terraform crash with ec2 instance when trying to use user_data with a map

[solarce]

crash.log from when I tried to launch a new instance, when trying to use user_data with a map

 user_data {
    hostname = "${var.user_data_hostname}"
    fqdn = "${var.user_data_fqdn}"
  }

Thanks, I see you updated the title, is that the new way to get a repro? Can I just set some user data to a map and get this with our without state?

[solarce]

https://gist.github.com/solarce/818f06a0d7564fcd508e should do it

I realize that http://www.terraform.io/docs/providers/aws/r/instance.html#user_data doesn't say it's a map, but I assumed it would be one and I haven't looked at the source code, so if I'm going down the wrong path to use user_data, please do let me know

User data is a string. Tags are a map.

The issue here looks like our validator is not catching the invalid type for user data. Should be easy enough to fix, but haven't looked into it yet.

What should it look like? (Can you tell I haven't used user data much?)

I'm trying to replace passing the following to knife ec2 server

cat /var/lib/rundeck/staging_users.cloud_config
#cloud-config
hostname: @@HOSTNAME@@
fqdn: @@FQDN@@
manage_etc_hosts: true

[mitchellh]

Heh, this should help: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html

Thanks. For completeness sake.

1. I found Unclear how to add user_data to an aws_instance #145, which pointed me at using the file() function
2. The following worked for me

variable

variable "user_data" {
    description = "EC2 instance user data"
}

resource

  # user data for instance
  user_data = "${file(var.user_data)}"

argument
-var user_data=/tmp/instance.cloud_config

[mitchellh]

Fixed crash
