$jenkins::port does not properly manage listening port

[arioch]

Unless I'm mistaken $::jenkins::port does not properly manage the listening port on EL 7:

Consider the following snippet:

class { '::jenkins':
  port => '80',
}

When applying this adjustment the config file remains unchanged.

# grep -ri jenkins_port /etc/sysconfig/jenkins
JENKINS_PORT="8080"

Which obviously results in the module not being able to manage a number of settings:

@arioch The port parameter appears to not presently do anything. A refactor of both the port handling and the docs is needed but the former is tricky to do without breaking backwards compatibility.

TL;DR -- try this instead:

class{ 'jenkins':
  config_hash => { 'HTTP_PORT' => { 'value' => '9090' }},
}

Ps. - I doubt you'll be able to bind jenkins directly to a privileged port with the current init script. I suggest using iptables or a proxy server -- I use nginx in front jenkins.

@arioch I'm going to close this ticket since it is a duplicate of #214 but please let us know if the example I provided doesn't solve the problem.

@jhoblitt Your workaround doesn't work. It still persists HTTP_PORT=8080 in /etc/default/jenkins. If I manually change HTTP_PORT=9090 in default config, puppet will let it through like nothing:
