Introduction

This repository is intended for demo-ing the manual install of kubernetes's components on both master and worker nodes.

It should be able to get you to a working single master (insecure) kubernetes setup on a set of VMs

prerequisites

vagrant
the scp vagrant plugin : vagrant plugin install vagrant-scp
the GNU parallel CLI
jq

setup

run vagrant up to start the vms. This will create a master node and 2 worker nodes on your host's network
run ./scripts/show_cluster_config | tee cluster.config
copy the cluster configuration to the nodes:

./scripts/copy_file_to_nodes cluster.config

install the jq CLI on the nodes so they can read the config

./scripts/run_script_on_nodes install_jq_cli

setup a container runtime

./scripts/run_script_on_nodes install_container_runtime

download kubernetes

./scripts/download_kubernetes_binaries $(cat cluster.config | jq -r ".kubernetes_version") ./kubernetes

download etcd

./scripts/download_etcd_binaries $(cat cluster.config | jq -r ".etcd3_version") ./etcd3

copy kubelet & kube-proxy on the worker nodes

./scripts/copy_file_to_nodes ./kubernetes/workers worker

copy etcd, kubelet, kube-proxy, apiserver, scheduler and native controllers binaries to the master nodes

./scripts/copy_file_to_nodes ./etcd3 master
./scripts/copy_file_to_nodes ./kubernetes/masters master
