The total size of the images in the common and control-plane cache is 251M and 528M respectively. This changes drops the size of the cache images from 353M to 274M and from 630M to 530M, reducing the overhead from ~100M to ~20M. The initrd images shrink from 273M to 246M and from 416M to 363M (the initrd's are compressed). Signed-off-by: Ian Campbell <ijc@docker.com>
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.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.sh <n> [<join_args> ...]
More specifically, to start 3 nodes use 3 separate shells and run this:
shell1> ./boot.sh 1 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
shell2> ./boot.sh 2 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
shell3> ./boot.sh 3 --token bb38c6.117e66eabbbce07d 192.168.65.22:6443
