Grafana

Grafana is a metrics visualization software. Picasoft use it to show some stats from our services. This image is basically just a copy of the one from Docker Hub.

Configuration

There are some evironment variable you can use to configure the instance :

• GF_DEFAULT_INSTANCE_NAME : Name of your Grafana instance
• GF_SERVER_ROOT_URL : Root URL of your Grafana instance (eg. https://grafana.picasoft.net)
• GF_SECURITY_ADMIN_USER : Admin user
• GF_SECURITY_ADMIN_PASSWORD : Admin password

Data persistence

In order to ensure data persistence for your Grafana datasources and dashboard, you should mount a volume on /var/lib/grafana. Because Grafana is not execute as root user, you need to specify correct access right to this volume. If using bind mount, you should do something like:

$ mkdir volumes/grafana && chown 472:472 volumes/grafana
