Canonical Distribution of Kubernetes - Release 1.5.3

We’re proud to announce support for Kubernetes 1.5.3 in the Canonical Distribution of Kubernetes. This is a pure upstream distribution of Kubernetes, designed to be easily deployable to public clouds, on-premise (ie vsphere, openstack), bare metal, and developer laptops. Kubernetes 1.5.2 is a patch release comprised of mostly bugfixes, and we encourage you to check out the release notes.

Getting Started:

Here’s the simplest way to get a Kubernetes 1.5.3 cluster up and running on an Ubuntu 16.04 system:

sudo snap install conjure-up --classic
conjure-up kubernetes

During the installation conjure-up will ask you what cloud you want to deploy on and prompt you for the proper credentials. If you’re deploying to local containers (LXD) see these instructions for localhost-specific considerations.

For production grade deployments and cluster lifecycle management it is recommended to read the full Canonical Distribution of Kubernetes documentation.

How to upgrade

With your kubernetes model selected, you can deploy the bundle to upgrade your cluster if on the 1.5.x series of kubernetes. At this time releases before 1.5.x have not been tested. Depending on which bundle you have previously deployed, run:

    juju deploy canonical-kubernetes


    juju deploy kubernetes-core

If you have made tweaks to your deployment bundle, such as deploying additional worker nodes as a different label, you will need to manually upgrade the components. The following command list assumes you have made no tweaks, but can be modified to work for your deployment.

juju upgrade-charm kubernetes-master
juju upgrade-charm kubernetes-worker
juju upgrade-charm etcd
juju upgrade-charm flannel
juju upgrade-charm easyrsa
juju upgrade-charm kubeapi-load-balancer

This will upgrade the charm code, and the resources to kubernetes 1.5.3 release of the Canonical Distribution of Kubernetes.
