» linode_stackscript

Provides a Linode StackScript resource. This can be used to create, modify, and delete Linode StackScripts. StackScripts are private or public managed scripts which run within an instance during startup. StackScripts can include variables whose values are specified when the Instance is created.

For more information, see Automate Deployment with StackScripts and the Linode APIv4 docs.

The Linode Guide, Deploy a WordPress Site Using Terraform and Linode StackScripts, shows how a public StackScript can be used to provision a Linode Instance. The guide, Create a Terraform Module, demonstrates StackScript use through a wrapping module.

» Example Usage

The following example shows how one might use this resource to configure a StackScript attached to a Linode Instance. As shown below, StackScripts must begin with a shebang (#!/). The <UDF ...> element provided in the Bash comment block defines a variable whose value is provided when creating the Instance (or disk) using the stackscript_data field.

resource "linode_stackscript" "foo" {
  label = "foo"
  description = "Installs a Package"
  script = <<EOF
#!/bin/bash
# <UDF name="package" label="System Package to Install" example="nginx" default="">
apt-get -q update && apt-get -q -y install $PACKAGE
EOF
  images = ["linode/ubuntu18.04", "linode/ubuntu16.04lts"]
  rev_note = "initial version"
}

resource "linode_instance" "foo" {
  image  = "linode/ubuntu18.04"
  label  = "foo"
  region = "us-east"
  type   = "g6-nanode-1"
  authorized_keys    = ["..."]
  root_pass      = "..."

  stackscript_id = "${linode_stackscript.install-nginx.id}"
  stackscript_data = {
    "package" = "nginx"
  }
}
