Launches a graphite and its webui in a container so we can monitor the cluster.
This should be used as a tool in the srl-roles experiment orchestration framework.
Launch graphite in the container and tell it what to monitor:
docker run \ --name=graphite \ --net=host \ michaelsevilla/graphite
You can fill in STORAGE_SCHEMAS, CARBON, and DASHBOARD environment variables to
append values to the conf files.
