# This is an example set of commands that uses Terraform and Ansible to create a testnet on Digital Ocean.

# Prerequisites: terraform, ansible, DigitalOcean API token, ssh-agent running with the same SSH keys added that are set up during terraform
# Optional: GOPATH if you build the app yourself
#export DO_API_TOKEN="<This contains the DigitalOcean API token>"
#export GOPATH="<your go path>"

# Find out TF_VAR_TESTNET_NAME (testnet name)

#Note that SSH Agent needs to be running with SSH keys added or ansible-playbook requires the --private-key option.
