Jenkins Helm Chart
Jenkins master and slave cluster utilizing the Jenkins Kubernetes plugin
Credit
This Chart was forked from https://github.com/kubernetes/charts/blob/master/stable/jenkins/ in order to provide the Cloud Posse flavor of CI/CD for Kubernetes. It’s based largely on the effort of Lachlan Evenson, Vic Iglesias to produce the original Chart, who were inspired by the awesome work of Carlos Sanchez carlos@apache.org.
