DigitalOcean with Terraform

This installation has only been tested on Ubuntu 22.04.

Other operating systems may work, but are untested.

Step 1. Create admin user

The later executions will require admin privileges.

Create an adminuser first:

sudo adduser adminuser

Add passwordless to adminuser.

First type:

sudo visudo

Then add at the bottom:

adminuser ALL=(ALL) NOPASSWD: ALL

To save and quit in the nano editor:

  1. Press CTRL + O then ENTER to save.
  2. Then press CTRL + X to exit.

Step 2. Download Terraform and Ansible

In the Ubuntu console:

sudo apt update

sudo apt install -y software-properties-common gnupg curl git

sudo add-apt-repository -y --update ppa:ansible/ansible

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -

sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

sudo apt install -y ansible terraform

Step 3. Clone the FreeTAKHub-Installation Git repository

Go to the home directory:

cd ~

git clone https://github.com/FreeTAKTeam/FreeTAKHub-Installation.git

Go to the FreeTAKTeam/FreeTAKHub-Installation directory:

cd FreeTAKTeam/FreeTAKHub-Installation

Step 4. Generate a public/private key pair

For the default, enter (and keep pressing enter):

ssh-keygen

Print out the public key for the next step.

If you did the default, the command will be:

cat ~/.ssh/id_rsa.pub

Step 5. Add your public key to your Digital Ocean project

See: https://docs.digitalocean.com/products/droplets/how-to/add-ssh-keys/to-account/

Step 6. Generate a Digital Ocean Personal Access Token

See: https://docs.digitalocean.com/reference/api/create-personal-access-token/

Step 7. Execute

In the top-level directory of the project, initialize Terraform:

terraform init

Then apply:

terraform apply

You will then be prompted for your DigitalOcean Token and private key path:

var.digitalocean_token
  Enter a value: <DIGITALOCEAN_TOKEN_HERE>

var.private_key_path
  ABSOLUTE path to private key, for example: /home/adminuser/.ssh/id_rsa

  Enter a value: /home/adminuser/.ssh/id_rsa
