The Google Cloud Platform released version 1.0 of the Kubernetes project. The name “kubernetes” originates from Greek, meaning “helmsman” or “pilot”. Kubernetes is an open source software system for managing containerized applications across multiple hosts. It handles the scheduling the nodes, and reorganizes the cluster when workloads or nodes fail (called “self-healing”).
Kubernetes introduces some new technology specific concepts such as “cluster”, “node”, “pod”, “replication controller”, and “service”. If you need more information check out the concepts on github. We also wrote a getting started guide for using Juju.
Canonical have been working on Kubernetes for about 6 months. The bundle and charms are in the cluster/juju directory of the kubernetes github project. We have created the best way to deploy a cluster with Juju so you can get started using the technology without having to know how to deploy the cluster on a specific cloud. The important part of this integration is that you can deploy a cluster in all the clouds that Juju supports (which is pretty much all of the public clouds)!
Assuming you already have Juju installed (because who doesn't ... am I right?) you can deploy a Kubernetes cluster in two different ways:
We engineered the charms to deploy a specific tagged release of the kuberentes project. At the time of writing this is "v1.0.0" but the version can change. Use quickstart to deploy the bundle from the Juju charm store:
juju quickstart u/kubernetes/kubernetes-cluster
If you want to develop Kubernetes features or fix bugs you can deploy the developer version and see your changes in the cluster right away! Since the charms and bundles are integrated in the repository you can use Kubernetes semantics to deploy the cluster (a.k.a. kube-up.sh).
git clone https://github.com/GoogleCloudPlatform/kubernetes.git
I wrote more about the developer cluster in a previous post.
My colleague created a video that visualizes the features we have added. Check out his video on YouTube.
I wrote more about the Kubernetes 1.0 release on Ubuntu Insights.
Congratulations to Google for reaching the significant milestone v1.0!
