Deploy a CouchDB cluster to Digital Ocean via Terraform

Create a three node cluster with a front end load balancer. Configure as a CouchDB cluster.

Partly based on this tutorial: How To Use Terraform with DigitalOcean.

Configuration

export DO_PAT="digital ocean personal access token"
export COUCHDB_PASSWORD="secret admin password"
export COUCHDB_SECRET="cookie secret"

I created a new SSH key in the current directory using ssh-keygen but you could also use an existing key in the path below. DO needs to know about this key.

Build the cluster

To validate the configuration and view the plan:

terraform plan \
  -var "do_token=${DO_PAT}" \
  -var "pvt_key=./id_rsa" \
  -var "couchdb_password=${COUCHDB_PASSWORD}" \
  -var "couchdb_secret=${COUCHDB_SECRET}"

To create the cluster substitute terraform apply.
