how to setup nifi.content.repository.archive.max.retention.period in a Nifi docker image ?

[Nicolas Belot]

Hello everyone.

I use a docker image of nifi and I need to tune 
nifi.content.repository.archive.max.retention.period.

Is there a way to simply  set it up through an env variable ?

I read the start.sh script but 
nifi.content.repository.archive.max.retention.period  does not appear in this 
script.

Regards

N.
