LAST DEPLOYED: Tue Oct  6 12:51:18 2020
NAMESPACE: jenkins-demo
STATUS: deployed
REVISION: 1
NOTES:
*******************
****DEPRECATED*****
*******************
* The Jenkins chart is deprecated. Future development has been moved to https://github.com/jenkinsci/helm-charts

1. Get your 'admin' user password by running:
  printf $(kubectl get secret --namespace jenkins-demo demo-jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo
2. Get the Jenkins URL to visit by running these commands in the same shell:
  export NODE_PORT=$(kubectl get --namespace jenkins-demo -o jsonpath="{.spec.ports[0].nodePort}" services demo-jenkins)
  export NODE_IP=$(kubectl get nodes --namespace jenkins-demo -o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT/login

3. Login with the password from step 1 and the username: admin

4. Use Jenkins Configuration as Code by specifying configScripts in your values.yaml file, see documentation: http:///configuration-as-code and examples: https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demos
