Hardcoding a proxy server is an anti-pattern and you are probably aware of this. But how do you handle it when your PowerShell code is executed in different environment with and without a proxy server. You certainly do not want to add parameters for this because this would only be the beginning.
$PSDefaultParameterValues to the rescue!

Regular expressions are often considered the holy grail of parsing data. Regexes are very powerful but most of them are unreadable as well as seldomly documented. But with great power comes great responsibility. I will demonstrate how to write complex regular expressions, make them readable and even include proper documentation.

In mid-December I had the opportunity to talk at a German conferences called IT-Tage held in Frankfurt. The event was organized by Informatik Aktuell. In my talk I described how traditional infrastructure services can profit from containerization and continuous delivery as well as which challanges arise when automating the deployment as a scalable, highly available service.

When using Windows containers you will quickly notice that Docker on a Windows Server requires an elevated prompt to use the named pipe at
\\.\pipe\docker_engine. Today I will demonstrate how to change the permissions of the named pipe to have a similar UX as on Linux.

I am a console guy, you know. Although a graphical user interface (GUI) is a great way to visualize data, it often falls short of its potential when it does not correlate data. That’s when a command line tool comes into play. It enables you to retrieve different kinds of data and process them yourself. And since, I love PowerShell, what better way than replacing GUIs using cmdlets?!

Privileged containers have been the reason for many discussions. There are security minded people who would like to eliminate them as well as technical people who need the feature to drive containerization. I’d like to show you how to be a technical person running a privileged container but honour security considerations by dropping capabilities as soon as they are not required.
