1. Install dependencies

   pip install ansible
   
   # For local installs
   sudo apt install -y sshpass

2. Create a file called vars.yml that looks like

   passwords:
       grafana_admin_username: 123
       grafana_admin: 123

3. Generate keys

   cd files
   openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem

4. Run the Ansible playbook to provision the machine

   ansible-playbook -i <ssh remote>, install.yml --extra-vars=@vars.yml
   
   # For local installs
   ansible-playbook -i <ssh remote>, install.yml --extra-vars=@vars.yml -kK

Debugging

# see why containers aren't up
sudo docker stack ps monitoring --no-trunc

# see grafana logs
sudo docker service logs monitoring_grafana --raw

# log into a container
sudo docker ps  # get id
sudo docker exec -it <ID> /bin/bash
