Description

This module installs, configures, and manages a Kubernetes cluster built from loose components.

The main focus is towards the current stable versions of K8s (1.18.x+), but it should be able to handle both older and newer versions without issues.

Usage

Set k8s::server::etcd_servers to a list of servers or k8s::puppetdb_discovery to true.

Setting up a server node (apiserver, controller-manager, scheduler):

class { 'k8s':
  role               => 'server',
  master             => 'https://kubernetes.example.com:6443',
# generate_ca        => true, # Only set true temporarily to avoid overwriting the old secrets
# puppetdb_discovery => true, # Will use PuppetDB PQL queries to manage etcd and nodes
}

Setting up a client node (kubelet, kube-proxy):

class { 'k8s':
  role   => 'node',
  master => 'https://kubernetes.example.com:6443',
}
