minikube, macOS and virtualbox

Friday, October 11th, 2019

minikube is an awesome tool to play around with Kubernetes and it’s easy to install on macOS if you already have brew installed (not much harder if you just follow the instructions on kubernetes.io though)

But sometimes, just sometimes…. spinning up a Kubernetes cluster with minikube does not work… it gets stuck somewhere. You can crank up the debug level which will fill your screen your message and you can searchengine whatever error message it spits out and try to fix it. I’ve tried it but it takes and usually does not bear frut. In the end doing the following always fixed the issues:

shutdown any minikube clusters that are running (on purpose or not)
make sure virtualbox is turned off (when in doubt, check with ps aux | grep -i virtualb )
rm -rf .minikube
rm -rf .kube
brew cask reinstall virtualbox
if you’re feeling adventerous, you can upgrade minikube and kubectl at the same time.
then spin up minikube again: minikube start -p <yourclusternamehere> (I like not using the default cluster)

IT Security for home users – keep your applications up to date

Windows

ninite

My personal suggestion is ninite, to be found at https://ninite.com/

Select the applications you want to use, download the installer and run it only a daily basis – it will keep you up to date and safe(r)

MacOS

AppStore

Love it or hate it, but minor applications can easily be installed via the AppStore e.g. Line or Slack

Advantage: You will get an update notification from the AppStore if an update is available

Brew

Follow the instructions on the brew HP: https://brew.sh/

Once this is done, you can install, update or uninstall applications from the command line

Installs

brew install wget

brew cask install macvim

brew cask install gimp

brew cask install libreoffice

brew cask install quodlibet

brew cask install virtualbox

brew cask install chromium

brew cask install projectlibre

brew cask install vlc

brew cask install skype

brew cask install minikube

brew cask install firefox

brew cask install keepassx

brew cask install box-sync

Uninstall

brew cask uninstall <cask_name>

Upgrade

brew update && brew outdated && brew upgrade && brew cleanup

IT Security for home users – upgrade your OS

Thursday, February 28th, 2019

The mainstream operation systems (including mobile OSes) have an upgrade function (in case of a mobile OS, whether your carrier releases updates is a different story….)

Use that function and install those updates!

macOS: Go to the Apple icon, select “About This Mac” and click on “Software Update…” Most of the updates require a reboot, even on MacOS.

Windows: From the “Windows Settings”, go to “Update & Security”. Check for updates, install what’s available and reboot.

Ubuntu: Run ‘sudo apt-get update && apt-get dist-upgrade’
(if you feel like protesting because <your valid reason here>, then you already know what you’re doing and you shouldn’t be reading this anyway (unless you want to fact-check my ramblings))
Other Linux versions use different commands, if you’re unsure, google for the appropriate command on your platform.
