Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

	#!/bin/bash

	# ------------------------------------------------------------------------------
	# xfce-app-switcher.sh
	#
	# A script that lets you pin both launching and switching to an application
	# using the same hotkey, similar to what you get by default in other
	# environments like i3 or Cinnamon.
	#
	# To use: Open XFCE Keyboard settings and create a shortcut that runs this

	This demonstrates how to make client side certificates with go

	First generate the certificates with

	./makecert.sh [email protected]

	Run the server in one terminal

	go run server.go

	/*

	Go-Language implementation of an SSH Reverse Tunnel, the equivalent of below SSH command:

	ssh -R 8080:127.0.0.1:8080 operatore@146.148.22.123

	which opens a tunnel between the two endpoints and permit to exchange information on this direction:

	server:8080 -----> client:8080

	# TODO: replace :token, :user, and :repo
	curl -H "Authorization: token :token" \
	-H 'Accept: application/vnd.github.everest-preview+json' \
	"https://api.github.com/repos/:user/:repo/dispatches" \
	-d '{"event_type": "awesomeness", "client_payload": {"foo": "bar"}}'
