# 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 `runc exec kubelet kubectl get nodes`.
|
|
|
|
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
|
|
```
