Docker container presenting Graphite and Grafana 2.6. Both applications are configured to store dashboards and similar data into Postgres DB. Postgres DB is not present in the container - it is supposed that additional container with Postgres DB runs aside.
In order to use Grafana you must first log in as an admin and configure the connection to Graphite. Credentials for Grafana are "admin/admin". However any anonymous user is allowed to view Dashboards.
Postgres must be already running. postgres:9.5 container can be used for this purpose.
docker-compose will create entire environment - one container with postgres and another with Graphite&Grafana If you have docker-compose installed, you can clone this repository or download only the docker-composer.yml file and then run:
docker-compose up -d
docker run -d -v /some/location:/var/lib/graphite/whisper -p 80:80 -p 8080:8080 -p 2003:2003 -p 2004:2004 -p 7002:7002 --links db:postgres -e PGHOST=postgres -e PGUSER=pgadmin -e PGPASSWORD=pgadmin ohamada/graphite-grafana
For more information about used environment variables look at section 'Configuration of connection to Postgres'
/some/location - storage of Graphite's RRD data --links db:postgres - optional part, links container 'db' with alias 'postgres' to this container

We suppose that there is a instance of Postgres already running somewhere. In order to configure the container properly you must use environment variables.
