How to provision a new workspace using OSX Azure CLI?

To succeed I had to forgot everything I had read before... and start again with this:

https://azure.microsoft.com/en-us/documentation/articles/power-bi-embedded-iframe/

ON AZURE PORTAL

Create Power BI workspace collection, and get access key (Provisioning)

GET A PBIX

From Power BI Desktop or a sample file

WITH A CLI

(must use that one : https://github.com/Microsoft/PowerBI-Cli )

Create a Power BI workspace

Import .pbix file into the workspace

Get report id

IN MY RAILS APP

(using https://github.com/jwt/ruby-jwt )

Embed the report into the web page

I can't tell about the many bugs encountered, or the signup/login problems with Azure... it was really painful to get there.

Cheers everyone.
