Terraform Digitalocean Droplet

Provides a DigitalOcean Block Storage volume which can be attached to a Droplet in order to provide expanded storage

We eat, drink, sleep and most importantly love DevOps. We are working towards strategies for standardizing architecture while ensuring security for the infrastructure. We are strong believer of the philosophy Bigger problems are always solved by breaking them into smaller manageable problems. Resonating with microservices architecture, it is considered best-practice to run database, cluster, storage in smaller connected yet manageable pieces within the infrastructure.

This module is basically combination of Terraform open source and includes automatation tests and examples. It also helps to create and improve your infrastructure with minimalistic code instead of maintaining the whole infrastructure code yourself.

We have fifty plus terraform modules. A few of them are comepleted and are available for open source usage while a few others are in progress.

Prerequisites

This module has a few dependencies:

• Terraform 0.15
• Go
• github.com/stretchr/testify/assert
• github.com/gruntwork-io/terratest/modules/terraform

Examples

IMPORTANT: Since the master branch used in source varies based on new modifications, we suggest that you use the release versions here.

Simple Example

Here is an example of how you can use this module in your inventory structure:

    module "droplet" {
      source             = "terraform-do-modules/droplet/digitalocean"
      version            = "0.15.0"
      name               = "droplet"
      environment        = "test"
      label_order        = ["environment", "name"]
      droplet_count      = 1
      region             = "bangalore-1"
      ssh_keys           =  [module.ssh_key.fingerprint]
      vpc_uuid           = module.vpc.id
      droplet_size       = "nano"
      monitoring         = false
      private_networking = true
      ipv6               = false
      floating_ip        = true
      block_storage_size = 5
      user_data          = file("user-data.sh")
    }

Inputs

Name	Description	Type	Default	Required
application	Application (e.g. cd or clouddrove).	string	""	no
backups	Boolean controlling if backups are made. Defaults to false.	bool	false	no
block_storage_filesystem_label	Initial filesystem label for the block storage volume.	string	"data"	no
block_storage_filesystem_type	Initial filesystem type (xfs or ext4) for the block storage volume.	string	"xfs"	no
block_storage_size	(Required) The size of the block storage volume in GiB. If updated, can only be expanded.	number	0	no
createdby	CreatedBy, eg 'terraform'.	string	"terraform"	no
custom_image	Whether the image is custom or not (an official image)	bool	false	no
delimiter	Delimiter to be used between organization, environment, name and attributes.	string	"-"	no
droplet_count	The number of droplets / other resources to create	number	1	no
droplet_enabled	Flag to control the droplet creation.	bool	true	no
droplet_size	the size slug of a droplet size	string	"micro"	no
environment	Environment (e.g. prod, dev, staging).	string	""	no
floating_ip	(Optional) Boolean to control whether floating IPs should be created.	bool	false	no
floating_ip_assign	(Optional) Boolean controlling whether floatin IPs should be assigned to instances with Terraform.	bool	true	no
floating_ip_count	Number of floating IPs to create.	string	""	no
image_id	The id of an image to use.	string	""	no
image_name	The image name or slug to lookup.	string	"ubuntu-18-04-x64"	no
ipv6	(Optional) Boolean controlling if IPv6 is enabled. Defaults to false.	bool	false	no
label_order	Label order, e.g. name,application.	list	[]	no

name	Name (e.g. app or cluster).	string	""	no
private_networking	(Optional) Boolean controlling if private networks are enabled. Defaults to false.	bool	false	no
region	The region to create VPC, like london-1 , bangalore-1 ,newyork-3 toronto-1.	string	"bangalore-1"	no
resize_disk	(Optional) Boolean controlling whether to increase the disk size when resizing a Droplet. It defaults to true. When set to false, only the Droplet's RAM and CPU will be resized. Increasing a Droplet's disk size is a permanent change. Increasing only RAM and CPU is reversible.	bool	true	no
ssh_keys	(Optional) A list of SSH IDs or fingerprints to enable in the format [12345, 123456]. To retrieve this info, use a tool such as curl with the DigitalOcean API, to retrieve them.	list	[]	no

vpc_uuid	The ID of the VPC where the Droplet will be located.	string	""	no

Outputs

Name	Description
id	The ID of the Droplet.
name	The name of the Droplet.
urn	The uniform resource name of the Droplet.

Testing

In this module testing is performed with terratest and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a GO environment in your system.

You need to run the following command in the testing folder:

  go test -run Test
