Handling File Permissions When Writing to Volumes from #Docker Containers

Containers are often used as a replacement for a natively installed tool. It is much cleaner to use a container with the required version instead of having an outdated tool on the host. But as soon as the container interacts with the host system, file are left with wrong or broken permissions. Fortunately, the solution does not require scripting.

Article about managing container environments in German #Docker

I have recently published a article in Informatik Aktuell - a German online magazine for IT. I wrote about managing container environments using Continuous Integration and Continuous Delivery. I also stated that IT administrators can learn a lot about agility from software developers.

What I consider to be Professional #PowerShell

I have recently held several PowerShell introductions and had exciting discussions about coding style and things considered to be professional in PowerShell. I decided to collect those thoughts. The presentation grew to a point where I decided to publish it.

Setting a Proxy without changing your #PowerShell Code

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!

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.
