From fe49ee9006e9396c79f90365b9e814ee70c9fcee Mon Sep 17 00:00:00 2001 From: Petr Ospalý Date: Sat, 20 Apr 2019 00:53:01 +0200 Subject: Add support for RKE kubernetes implementation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added a new playbook rke.yml and role rke which uses rancher RKE: https://github.com/rancher/rke It's an implementation of the kubernetes from rancher.com folks and it is an alternative to the official kubernetes tool: kubeadm. NOTE: Rancher has a notion of a 'control plane' which cannot run with etcd on all nodes in a multi-node setup. Control-plane node is the first kubernetes node from the inventory (as of now).
