Demo repository with Prometheus and a simple Flask application

Getting Started

Clone the project, add an entry to ansible/files/htpasswd, and start the VM via Vagrant.

Starting the VM

cd prometheus-demo-app
htpasswd -c ansible/files/htpasswd admin
vagrant up

Running the setup on Digital Ocean

1. Get an API key via DO web interface
2. Get your SSH key ID (if you don't have one associated with your account, add it via the DO web interface)

curl -X GET -H 'Content-Type: application/json' -H 'Authorization: Bearer $TOKEN' "https://api.digitalocean.com/v2/account/keys"

3. Fill in the do_api_key and do_ssh_key_id variables in ansible/droplet.yml
4. Run the droplet creation playbook

cd ansible
ansible-playbook -i do-inventory droplet.yml

5. Get the IP address of the droplet (shown at the end of the playbook run)
6. Add a user to the ansible/files/htpasswd file so you can log into Prometheus

htpasswd -c ansible/files/htpasswd admin

7. Run the Prometheus playbook

ansible-playbook -i '$DOIPADDRESS,' -u root prometheus.yml

8. Check the web interface, NGINX should be running on ports 80 and 443 (HTTPS uses self-signed certificate)
9. (Optional) if used in combination with flask-demo-app, update the prom_target_host variable in ansible/prometheus.yml to point to your app
