Delete the relevant section from the .gitmodules file.
Stage the .gitmodules changes git add .gitmodules
Delete the relevant section from .git/config.
Run git rm --cached path_to_submodule (no trailing slash).
Run rm -rf .git/modules/path_to_submodule (no trailing slash).
Commit git commit -m "Removed submodule "
Delete the now untracked submodule files rm -rf path_to_submodule

Persistent data storage on CoreOS-cluster

Storing the data on the host machine

Data directories are created in /home/coreos and mounted into the container using volume cli options of docker run. All data the container writes is stored on the host and as long as the host persists safe against container restarts / recreates.

Pro
- No effort, just create the directories and mount them into the container
Contra
Container is bound to host (unable to failover)

This document outlines steps and common tasks for setting up a arm64 dev machine for LinuxKit.

Notes on packet.net

If you set up a server on packet.net using the docker account please use your name/slackhandle/initials in the machine name. We will garbage collect machine and whack machine not adhering to this policy without warning :).

Deploy a Ubuntu 16.04 LTS server on packet.net and ssh in as root.
