KubeCon + CloudNativeCon North America 2018

Trying to migrate Jenkins to Kubernetes broke our brains. We migrated our Jenkins-based build system from plain VMs + Chef to Kubernetes running on VMs in our SAP corporate datacenter. Here is how we did it so that you can too.

We will walk through some of the nitty-gritty details to build a Kubernetes cluster from scratch on virtual machines, walking through our open-source example repo:

Provisioning the Cluster:
* building a solid cluster with kubeadm
* preparation of the underlying OS
* how to keep the base machines clean
* system and application monitoring

Running Jenkins on Kubernetes safely:
* our helm charts + shell scripts
* sizing the pods for builds
* persistent volumes and backups

Additionally, we will discuss some of the lessons we discovered along the way:
* What problems got solved migrating Jenkins to K8s?
* Lessons for other legacy apps
