  hackweek19 openSUSE MicroOS/Kubic JUST Get Started

  Q: what the difference between MicroOS and Kubic?
  First impression from openSUSE Wiki is confusing: they are Tumbleweed variants

  Kubic DVD installation: kubic-template, kubic-master, kubic-worker1

  1. VM: kubic-template

  Kubic DVD -> System Role = kubeadm

  transactional-update pkg install yast2-network

  ( NOTE: not allowed, zypper in yast2-network )

  1. Copy VM to: kubic-master, kubic-worker1

  To manipulate overlayfs(/etc) on top of readonly rootfs

  virt-dup -o kubic-template -n kubic-master,ip=192.168.200.100/24
  virt-dup -o kubic-template -n kubic-worker1,ip=192.168.200.101/24

  https://github.com/zzhou1/virt-dup

  1. kubic-master bootstrap

     kubeadm --v=5 init 
  
     [preflight] pref-light-check
     . [ERROR NumCPU]: the number of available CPUs 1 is less than the required 2
     . [ERROR FileContent--proc-sys-net-ipv4-ip_forward]
       https://github.com/kubernetes/kubeadm/issues/1062
       bsc#1163328 Kubic Installer System Role should not disable ip_forward
     . [ERROR ImagePull]: ... net/http: TLS handshake timeout
       NOTE: Need pull ~500M image from the bad internet connection.  
             Have to give up from home, so far!
  

  Install Kubic with cloud-init and VM images

  1. "cloud-init ready" VM images https://download.opensuse.org/repositories/devel:/kubic:/images/

  2. prepare cloud-init CD-ROM: ci-data.iso

     PWD=$(pwd)
     mkdir -p $PWD/kubic/cloud-init-iso
  
     cd $PWD/kubic/cloud-init-iso
     touch meta-data user-data
     REF: https://en.opensuse.org/Kubic:MicroOS/cloud-init
  
     eg.
     meta-data:  instance-id: xxxxx
     user-data:  add your own ssh-key for passwordless access
     user-data:  add your user/passwd
     user-data:  root-passwd=linux
  
     cd $PWD/kubic/
     sudo mkisofs -output ci-data.iso -volid cidata -joliet -rock cloud-init-iso
  

  1. boot VM img with CD-ROM ci-data.iso
     

  Enjoy passwordless ssh!

  Takeaway

  • Two installation approaches:

    • DVD
    • cloud-init VM image is a very handy

  • BAD: so far, the internet requirement is to high to do kubeadm init yet to figure out the workaround for China

  One more progress to make my Friday. I can move one more step with --image-repository registry.cn-hangzhou.aliyuncs.com/google_containers.
