Setting up an image for the hudson.sapsailing.com server

This is an add-on to the regular EC2 image set-up described here. An Android SDK needs to be installed.

• Create a hudson user/group
• Make sure /home/hudson is a separate mount; probably just mount the existing volume of a previous installation
• Install an Android SDK under /home/hudson/android-sdk-linux; if you simply re-used an old /home/hudson mount this should already be in place.
• Install Eclipse to /home/hudson/eclipse to allow sharing it in case a large AWS instance is needed, e.g., for heap dump analysis.

• export /home/hudson/android-sdk-linux and /home/hudson/eclipse as follows in /etc/exports:

  /home/hudson/android-sdk-linux 172.31.0.0/16(rw,nohide,no_root_squash)
  /home/hudson/eclipse 172.31.0.0/16(rw,nohide,no_root_squash)

• Ensure you have EC2 / EBS snapshot backups for the volumes by tagging them as follows: WeeklySailingInfrastructureBackup=Yes for / and /home/hudson.

/home/hudson/repo has the Hudson build repository. The Hudson WAR file is under /usr/lib/hudson/hudson.war. /etc/init.d/hudson, linked to from /etc/rc0.d/K29hudson, /etc/rc1.d/K29hudson, /etc/rc2.d/K29hudson, /etc/rc3.d/S81hudson, /etc/rc4.d/K29hudson, /etc/rc5.d/S81hudson, and /etc/rc6.d/K29hudson, takes care of spinning up Hudson during instance re-boot. Hudson systemwide configuration is under /etc/sysconfig/hudson:
