| Hello - I have my own Openshift 1.3 Origin Cluster and im launching Jenkins via s2i template.
Jenkins docker image was built close to openshift:jenkinsci (Ben Parees: https://github.com/openshift/jenkins) with few customizations plus Ubuntu OS instead of Centos. When Jenkins is launched, it is filled with Kubernetes errors with unknown host. Although I dont think its a Jenkin bug, im looking for assistance. oc describe pod jenkins-openshift5-6-msta8
