---------------------------------------
Summary: Enable NiFi Docker image to bind on low ports
Key: NIFI-8275
URL: https://issues.apache.org/jira/browse/NIFI-8275
Project: Apache NiFi
Issue Type: Improvement
Components: Docker
Affects Versions: 1.12.1, 1.13.0
Environment: Any docker environment
Reporter: Jose Luis Pedrosa
Currently Docker image creates and asignes an user `nifi` with guid 1000. This
user is not allowed to listen in low ports (<1024), this means that it is not
possible to have NiFi web running on port 80.
In order to enable this, the Java process needs to have the NET_BIND_SERVICE
capability assigned. This by it's own won't allow to listen on low ports, but
if the user assigns that capability to the container (docker or kubernetes),
then it is possible.
