Infrastructure

This repo contains infrastructure as code for cow network.

Requirements

• Have Terraform (>= 0.14.8) installed
• Have Python3 installed
• Have Pipenv installed

Usage

Setup

• Run ./setup.sh to set up your local repo.
• Set $COW_NET_SSH_KEY to your personal SSH key (Recommendation: Install direnv and load it automatically)
• Create tf/token.auto.tfvars file and put in your hcloud API token like this hcloud_token = "<mytoken>"

Note: Always make sure you are in your virtual environment, if not execute pipenv shell otherwise all python modules will be missing.

Initial server setup

When deploying the infrastructure from scratch, you have to use a SSH key we call management-key which functions basically as a bootstrap key. Add other SSH keys using this command:

$ ansible-playbook --private-key <management-key> add_ssh_keys_playbook.yaml -e servers=<groups>

The management key has to be set on all hcloud servers.
