# template\_cloudinit\_config

Renders a multi-part cloud-init config from source files.

## Example Usage

```
# Render a part using a `template_file`
data "template_file" "script" {
  template = "${file("${path.module}/init.tpl")}"

  vars {
    consul_address = "${aws_instance.consul.private_ip}"
  }
}

# Render a multi-part cloudinit config making use of the part
# above, and other source files
data "template_cloudinit_config" "config" {
  gzip          = true
  base64_encode = true

  # Setup hello world script to be called by the cloud-config
  part {
    filename     = "init.cfg"
    content_type = "text/part-handler"
    content      = "${data.template_file.script.rendered}"
  }

  part {
    content_type = "text/x-shellscript"
    content      = "baz"
  }

  part {
    content_type = "text/x-shellscript"
    content      = "ffbaz"
  }
}

# Start an AWS instance with the cloudinit config as user data
resource "aws_instance" "web" {
  ami           = "ami-d05e75b8"
  instance_type = "t2.micro"
  user_data     = "${data.template_cloudinit_config.config.rendered}"
}
```
