We are proud to release the latest Charms supporting Kubernetes version 1.6.1!
Kubernetes 1.6 is a major milestone for the community, we’ve got a full write up of features and support on our blog < https://insights.ubuntu.com/2017/04/12/general-availability-of-kubernetes-1-6-on-ubuntu/ > Getting Started Here’s the simplest way to get a Kubernetes 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 < https://kubernetes.io/docs/getting-started-guides/ubuntu/local/> for localhost-specific considerations. For production grade deployments and cluster lifecycle management it is recommended to read the full Canonical Distribution of Kubernetes documentation <https://kubernetes.io/docs/getting-started-guides/ubuntu/>. Upgrading an existing cluster If you’ve got a cluster already deployed, we’ve got instructions to help get you upgraded. If possible, deploying a new cluster will be the easiest route. Otherwise, the instructions for upgrading are outlined here: https://insights.ubuntu.com/2017/04/12/general-availability-of-kubernetes-1-6-on-ubuntu/#upgrades Changes in this release - Support for Kubernetes v1.6, with the current release being 1.6.1 - Installation of components via snaps: kubectl, kube-apiserver, kube-controller-manager, kube-scheduler, kubelet, and kube-proxy. To learn more about snaps: https://snapcraft.io - Added ‘allow-privileged’ config option on kubernetes-master and kubernetes-worker charms. Valid values are true|false|auto (default: auto). If the value is ‘auto’, containers will run in unprivileged mode unless GPU hardware is detected on a worker node. If there are GPUs, or the value is true, Kubernetes will set `--allow-privileged=true`. Otherwise the flag is set to false. - Added GPU support (beta). If Nvidia GPU hardware is detected on a worker node, Nvidia drivers and CUDA packages will be installed, and kubelet will be restarted with the flags required to use the GPU hardware. The ‘allow-privileged’ config option must be ‘true’ or ‘auto’. - Nvidia driver version = 375.26; CUDA version = 8.0.61; these will be configurable future charm releases. - GPU support does not currently work on lxd. - This feature is beta - feedback on the implementation is welcomed. - Added support for running your own private registry, see the docs here <https://github.com/juju-solutions/kubernetes/tree/1.6-staging/cluster/juju/layers/kubernetes-worker#private-registry> for instructions. General Fixes: - Fixed a bug in the kubeapi-load-balancer not properly forwarding SPDY/HTTP2 traffic for `kubectl exec` commands. Etcd specific changes: - Installation of etcd and etcdctl is now done using the `snap install` command. - We support upgrading the previous etcd charm, to the latest charm with snap delivery mechanism. See manual upgrade process for updating existing etcd clusters. Changes to the bundles and layers: - Add registry action to the kubernetes-worker layer, which deploys a Docker registry in Kubernetes. - Add support for kube-proxy cluster-cidr option. Test results The Canonical Distribution of Kubernetes is running daily tests to verify it works with the upstream code. As part of the Kubernetes test infrastructructure we upload daily test runs. The test results are available on the dashboard. Follow along with our progress here: https://k8s-gubernator.appspot.com/builds/canonical-kubernetes-tests/logs/kubernetes-gce-e2e-node/ How to contact us We're normally found in the Kubernetes Slack channels and attend these Special Interest Group (SIG) meetings regularly: - sig-cluster-lifecycle < https://kubernetes.slack.com/messages/sig-cluster-lifecycle/> - sig-cluster-ops <https://kubernetes.slack.com/messages/sig-cluster-ops/ > - sig-onprem <https://kubernetes.slack.com/messages/sig-onprem/ <https://kubernetes.slack.com/messages/sig-cluster-ops/>> Operators are an important part of Kubernetes, we encourage you to participate with other members of the Kubernetes community!
