# This creates a deploy-able plugin zip file in the release directory.
# 
# Installation instructions:
# 1. Determine the Grafana server URL. This may not be the public URL, and are defined in the `server` section
#    of the Settings page or grafana.ini file. For example, the server URL may be http://localhost:3000.
# 2. Run this script with the server URL.
# 3. Copy the zip file to the machine hosting grafana and unzip into the grafana plugins directory 
#    (/var/lib/grafana/plugins on linux).
# 4. Restart grafana.

Usage: $0 -u [root_urls] -k [api_key]

Packages the project as a "private" plugin so it may be used on a grafana server.
The end result is a zip file in the 'release' directory containing the plugin.

Unfortunately, only NeedleInAJayStack can run this since the API key cloud account must match the datasource name.
This is a workaround until the package is approved as a "public" plugin by Grafana.

-u  root_urls:   Comma separated list of root urls for the grafana server.
-k  api_key:     API key for the grafana server.
