Setup Kubernetes cluster in minutes using Talos

1. Get talosctl

Download and install talosctl binary

wget https://github.com/talos-systems/talos/releases/download/v0.8.1/talosctl-linux-amd64

This was initially posted in an kubernetes-sigs/kustomize issue.

We are using Kustomize's vars feature. Initially we didn't understand how to use it for our purpose, but it is a 100% fit. One example is our Ingress resource, which looks like this:

# file: base/ingress.yaml
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: services

Talos on Firecracker

Build Firecracker from source (it's fast and easy, builds in docker): https://github.com/firecracker-microvm/firecracker/blob/master/docs/getting-started.md#building-from-source
Adjust /dev/kvm permissions: https://github.com/firecracker-microvm/firecracker/blob/master/docs/getting-started.md#prerequisites
Build Talos, you will need build/vmlinux & build/initramfs.xz.
Prepare configs for Talos: osctl config generate fire https://172.16.0.2:6443. Make following changes to the config: add resolvers to the machine.network config: nameservers: ["8.8.8.8", "1.1.1.1"] (IP config will come from kernel args), update install location: install: disk: /dev/vda (default is sda).

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

Originally, I had included some other solution

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.
