Writing Regular Expressions in #PowerShell like a Pro

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.

Using #PowerShell to talk to #Rancher

In my last post, I released several PowerShell modules to talk to several CI/CD tools. This includes Rancher a UI and orchestrator for containers.

Slide Deck (German): Continuous Delivery for Containerized Infrastructure Services

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.

Using the #Docker Named Pipe as a Non-Admin for #WindowsContainers

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.

Using #PowerShell to talk to #InfluxDB #InfluxData

In my last post, I released several PowerShell modules to talk to several CI/CD tools. This includes InfluxDB a time-series database which is part of the TICK stack by InfluxData for storing and analyzing monitoring data.

GUI no more... #PowerShell modules for several CI/CD tools

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?!

What's new in the #Docker Universe at #Container_Conf

Today, I had the opportunity to speak at ContainerConf in Mannheim. I talked about the news in the Docker ecosystem with a special focus on the Moby project. This post not only publishes my slides but also the demos from this talk.

Improving the Security of Privileged #Docker Containers

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.

Building a #WindowsContainer #Docker Host without running Windows Setup

At DockerCon I had the opportunity to talk about creating a Windows container host from scratch and how to maintain it when updates are published by Microsoft and Docker. Special thanks go out to Stefan Scherer. I realized that the official documentation assumes that a suitable system is already running. Existing work is often based on packer and vagrant which rely on an unattended installation, waiting for the VM to be accessible using WinRM and then injecting commands to finish the setup. I’d like to present how this is done the Microsoft way.

The Day after x-celerate #xcelerate2017

On 10-10-2017 our very own conference x-celerate took place at the trade fair in Freiburg, Germany. With well over 100 attendees, the feedback proved it was a success in its first year.
