We are planning on using Jenkins (used to be Hudson) for the automated builds of our project.

I need to find out what it needs from a system requirements standpoint (RAM, disk, CPU) for a Linux RH installation.

We will be testing a Mobile application project.

I did check this post but couldn't find a response.

I've been maintaining a Jenkins / Sonar / Nexus and I pointed out a minimal configuration (Debian 5):

  • CPU : n/a (bye bye plain old school CPU at least ;) )
  • RAM : 1GB (I prefer 2)
  • HDD : depends on the needs. For my use, a 8 module J2EE Maven project + db scripts (6500 lines of code) represents less of 50 MB. I configured Jenkins to store 10 builds (500 MB)

However, if Jenkins has to manage several projects at the time, you have to consider few things:

  • keep Jenkins data in a separate directory of the system (default install may put those in /usr) with the Jenkins config way of your choice
  • mount a dedicated HDD partition on this directory and let you a way to manage space on disk (virtual drive, partition resizing tool...)
  • supervising activity to prevent space left and avoid an angry boss :) (Nagios for example)

Think about backup, other application on server, and a important thing - Jenkins resources depends on JVM capacity.
