Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

Kubernetes on (vanilla) Raspbian Lite

Yes - you can create a Kubernetes cluster with Raspberry Pis with the default operating system called Raspbian. This means you can carry on using all the tools and packages you're used to with the officially-supported OS.

Pre-reqs:

You must use an RPi 2 or 3 for use with Kubernetes
I'm assuming you're using wired ethernet (Wi-Fi also works, but it's not recommended)

Security Tools for AWS

I often get asked which tools are good to use for securing your AWS infrastructure so I figured I'd write a short listof some useful Security Tools for the AWS Cloud Infrastructure.

This list is not intended be something completely exhaustive, more so provide a good launching pad for someone as they dig into AWS and want to make it secure from the start.

Open Source

This section focuses on tools and services provided by the community and released as open-source.

AWS Setup

1. Create AWS role called Spinnaker with proper access.
2. run aws configure and set your keys/secret.

Install Git and NVM

sudo apt-get -y install git
git clone https://github.com/spinnaker/spinnaker.git
