Description

This role configures a docker container running Grafana as a metrics dashboard.

It connects to a configured instance of Prometheus or Cortex to query for metrics.

Configuration

The main settings that matter are:

grafana_domain: 'grafana.example.org'
grafana_version: '7.3.4'
grafana_prometheus_sources:
  - { name: 'node-01', addr: '1.1.1.1', port: 8080 }
  - { name: 'node-02', addr: '1.1.1.2', port: 8080, path: 'proxy/' }

You should also configure OAuth:

grafana_oauth_id: '123qwe123qwe123'
grafana_oauth_secret: 'qweasdqweasdqweasdqweasd

Optional email configuration might be useful:

grafana_smtp_enabled: true
grafana_smtp_from_addr: 'grafana@example.org'
grafana_smtp_from_name: 'Grafana Email'
grafana_smtp_host: 'smtp'.example.org
grafana_smtp_port: 587
grafana_smtp_user: 'grafana'
grafana_smtp_pass: 'super-secret-password'

You can optionally allow anonymous access:

grafana_anonymous: true

Details

Configuration consists of two templates:

• grafana.ini.j2 - Grafana main configuration file.
• prometheus.yml.j2 - Initial configuration of the query backend(s).
