this time: Error: Extra characters after expression
on line 1: (source code not available)
An expression was successfully parsed, but extra characters were found
after it.
