+Building my own Jenkins Image including as set of preinstalled plugins
+===
+
+This is mainly built for configuring Jenkins with code but also is built to learn and understand how to build container images in a k8s cluster without docker installed.
+
+We will use "kaniko".
+
+Prerequisites:
+- a private docker registry, in this setup I use my own harbor instance
+- namespace in the k8s cluster where this all will run e.g. "build"
+- a secret for kaniko to log into the registry
+
+The secret:
+
+```
+kubectl create secret docker-registry registry-credentials --docker-username='robot$jenkins' --docker-password=XXXXXXXXXXXXXXXXXXXXXX --docker-email=matthias.hinrichs@me.com  --docker-server='https://harbor.hnrx.net
+```
