Set up microk8s with Cilium for development

Microk8s is a Canonical project to provide a kubernetes environment for local development, similar to minikube but without requiring a separate VM to manage. These instructions describe setting it up for common development use cases with Cilium and may be helpful in particular for testing BPF kernel extensions with Cilium.

Microk8s will run its own version of docker for the kubernetes runtime, so if you have an existing docker installation then this may be confusing, for instance when building images the image may be stored with one of these installations and not the other. This guide assumes you will run both docker daemon instances, and use your existing docker-ce for building Cilium while using the microk8s.docker daemon instance for the runtime of your kubernetes pods.

Requirements

• Linux with kernel 4.9 or newer ([Full Cilium Requirements](https://cilium.readthedocs.io/en/latest/install/system_requirements/?highlight=requiremen

Why Tcl?

Introduction

I use [Tcl] as my scripting language of choice, and recently someone asked me why. This article is an attempt to answer that question.

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).

# set an env var to the path to a config
export REGTEST_CONFIG=$HOME/.config/hsd/regtest.conf

# this assumes you have git cloned and npm installed handshake
# be sure to start your handshake node with the same config

# the cli tools live in node_modules/.bin

backup dotfiles

• Following will copy all of dot ~/. files and directories (including its contents) directly underneath home directory.
• To avoid copying cache and other local configs, e.g., that of web browser, java apps, etc., preferably query directory size tool under entire home $HOME/, using ncdu $HOME of similar tool.
• Exclude all those large directories using rsync --exclude=.local --exclude=.cache format
• Avoid rsync password, ssh keys, .bash_history, etc. if you are uploading to github, etc.
• rsync home dotfiles and configs as follows:
