Automate the Enablement of a StandardHttpContextMap
I'm trying to automate the deployment of a template that contains a HandleHttpRequest processor.
My issue is that this always comes up with an Invalid component marker after a fresh deployment of the template.
The cause of this marker is that the StandardHttpContextMap in the HandleHttpRequest processor needs to be manually enabled in Controller Services.
Is there any way to avoid this manual enablement?

Also meant to say that it can only be enabled if it is valid, meaning
there are no validation messages on the component.
So it might be worth checking in the UI to see if there are any
validation issues on the service.

This is done on purpose since starting and enabling components may cause interactions with external systems, and it may not be clear or desired that just by instantiating the template that all of these interactions are automatically going to take place. So it requires an extra step where the user (or your script) must explicitly enabled and start the components.

If you run it with -verbose does it produce anything more helpful?

RE: Automate the Enablement of a StandardHttpContextMap

Ok I got this working by configuring each Http component's StandardHttpContextMap individual instead having them all ganged all onto one.
Each of the StandardHttpContextMap is stills coped for the process group that all the components are in.
I'll admit I'm still a little shaky on controller services but it seem to work now.
I'm able to enable all the controller services form the root group with
.\conf\cli.properties
PS C:\Dev\aim\nifi-toolkit-1.9.1\bin> .\cli.bat nifi pg-enable-services -pgid 911b83b1-0169-1000-17bb-823bb530cf8c -p ..\conf\cli.properties
Thanks for the help it is much approceiated.

I'm having a problem with the command you showed below. When I run it for my stuff I get the following:
PS C:\Dev\aim\nifi-toolkit-1.9.1\bin> .\cli.bat nifi pg-enable-services -pgid aee943fb-48ac-351e-aef7-29db27d33b0f -p ..
\conf\cli.properties
ERROR: Error executing command 'pg-enable-services' : One or more services could not be enabled, run command with -verbose to obtain more details
The are for components referencing the StandardHttpContextMap, one HandleHttpRequest component and three HandleHttpResponse components.
Any suggestion on how to handle this error?

When a template, or a versioned flow, is instantiated, all the
processors are initially stopped and the services are disabled. This
is done on purpose since starting and enabling components may cause
interactions with external systems, and it may not be clear or desired
that just by instantiating the template that all of these interactions
are automatically going to take place. So it requires an extra step
where the user (or your script) must explicitly enabled and start the
components.
The NIFI CLI has a command "pg-enable-services" that can be used to
enable all the services in a given process group. You could call this
from your script like "./bin/cli.sh nifi pg-enable-service -pgid
someid".
