Multi line string in variable

[Dean Song]

Hi,

Newbee on Terraform.

Any guide on how to use/store the multi line string in variable in Terraform's var file terraform.tfvars? We're trying to do some test in AWS with Terraform, like "aws_launch_configuration" with a multiline string "user_data".

Or we have to use the json format for the Terraform template?

Sample:

user_data

#description

{

   a: ${var.a}

   b: ${var.b}

}

Thanks,

Dean

Dean,

Do lines spanning multiple newlines not work? They should work. If
not, they'll certainly work in Terraform 0.2 (our new grammar we wrote
accepts them).

Another option is to put that data out in a separate file and use the
`file` function.

Best,
Mitchell

Thanks Mitchell. 

After upgrade to latest 0.1.1 and with the "file" function, I can get the multi line content to the "user_data" var, but seems it didn't get the right value for the variables in the file, like it's still ${var.a}, but not the true value of "a"?

user_data:         "" => "#description\n{\n   a: ${var.a}\n   b: ${var.b}\n}\n"

Thanks,

Dean

Dean,

The `file()` function doesn't currently interpolate. We'll be added an
interpolate() function probably to do this.

Best,
Mitchell
