docker-simple

The simplest stack. docker-simple launches a single DigitalOcean Droplet, assigns a public IP address, and installs Docker.

Prerequisites

You must have an account with DigitalOcean and generate an API token. You can generate an API token in the console. It is assumed you have an environment variable named $DIGITALOCEAN_TOKEN throughout the rest of this tutorial.

Launching

To launch the stack begin by generating a private/public SSH key. The public key will be will be uploaded to the Droplet and configured as the root user.

ssh-keygen -b 4092 -q -N "" -f private/node.pem

Execute terraform plan to validate your configuration.

terraform plan -var "do_token=$DIGITALOCEAN_TOKEN"

Apply the configuration and launch the Droplet. If all goes well you will see Apply Complete! at the end.

# Apply the configuration
terraform apply -var "do_token=$DIGITALOCEAN_TOKEN"
Apply complete!

Once the stack has been launched you can use Terraform to see the public IP address of the server and connect via SSH.

terraform output

servers = 107.170.20.34

ssh -i private/node.pem root@107.170.20.34
