Foward Jenkins to your localhost on port 8080

kubectl --namespace default port-forward svc/jenkins 8080:8080

Now you can access your jenkins on http://localhost:8080
User: admin
Pass: admin

A Jenkins Job with name "simple-app" is set in home page and configured with the shared libraries call, but before executing it, you MUST access menu option "Manage Jenkins">"In-process Script Approval" and approve the pipeline script, or access through url http://localhost:8080/scriptApproval/ and approve the pipeline script.

All set up, now just run the "Simple-App" job and enjoy 🤩

After pipeline execution you can access de deployed application

Foward our simple application
