# 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`

|
|
- [jq](https://stedolan.github.io/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:
|
|
```sh
|
|
./scripts/copy_file_to_nodes cluster.config
|
|
```
|
|
|
|
- install the jq CLI on the nodes so they can read the config
|
|
```sh
|
|
./scripts/run_script_on_nodes install_jq_cli
|
|
```
|
|
|
|
- setup a container runtime
|
|
```sh
|
|
./scripts/run_script_on_nodes install_container_runtime
|
|
```
|
|
|
|
- download kubernetes
|
|
```sh
|
|
./scripts/download_kubernetes_binaries $(cat cluster.config | jq -r ".kubernetes_version") ./kubernetes
|
|
```
|
|
- download etcd
|
|
```sh
|
|
./scripts/download_etcd_binaries $(cat cluster.config | jq -r ".etcd3_version") ./etcd3
|
|
```
|
|
|
|
- copy kubelet & kube-proxy on the worker nodes
|
|
```sh
|
|
./scripts/copy_file_to_nodes ./kubernetes/workers worker
|
|
```
|
|
|
|
- copy etcd, kubelet, kube-proxy, apiserver, scheduler and native controllers binaries to the master nodes
|
|
```sh
|
|
./scripts/copy_file_to_nodes ./etcd3 master
|
|
./scripts/copy_file_to_nodes ./kubernetes/masters master
|
|
``` |
