Assignee: (was: Aakash Chauhan)
> Replace properties in nifi.properties by environment variables

> Project: Apache NiFi

> Components: Configuration, Docker

> {{start.sh}} replaces some properties defined in {{nifi.properties}} with a
> set of environment variables.
> This adds some flexibility as the users are able to modify properties without
> touching the {{nifi.properties}} file but it can lead to some frustration
> when users think they can replace any property by defining an environment
> variable with the same name. Also, when users want to provide their own
> {{nifi.properties}} file as some properties will be overwritten.
> I believe we should only replace a property when there is an environment
> variable defined with the same name (we should use the same names that appear
> in the {{nifi.properties}} file in uppercase and replacing any {{.}} with
> {{_}}). Defaults should be taken from the {{nifi.properties}} file.
> This way users can replace the properties file with a custom one, choose to
> define environment variables, or both.
