Rancher 2.2 has reached GA and is available for immediate use. It's packed with features for Day 2 Kubernetes operations, designed to make clusters and their workloads more available and easier to manage. This article describes the main features in 2.2, their benefits, and when to use them.
In this article we talk about Etcd, what it is, how it works, and how Kubernetes is using it internally. We then walk through how to use Rancher to deploy an Etcd cluster within Kubernetes. By following the steps in this article, you will have a fully functional installation of Etcd. Once Etcd is up and running, we will go over some basic Etcd commands and demonstrate Etcd's cluster availability under failure conditions.
