Canonical’s support for Kubernetes 1.6.2 released

We’re proud to announce support for Kubernetes 1.6.2 in the Canonical Distribution of Kubernetes and the Kubernetes Charms. This is a pure upstream distribution of Kubernetes, built with operators in mind. It allows operators do deploy, manage, and operate Kubernetes on public clouds, on-premise (ie vSphere, OpenStack), bare metal, and developer laptops. Kubernetes 1.6.2 is a patch release comprised of mostly bugfixes.

Getting Started

Here’s the simplest way to get a Kubernetes 1.6.2 cluster up and running:

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

# macOS
 brew install conjure-up
 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.
