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

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.

Kubernetes and Arm

Getting rke and Rancher setup to run kubernetes on arm is interesting. There is no official support yet via rancher, although there is interest and some work done towards those efforts. This is my attempt at getting a cluster of 3 Pis (2 3Bs and 1 3B+) provisioned and registered to a rancher 2 server.

Prep

I've successfully completed this both with Hypriot OS 1.9.0 and the arm64 builds https://github.com/DieterReuter/image-builder-rpi64 Both times I used the same basic cloud-init setup

Utilities you'll care about

All these are already installed on epyc.

• kafkacat (conda install -c conda-forge kafkacat)

• kt (grab it from https://github.com/fgeller/kt/releases)

• kafka-* (come with kafka, if you yum install if from Confluent's repo, or via Docker if you're so inclined). Warning -- JVM based and dreadfully slow.

• jq (conda install -c conda-forge jq or use your favorite package manager)
