Kubernetes on Novena

Some steps I've taken to install Kubernetes on Debian.

1. Update the key.

 wget http://repo.novena.io/debian/pool/main/k/kosagi-repo/kosagi-repo_1.2-r1_all.deb
 sudo dpkg -i kosagi-repo_1.2-r1_all.deb
 apt-get update
 DEBIAN_FRONTEND=noninteractive apt-get dist-upgrade

2. At this point, it's probably a good idea to move to a SATA disk.

 dd if=/dev/mmcblk0 of=/dev/sda bs=1M count=1
 fdisk /dev/sda
 # Re-create partitions 2 and 3.  Make partition 2 at least 6GB
 # for swap (type 82), and make partition 3 the rest of the disk.
 # Type "x" for Expert mode, then "i", and change the ID to 0x4e6f7653.
 # Then "r" to return to the main menu, and "w" to write it to disk.
 mkfs.ext4 /dev/sda3 # or install btrfs-tools or xfsprogs and make a different type
 mount /dev/sda3 /mnt
 rsync -avxHAX --progress / /mnt/
 novena-eeprom -w -f es8328,pcie,gbit,hdmi,eepromoops,sataroot

3. Install Docker (borrowed from https://github.com/hypriot/image-builder-odroid-c1/blob/master/builder/chroot-script.sh)

 wget -q https://packagecloud.io/gpg.key -O - | apt-key add -
 echo 'deb https://packagecloud.io/Hypriot/Schatzkiste/debian/ jessie main' > /etc/apt/sources.list.d/hypriot.list
 apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2C52609D
 echo 'deb [arch=armhf] https://apt.dockerproject.org/repo debian-jessie main' > /etc/apt/sources.list.d/docker.list
 apt-get update
 export DOCKER_ENGINE_VERSION="17.03.0~ce-0~debian-jessie"
 export DOCKER_COMPOSE_VERSION="1.9.0-23"
 export DOCKER_MACHINE_VERSION="0.9.0-39"
 DEBIAN_FRONTEND=noninteractive apt-get install \
   libltdl7 \
   docker-engine="${DOCKER_ENGINE_VERSION}" \
   docker-compose="${DOCKER_COMPOSE_VERSION}" \
   docker-machine="${DOCKER_MACHINE_VERSION}"

4. Install kubeadm

 curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
 echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" > /etc/apt/sources.list.d/kubernetes.list
 apt-get update && apt-get install -y kubeadm

5. Run kubeadm to start the cluster. As of this moment, we need to skip preflight checks due to changes in Docker version numbering.

 kubeadm init --pod-network-cidr 10.244.0.0/16 --skip-preflight-checks
