terraform-provider-linode

A plugin for adding a Linode provider.

Description

This is a custom plugin providing a Linode provider for Terraform. This is still a work in progress. It currently only supports managing Linodes currently. In the future dns and nodebalancers will be added. It only supports a subset of the various options that Linode offers. In particular none of the alerting options are supported. They should be easy to add but will likely be tedious.

Requirements

terraform

Installation

Download the plugin from the releases tab Both Linux and FreeBSD binaries are available.
Put it somewhere were it can permanently live, it doesn't need to be in your path.
Create or modify your ~/.terraformrc file. You'll need at least this:

providers {
    linode = "terraform-provider-linode"
}

If you didn't add terraform-provider-linode to your path, you'll need to put the full path to the location of the plugin.

Usage

Provider Configuration

`linode`

provider "linode" {
  key = "$LINODE_API_KEY"
}

The provider options are:

key - (Required) This is your linode api key. It will be read out of the environment variable LINODE_API_KEY.

Resource Configuration

`linode_linode`

resource "linode_linode" "foobar" {
	image = "Ubuntu 14.04 LTS"
	kernel = "Latest 64 bit"
	name = "foobaz"
	group = "integration"
	region = "Dallas, TX, USA"
	size = 1024
	status = "on"
	ip_address = "8.8.8.8"
	private_networking = true
	private_ip_address = "192.168.10.50"
	ssh_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQCxtdizvJzTT38y2oXuoLUXbLUf9V0Jy9KsM0bgIvjUCSEbuLWCXKnWqgBmkv7iTKGZg3fx6JA10hiufdGHD7at5YaRUitGP2mvC2I68AYNZmLCGXh0hYMrrUB01OEXHaYhpSmXIBc9zUdTreL5CvYe3PAYzuBA0/lGFTnNsHosSd+suA4xfJWMr/Fr4/uxrpcy8N8BE16pm4kci5tcMh6rGUGtDEj6aE9k8OI4SRmSZJsNElsu/Z/K4zqCpkW/U06vOnRrE98j3NE07nxVOTqdAMZqopFiMP0MXWvd6XyS2/uKU+COLLc0+hVsgj+dVMTWfy8wZ58OJDsIKk/cI/7yF+GZz89Js+qYx7u9mNhpEgD4UrcRHpitlRgVhA8p6R4oBqb0m/rpKBd2BAFdcty3GIP9CWsARtsCbN6YDLJ1JN3xI34jSGC1ROktVHg27bEEiT5A75w3WJl96BlSo5zJsIZDTWlaqnr26YxNHba4ILdVLKigQtQpf8WFsnB9YzmDdb9K3w9szf5lAkb/SFXw+e+yPS9habkpOncL0oCsgag5wUGCEmZ7wpiY8QgARhuwsQUkxv1aUi/Nn7b7sAkKSkxtBI3LBXZ+vcUxZTH0ut4pe9rbrEed3ktAOF5FafjA1VtarPqqZ+g46xVO9llgpXcl3rVglFtXzTcUy09hGw== btobolaski@Brendans-MacBook-Pro.local"

value	Type	Forces New	Value Type	Description
`image`	Required	yes	string	The image to use when creating the linode. ¹
`kernel`	Required	no	string	The kernel to start the linode with. If you can specify `"Latest 64-bit"` or `"Latest 32-bit"` for the most recent version of either that linode provices
`name`	Optional	no	string	The name of the linode
`group`	Optional	no	string	The group of the linode
`region`	Required	yes	string	The region that the linode will be created in
`size`	Required	yes	int	The amount of ram in the linode plan. i.e. 1024, 2048 or 4096
`ip_address`	Computed	n/a	string	The public ip address
`private_networking`	Optional	sort of	bool	Whether or not to enable private networking. It can be enabled on an existing linode but it can't be disabled.
`private_ip_address`	Computed	n/a	string	If private networking is enabled, it will be populated with the linode's private ip address
`ssh_key`	Required	yes	string	The full text of the public key to add to the root user
`root_password`	Required	yes	string	Unfortunately this is required by the linode api. You'll likely want to modify this on the server during provisioning (which won't force a new linode) and then disable password logins for ssh.
`helper_distro`	Optional	no	bool	Enable the Distro filesystem helper. Corrects fstab and inittab/upstart entries depending on the kernel you're booting. You want this unless you're providing your own kernel.
`manage_private_ip_automatically`	Optional	no	bool	Automatically creates network configuration files for your distro and places them into your filesystem. Will reboot your linode when enabled.

Building

If you're unfamiliar with building go or terraform plugins, please visit the following links first: https://golang.org/pkg/go/build/ https://golang.org/doc/install https://www.terraform.io/guides/writing-custom-terraform-providers.html

Set up your GOPATH. A good default is $HOME/go. You can quickly set it by running export GOPATH=$HOME/go
cd to your new GOPATH.
Run go get github.com/LinodeContent/terraform-provider-linode
cd $GOPATH/src/github.com/LinodeContent/terraform-provider-linode/bin/terraform-provider-linode
go build -o terraform-provider-linode (To cross-compile for freebsd, run GOOS=freebsd GOARCH=amd64 build -o terraform-provider-linode)
Copy the resulting package to wherever you want on your filesystem.
Follow the above instructions for using it.

If you need more information about how to install or use this plugin, do not hesitate to read this article: Using Terraform to Provision Linode Environments

While these technically could be modified, it requires destroying the root volume and creating a new volume which is practically the same as creating a new instance. ↩
