This gist describes how to do a one-time initialization routine across several nodes particpating in a distributed cluster.

File	Description
`kube-init.sh`	The script that performs the init routine. The etcd calls inside of the script ensure the init routine is executed exactly once, even if the script is executed on multiple nodes in the cluster.
`kube-init.service`	The SystemD service unit that executes the script once across multiple boots
`kube-online.target`	A SystemD target for synchronizing on when K8s is ready

Why?

Because some people prefer ./configure over containers.

Omitted Modules

Please note the following modules were omitted on purpose due to Container Linux lacking the required libraries:
