Deploying openfaas cloud on armhf

Prerequisites

A domain name which can point to your deployment. (subdomain names also work)
Setup Github app. Refer this. You'll need to transfer the downloaded private-key.pem file to arm device.
Docker hub account.

Core components steps:

Sign in to docker hub on your machine using:

Redis & OpenFaaS micro-tutorial

After you've completed this micro-tutorial you'll be making requests to your Redis cache from serverless functions with OpenFaaS. From there it's up to you to build something awesome.

Pre-reqs:

Deploy OpenFaaS and the faas-cli.

This guide is for OpenFaaS on Kubernetes, but if you're using Swarm that's OK - you'll just have to adapt some of the commands for setting up Redis. The OpenFaaS code will be the same.

OpenFaaS Cloud Community Cluster

Apply for early acccess.

We've moved 👋

Start here: https://github.com/openfaas/community-cluster

The OpenFaaS documentation for faas-netes gives a clear explanation of how to install with Helm, but Pivotal Container Service (PKS) has 2 caveats since provisoned Kubernetes clusters are non-RBAC but are token backed and LoadBalancer inclusion with NSX-T. This is going to be a quick streamline of the documentation that adds out of the box support for PKS.

$ curl https://raw.githubusercontent.com/kubernetes/helm/master/scripts/get | bash
$ kubectl -n kube-system create sa tiller && kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
$ helm init --skip-refresh --upgrade --service-account tiller
$ kubectl apply -f https://raw.githubusercontent.com/openfaas/faas-netes/master/namespaces.yml
$ helm repo add openfaas https://openfaas.github.io/faas-netes/
$ helm repo update && helm upgrade openfaa

Installing cloud-init on a fresh Raspbian Lite image

This is a work in Progress!

Purpose

This mainly demonstrates my goal of preparing a Raspberry Pi to be provisioned prior to its first boot. To do this I have chosen to use the same cloud-init that is the standard for provisioning servers at Amazon EC2, Microsoft Azure, OpenStack, etc.

I found this to be quite challenging because there is little information available for using cloud-init without a cloud. So, this project also servers as a demonstration for anyone on any version of Linux who may want to install from source, and/or use without a cloud. If you fall into that later group, you probably just want to read the code. It's bash so everything I do, you could also do at the command line. (Even the for loop.)
