Flynn Cluster on DigitalOcean

DigitalOcean account credentials + this repo = Flynn cluster running on DO

Prerequisites

First, make sure you have terraform, doctl, and ansible installed on your system.

You'll also want to make sure you're authenticated against the DigitalOcean API by running:

doctl auth init

Finally, you'll need to have your default SSH key on hand. To get a list of keys that DigitalOcean knows about, run:

doctl compute ssh-key list

The ID is what we care about here; Terraform will prompt you for it when you deploy.

Now, to create a cluster, just run:

./deploy

This will prompt you for your DigitalOcean API token and your SSH key ID, and spin up a cluster for you with those credentials.

Run deploy -h for usage. You can pass additional args to terraform plan directly on the command line via extra positional args, e.g.:

./deploy -var do_api_token=YOUR_TOKEN

You can also use a Terraform cluster.tfvars file to override these once:

do_api_token = "asdf-qwerty"
public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAA... tamayo@toast"

Then, specify the file on the command line:

./deploy -var-file=cluster.tfvars
