I have a bare-bones install of jenkins on my Ubuntu server that I installed using just sudo apt-get install jenkins, as a result, jenkins is now accessible from all the domains that point to my box by simply adding :8080 on the the URL.
I have successfully configured apache to proxy jenkins to I can access it from ci.mydomain.com, but I cannot work out how to prevent jenkins from being accessible on port 8080.
Here is my apache conf:
<VirtualHost xx.xx.xx.xx:80>
ServerAdmin [email protected]
ServerName ci.mydomain.com
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
ProxyRequests Off
<Proxy http://localhost:8080/*>
Order deny,allow
Allow from all
</Proxy>
</VirtualHost>
I've followed the Ubuntu instructions here, but they didn't seem to have any effect.

The default is port 8080. To disable (because you're using https), use port -1 . This option does not impact the root URL being generated within Jenkins logic (UI, inbound agent files, etc.). It is defined by the Jenkins URL specified in the global configuration.
Open the file using a text editor such as Notepad or Notepad++. Scroll down until you find the line that contains --httpPort=8080 and change the number to the port you want to set. Note: If you are using HTTPS with Jenkins, use java -jar jenkins. war --httpsPort=[port number] to change the port in the command prompt.
The default Jenkins installation runs on ports 8080 and 8443. Typically, HTTP/HTTPS servers run on ports 80 and 443, respectively.
You can use iptables since it's Ubuntu, to block all non-local access to port 8080.
iptables -A INPUT -p tcp --dport 8080 -s localhost -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
