In March we created some [Juju](https://jujucharms.com/u/kubernetes/kubernetes-master/trusty) [charms](https://jujucharms.com/u/kubernetes/kubernetes/trusty) that have the ability to deploy specific releases of [Kubernetes on a public cloud](https://github.com/GoogleCloudPlatform/kubernetes/tree/master/cluster/juju). In April we worked to get the charm and bundle code in the Kubernetes project itself. Making it even easier for people to deploy a cluster from the [official Kubernetes repository](https://github.com/GoogleCloudPlatform/kubernetes). We have reached another milestone in the Kubernetes story. We added the ability to deploy a Kubernetes cluster with binaries built from local source! This is important to software engineers because it gives them an easy way to stand up a cluster and see their changes right away. ## Development setup To use this new feature the local environment must be set up for development. Refer to the [Development Guide](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/devel/development.md) for details on how to set up your environment for development in the [Go](http://golang.org/) programming language. ## Deploy local binaries We are calling this deploy from source option “local”. Here is how it works: * Clone the Kubernetes project from Github: ``` git clone http://github.com/GoogleCloudPlatform/kubernetes.git cd kubernetes ``` * Set the Kubernetes provider to “juju”: ``` export KUBERNETES_PROVIDER=juju ``` * Change/edit the source code, and when you are ready, run the kube-up.sh script to deploy a cluster with your locally built binaries: ``` cluster/kube-up.sh ``` The kube-up.sh script will build the required binary files (using make all), copy the binary files to the charm directory and deploy a cluster to the [public cloud you have configured with Juju](https://jujucharms.com/docs/devel/getting-started#configuring), if you do not have a public cloud configured you will be presented with the opportunity to configure one. The resulting cluster consists of one kubernetes-master, two kubernetes nodes on different hosts. The [etcd](https://coreos.com/etcd/) and [flannel](https://github.com/coreos/flannel) parts are there so the containers on different hosts can communicate with each other. To get access to the controller node use juju ssh kubernetes-master/0 or the minion nodes with juju ssh kubernetes/0 commands. You will find the kubectl is already installed on the controller node. When you are done with the cluster running kube-down.sh will destroy the cluster as expected. ``` cluster/kube-down.sh ``` ## Why use Kubernetes with Juju? Juju provides a way to model deployments in a cloud agnostic language. The same commands can deploy a cluster on the major public clouds [Amazon](https://jujucharms.com/docs/devel/config-aws), [Google Compute Engine](https://jujucharms.com/docs/devel/config-gce), [any OpenStack cloud](https://jujucharms.com/docs/devel/config-openstack), [Windows Azure](https://jujucharms.com/docs/devel/config-azure) and [many others](https://jujucharms.com/docs/devel/getting-started). You will need to put your cloud credentials into Juju but that only needs to be done one time. This allows you to deploy a cluster on AWS, juju switch gce and deploy the same cluster on the GCE public cloud using the same kube-up.sh command. Juju reduces the cost of experimentation on other clouds and lets you focus on the Kubernetes development. ## Help us improve! There is a small team working on the Kubernetes story [@whitmo](https://github.com/whitmo), [@chuckbutler](https://github.com/chuckbutler), and [@mbruzek](https://github.com/mbruzek). We are always trying to improve and make something useful for the community. If you find a bug in the code create an [issue](https://github.com/googlecloudplatform/kubernetes/issues) and reference one or all of us in the issue and we will have a look. If you have any feedback or a use case that we can help with please let us know. You can reach us on IRC in #system-zoo on irc.freenode.net.
