# Kubernetes and LinuxKit
This project aims to demonstrate how one can create minimal and immutable Kubernetes OS images with LinuxKit.
Make sure to `cd projects/kubernetes` first.
Edit `kube-master.yml` and add your public SSH key to `files` section.
Build OS images:
```
make build-vm-images
```
Boot Kubernetes master OS image using `hyperkit` on macOS:
```
./boot-master.sh
```
Get IP address of the master:
```
ip addr show dev eth0
```
Login to the kubelet container:
```
./ssh_into_kubelet.sh <master-ip>
```
Manually initialise master with `kubeadm`:
```
kubeadm-init.sh
```
Once `kubeadm` exits, make sure to copy the `kubeadm join` arguments,
and try `kubectl get nodes` from within the master.
To boot a node use:
```
./boot-node.sh <n> [<join_args> ...]
```
More specifically, to start 3 nodes use 3 separate shells and run this:
```
shell1> ./boot-node.sh 1 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
shell2> ./boot-node.sh 2 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
shell3> ./boot-node.sh 3 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
```
