iPXE with Netboot.xyz

Leverage Docker and Netboot.xyz to host Harvester/Rocky/Liberty installers and kickstart. We have been developing an Harvester Workshop and needed a better way to boot dozens of machines. Netboot.xyz was a simple way to do it. We used https://hub.docker.com/r/linuxserver/netbootxyz to simplify the install.

Then we created a custom menu and loaded the assets. After updating the DHCP settings on the network to point to the machine we are able to boot anything.

systemd Service Unit for Traefik

Adapted from the forked gist and this blog. Adjusted to our own implementation.

The provided file should work with systemd version 219 or later. It might work with earlier versions. The easiest way to check your systemd version is to run systemctl --version.

Instructions

Installing KVM, libvirt, Docker-CE and Kubernetes on Centos 7.x

First of all be root while doing this... sudo su

Set hostname

Set the hostname:

hostnamectl set-hostname 'k8s-master'

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Install first for ubuntu:

sudo apt-get install build-essential libssl-dev curl git-core

Compile the required Node.js version and put in global reach:

# install Node.js from Github (replace 4.0.0 with required version)
git clone https://github.com/nodejs/node.git node4.0.0

Install first for ubuntu:

sudo apt-get install build-essential libssl-dev curl git-core

Compile the required iojs version and put in global reach:

# install iojs from Github (replace 1.3.0 with required version)
git clone https://github.com/iojs/io.js.git iojs

process._debugProcess(process.pid)

process._debugPause()

process._debugEnd()

process.debugPort : is getter and setter of debugport

Init Script

From: source

Init scripts hopefully need no explanation. Scripts reside in /etc/init.d with root ownership and executable permissions. e.g.:

sudo su
cp my-application-script /etc/init.d/my-application

	#
	# This needs to be installed here:
	# /etc/systemd/system/consul.service
	#

	[Unit]
	Description=consul
	Requires=network-online.target
	After=network-online.target

	#!/bin/bash
	#
	# chkconfig: - 55 45
	# init.d example for Forever & Node
	#
	# modeled after
	# https://gist.github.com/jinze/3748766
