The minimum to run a NiFi instance is as follows:
docker run --name nifi \
- -p 18080:8080 \
+ -p 8080:8080 \
-d \
apache/nifi:latest

Enjoy the English touch with "recognised" instead of "recognized" =)

> Key: NIFI-4824
> URL: https://issues.apache.org/jira/browse/NIFI-4824
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Docker
> Affects Versions: 1.2.0, 2.0.0, 1.3.0, 1.4.0, 1.5.0, 1.6.0
> Reporter: Daniel Chaffelson
> Priority: Critical
>
> As a user of the official apache/nifi Docker image, I would like to be able
> to easily pass in the ports I want NiFi to start on. This is particularly
> important since the 1.5.0 release, where remapping ports outside the
> container cause NiFi to throw a security error.
> This will be particularly useful in NiFI-1.5.0 and newer, where users are
> often running multiple instances of the same version in order to test Flow
> Versioning and other new features around the NiFi-Registry project.
> This can be done by slightly modifying the startup scripts included in the
> package to use an environment variable if available, or a default if it is
> not provided. It is then very easy to pass an environment variable to the
> Docker image on startup.
