| I copy pasted exact code from above git repo and tried running it,.. Jos is waiting for slave to be up and running to run the job but slave never came up and here what I find in the kubernetes:

[root@<kubernetes-master> kubernetes]#
secret volume was the only difference what I had in my earlier try volumes: [secretVolume(secretName: 'shared-secrets', mountPath: '/etc/shared-secrets')]. The steps I'm trying are : 1. export API_HOST_IP="0.0.0.0"
2. Running the kubernetes cluster with the help of "./hack/local-up-cluster.sh"
3. exposed 8080 port on the same machine
4. Configured the kubernetes cloud in the jenkins configuration with IP : http://<kubernetes-master>:8080
5. Created this job and running it. Please let me know if I'm missing something here? like creating some sort of a secret and put it somewhere! |
