Hostname resolution errors on CruiseControl.rb on Ubuntu 9.04
I finally resolved an error I’ve been having with CruiseControl.rb with our Ruby on Rails project in Subversion (SVN). Currently we use RoR with Cucumber for our BDD and CruiseControl.rb as the CI environment. Below are the steps I’ve taken and the final resolution to fix the problem:
1. Setup Ubuntu Server 9.04 (grab all the necessary gems, subversion, db, etc.)
2. After downloading the source from http://cruisecontrolrb.thoughtworks.com/
3. cd ~/cruisecontrol-1.4.0
4. ./cruise add ProjectName –repository ‘https://projectpath.com/trunk‘ -s subversion –username cruisecontrol –password secretpassword
At this point, the code properly checked out of subversion and I didn’t receive any errors.
5. cd ~/.cruise/projects/ProjectName/
6. edit cruise _config.rb and uncomment project.rake_task = ‘features’
This will build using the ‘cucumber features’ tests
7. cd ~/cruisecontrol-1.4.0 and run ./cruise start
At this point the CruiseControl.rb server is supposed to startup, svn update your projects, and run a build if necessary. I notice that I received errors:
svn –non-interactive log –limit 1 –revision HEAD:1 –verbose –xml
Host not found
I went into the ~/.cruise/projects/ProjectName/work/ directory and ran a svn update and it would intermittently work and other times return “host not found”.
8. Since this appeared to be a DNS issue I modified the DNS entries via:
sudo vi /etc/resolv.conf
modified and added a line for 4.2.2.2 (Verizon’s public DNS server).
9. I reran step 7 and magically my CruiseControl.rb build ran successfully
