Add Grafana

Grafana is the only service in this tutorial that requires a database. But it comes with an embedded sqlite3 database which can be stored in the filesystem on a mounted volume. So the data can be persisted and we can restart the service at any time without loosing any data.

Add a service

Add the following lines to your docker-compose.yaml to add the grafana service:

  grafana:
    container_name: grafana
    image: grafana/grafana:6.3.5
    depends_on:
      - "prometheus"
    restart: always
    networks:
      - kong-rover-demo
    environment:
      - GF_DATABASE_TYPE=sqlite3
      - GF_DATABASE_PATH=/mnt/data/
    volumes:
      - ./data:/mnt/data
    ports:
      - 3000:3000

Once we started our services we can access Grafana.

Configure service and dashboard

Grafana has a default admin user with username admin and password admin. At first login you will be prompted to set a new password:

Login New Password

Once logged in we can add a new datasource, which connects Grafana to our Prometheus server.

Add datasource

Choose Prometheus as datasource and configure it according to the screenshot.

Select datasource
Datasource configuration

On the left select Dashboards | Manage and then import an existing dashboard.

Navigate to dashboards
Import dashboard

Now configure the dashboard as shown below. After finishing the configuration you will be forwarded to the dashboard.
