Deploying Kubernetes 1.11 on DigitalOcean with Rancher 2.0

This guide will help you add support for DigitalOcean volumes and load balancers to a freshly deployed Kubernetes 1.11 cluster. It assumes you already have a cluster deployed through Rancher, have kubectl set up, and helm installed.

Set up helm

kubectl apply -f helm-rbac.yaml
helm init --service-account tiller

helm-rbac.yaml:

Here's how you could create custom error classes in Node.js using latest ES6 / ES2015 syntax.

I've tried to make it as lean and unobtrusive as possible.

Defining our own base class for errors

errors/AppError.js

	module.exports = {
	presets: [
	'@babel/react',
	],
	plugins: [
	'@babel/proposal-class-properties',
	[ '@babel/proposal-decorators', { legacy: true }],
	'@babel/proposal-do-expressions',
	'@babel/proposal-export-default-from',
	'@babel/proposal-export-namespace-from',

	// Compile with: cl.exe appinitdllinjection.c /LD /o appinitdllinjection.dll
	//
	// This DLL can only be injected in a x64 process
	//
	// Set the registry to automatically load this DLL into 'any' process that is started (at least the ones relying on User32.dll)
	// by using the AppInit_DLLs capability:
	//
	// HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs = 'path_to_the_dll' (comma or space separated if required)
	// One trick with this registry entry is to separate DLLs with an hex '00' (by editing the value in binary) to hide the DLL name
	//
