Template not saving parameter context assignment
Hi,
I have a flow that uses parameter contexts. I understand that the parameter
context definitions themselves are persisted to flow.xml.gz.
However, when I save my flow as a template, delete the flow from the canvas,
then add the template back onto a blank canvas, all of the processor context
assignments I made are gone. When I download and search the template file
itself, there's no reference to the parameter context assignments.
So, where are the assignments stored? And how would I go about deploying
this template to many servers without someone having to manually go back
into the flow on each server and adding the assignments all over the place?
We don't use NiFi Registry; we use a traditional Maven based deployment
cycle.
TIA!

Re: Template not saving parameter context assignment
Posted by Andy LoPresto <al...@apache.org>.
Parameter contexts were added after the use of templates was no longer recommended and substantially deprecated and NiFi Registry was selected as the managed flow definition version control and environment promotion system. There are future efforts to facilitate the export/import of flow segments directly to/from a NiFi instance without NiFi Registry but they are not released yet.
