Configure Prometheus

The autoscaler publishes and exposes metrics that can be consumed by Prometheus. Please note that access to the metrics endpoint is restricted and requires an authorization token.

First, create a random token:

$ openssl rand -base64 12
  zFuQGzQetpeaSWix

Next, register the token with the autoscaler:

DRONE_PROMETHEUS_TOKEN=zFuQGzQetpeaSWix

Finally, configure the prometheus scraper:

1
2
3
4
5
6
7
8
9

global:
    scrape_interval: 60s

    scrape_configs:
    - job_name: 'autoscaler'
        bearer_token: zFuQGzQetpeaSWix

        static_configs:
        - targets: ['domain.com']
