I run probably more than a hundred kubectl commands on some days, as you can tell I like to try out things. After a while I started to notice some patterns and realized I can pretty much condense 99% of all my kubectl usage into single-word bash aliases.

Securing Docker with HTTP Basic Authentication Ahmet Alp Balkan published on 13 October 2014 I recently needed to secure my Docker host instance simply with a basic username and password authentication as I mostly find the certificate creation steps tedious. Docker has no built-in username/password authentication support so I thought I could have a HTTP proxy server which asks for a password on to
