Repository Details

Build verifiably conformant multi-node kubernetes clusters in containers.

My Own Kind

View a Transcript of the screenscast.

Features

  • Tracks the latest stable version

  • After downloading 'build' images a single node cluster builds in under 60 seconds

  • Very simple to use without need for YAML files

  • Builds kubernetes master and worker nodes in containers

  • Can create multi-master and multi-node clusters

  • Can create an haproxy load balancer to front master nodes with '--with-lb'

  • For multi-node clusters the 'create cluster' command returns when kubernetes is completely ready, with all nodes and pods up and ready.

  • Can skip master, worker, or load balancer set up

    • In this case the set-up scripts are placed in /root in the containers

    • The set-up scripts can be run by hand

    • Can do kubernetes the hard way (see kthwic)

  • Each release tested by AI and test logs saved in e2e-logs

  • Build and create can show extensive logs with '--tailf'

  • Supports docker, podman and moby

  • Written in Bash in the style of Go for maintainability - see Why Bash? and src/

Install on Linux, Mac or Windows

Note for Fedora Linux users: Cgroups 2 must be disabled. See Linux Installation Options.

Ensure Docker or Moby are installed first.

Add the following to your shell startup file, for example ~/.bashrc or ~/.zshrc:

alias mokbox='docker run --rm -ti --hostname mokbox --name mokbox -v /var/run/docker.sock:/var/run/docker.sock -v /var/tmp:/var/tmp myownkind/mokbox'

Close the terminal and start it again so the alias is created.

Then 'log in' to the work container:

mokbox

Use mokctl and kubectl, which are already installed in the 'mokbox' container:

mokctl build image --get-prebuilt-image

mokctl create cluster myk8s --masters 1

export KUBECONFIG=/var/tmp/admin-myk8s.conf

kubectl get pods -A

Type exit or Ctrl-d to 'log out' of mokbox. The mokbox container will be deleted but the kubernetes cluster will remain, as will the kubectl file,/var/tmp/admin-myk8s.conf.

To remove the kubernetes cluster:

mokbox

export KUBECONFIG=/var/tmp/admin-myk8s.conf

mokctl delete cluster myk8s

exit

Two docker images will remain, 'myownkind/mokbox' and 'myownkind/mok-centos-7-v1.19.1'. Remove them to reclaim disk space, or keep them around to be able to quickly build kubernetes clusters.
