Here’s a look at what we did. ### Fixes and Improvements Check out the [full list](https://github.com/juju-solutions/bundle-canonical-kubernetes/milestone/10?closed=1) on GitHub. Here are some notables: * Made load balancer port configurable * Changed default `--service-cluster-ip-range` to a `/16` CIDR to allow more NodePort IP addresses * Fixed etcd snapshot action * Increased default worker node constraints to 4 cpu, 4GB RAM ### Testing * Added a test to ensure dashboard is operational after deploy * Added a test for the built-in microbot example * Added a Jenkins job to test master charms with stable snaps. When this is green it means we can release whatever new fixes/features we have queued up in the charms, giving us the confidence to do **more frequent releases.** ### Features * [Calico](https://www.projectcalico.org/) spike. We want to provide a CDK + Calico deployment option that works on any cloud, just like our CDK + Flannel option. We’ve decided to go with a Calico-on-Flannel ([Canal](https://github.com/projectcalico/canal)) approach initially. Canal combines the network policy enforcement of Calico with the ease-of-deployment of Flannel. Work begins in the current sprint! * [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/) spike. We mapped out the work necessary for enabling RBAC via charm config. Work begins in the current sprint! * Updated the [canonical-kubernetes-elastic](https://jujucharms.com/canonical-kubernetes-elastic/) bundle. This bundle has been added to our Jenkins build process and updated with the latest 1.7 charms. --- If you’d like to follow along more closely with CDK development, you can do so in the following places: *  (cluster/juju directory) * * Kubernetes [Slack channels](http://slack.k8s.io/) and [SIG meetings](https://kubernetes.io/community/) * #juju on Freenode IRC * [juju@lists.ubuntu.com](mailto:juju@lists.ubuntu.com) mailing list Until next time!
