How to boot automatically ?

Is there any simple way to boot it automatically at linux ?

Not quite sure what you are asking, but if you are asking whether it is possible to automatically boot a linuxkit/kubernetes VM at host boot then that would be something to arrange via your VM management software whatever that is. On that subject it is worth mentioning that boot.sh and friends are really for development and demo purposes, for production (or production like) scenarios you should use proper a VM management stack.
