Demo example using Docker Compose for Prometheus tutorials

This example uses a Docker Compose setup to demo the tutorials in the official Prometheus documentation.

To run the demo:

docker compose up -d

Next, you can visit:

• localhost:8090/ping demo app to fire the alert defined in rules.yml.
• Prometheus web ui.
• Grafana, including a provisioned Prometheus datasource and dashboard.
• Alertmanager web ui.

To enable the Alertmanager and receive webhook notifications, you have to configure the webhook URL in the alertmanager.yml file.

receivers:
  - name: webhook_receiver
    webhook_configs:
      - url: '<INSERT-YOUR-WEBHOOK>'
        send_resolved: false

You may use one URL from webhook.site. Then, restart the Docker compose environment and follow the instructions in the Alerting based on metrics tutorial for further details.
