Joseph Witt commented on NIFI-5536:
-----------------------------------

corey

i think we can get there.  the thing is a versioned flow PLUS some instance 
specific details is the recipe needed for deployment.

the mechanisms ive mentioned in this thread are hoe we enable this today.  but 
an even simpler while still secure model is possible and we should strive for 
that.

> NIFI-5489 added EL support to the host, port, virtual host, and user 
> properties of AMQP processors. Not sure why password was not included. We 
> have a use case where sensitive values (passwords) are set as environment 
> variables on our Docker containers and then those variables are referenced by 
> name using EL expressions in our processors and controller services. Flow 
> authors then have no need or means to know what those sensitive values are.
