ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Continuous deployment of React websites to Amazon S3

This sample includes a continuous deployment pipiline for websites built with React. We use AWS CodePipeline, CodeBuild, and SAM to deploy the application. To deploy the application to S3 using SAM we use a custom CloudFormation resource.

Files included

buildspec.yml: YAML configuration for CodeBuild, this file should be in the root of your code repository
configure.js: Script executed in the build step to generate a config.json file for the application, this is used to include values exported by other CloudFormation stacks (separate services of the same application).
index.js: Custom CloudFormation resource that publishes the website to an S3 bucket. As you can see from the buildspec and SAM template, this function is located in a s3-deployment-custom-resource sub-folder of the repo
app-sam.yaml: Serverless Application model YAML file. This configures the S3 bucket and the cu

Use your Debian System as an iBeacon for Home Automation

Introduction

I have been playing with using the https://Home-Assistant.io system at home to play with Home Automation.

One thing I've found is that the Raspberry Pi is perfect for quite a few of the monitoring things that I wanted it to do (see also https://github.com/JonTheNiceGuy/home-assistant-configs for more details of what I'm doing there!).

I'm using the http://OwnTracks.org application to talk to an MQTT server, but I could also do with it knowing where I am in the house, so I looked around for some details on iBeacons.

iBeacon is an Apple standard, but it's very easy to configure on Linux systems. I took some pointers from this article and wrote up this script. When I later went to deploy this on another system, I also needed a pointer from [this PDF](https://cdn-learn.adafruit.com/downloads/pdf/pibeacon-ib

How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
VPC with NAT, The best of both worlds, AWS services and web.
