conjure-up Canonical Kubernetes under LXD today!

We've just added the Localhost (LXD) cloud type to the list of supported cloud type on which you can deploy The Canonical Distribution of Kubernetes.

What does this mean? Just like with our OpenStack offering you can now have Kubernetes deployed and running all on a single machine. All moving parts are confined inside their own LXD containers and managed by Juju.

It can be surprisingly time-consuming to get Kubernetes from zero to fully deployed. However, with conjure-up and the driving technology underneath, you can get straight Kubernetes on a single system with LXD, or a public cloud such as AWS, GCE, or Azure all in about 20 minutes.

Getting Started

On Xenial and above simply run:

$ sudo snap install conjure-up --classic

Note: Trusty users will need to run a few additional commands:

$ sudo apt-get install snapd
$ sudo groupadd lxd && sudo usermod -a -G lxd $USER
$ sudo reboot
$ sudo snap install conjure-up --classic --beta

Now deploy Kubernetes.

$ conjure-up kubernetes

Walkthrough

We all like pictures so the next bit will be a screenshot tour of deploying Kubernetes with conjure-up.

For this walkthrough we are going to create a new controller, select the localhost Cloud type:

Deploy the applications:

Wait for Juju bootstrap to finish:

Wait for our Applications to be fully deployed:

Run the final post processing steps to automatically configure your Kubernetes environment:

Review the final summary screen:

Accessing your Kubernetes

You can access your Kubernetes by running the following:

$ ~/kubectl --kubeconfig=~/.kube/config

Or if you've already run this once it'll create a new config file as shown in the summary screen.

$ ~/kubectl --kubeconfig=~/.kube/config.conjure-up

Deploy a Workload

As an example for users unfamiliar with Kubernetes, we packaged an action to both deploy an example and clean itself up.

To deploy 5 replicas of the microbot web application inside the Kubernetes cluster run the following command:

$ juju run-action kubernetes-worker/0 microbot replicas=5

This action performs the following steps:

It creates a deployment titled 'microbots' comprised of 5 replicas defined during the run of the action. It also creates a service named 'microbots' which binds an 'endpoint', using all 5 of the 'microbots' pods.

Finally, it will create an ingress resource, which points at a xip.io domain to simulate a proper DNS service.

To see the result of this action run:

Mother will be so proud.
