How to consume Jenkins API Rest in Google Kubernetes Engine from external clients

Question

I want to try out continuous deployment with Jenkins on Google Kubernetes Engine. Of course, by using the Jenkins API Rest.

I have gone through https://cloud.google.com/solutions/jenkins-on-container-engine-tutorial

I got Jenkins running. The problem is with regard to the Jenkins API Rest when I try to consume it by using Postman or curl. I'm prompted to Sign in to continue to Google Cloud Shell.

By using curl

curl -X GET https://8080-dot-3828316-dot-devshell.appspot.com/job/dev.ci/api/json\?pretty\=true --user USER:TOKEN

Answer 1

My problem was related to the fact that I didn't expose the service properly. I was using the preview URL that Google provides you. So I had to follow the architecture shown here: https://cloud.google.com/solutions/jenkins-on-kubernetes-engine?fbclid=IwAR19Dl_kUSGzK1cfqyYA1s9cNt26CBnSgXf6zV104NGtIiXNtpTTKrfo3TI. I had to expose my jenkins ui as a NodePort and learn about ingress.
