When authenticating against a container registry, the user only supplies username and password. But in the background, Docker daemon and registry are using token authentication. This post demonstrates how to build a registry with a separate authentication service for token authentication.
This week I had the honour of giving a talk at the Docker Virtual Meetup about how to improve your Docker image builds. It was a very interactive crowd :-)
There has been much confusion around the container entrypoint and parameters. This post will shed some light on this topic and present an script to serve as an flexible entrypoint.
For the third time in a row, I co-organized a regional IT conference called x-celerate held in Freiburg, Germany. This time, I contributed a talk about covering the following topics:
Last week I had the chance to talk about observability at our local Devsmeetup. As usual, after the talk we had a very lively discussion about monitoring in general but also about Prometheus and long term storage.
Last week I had the honour of talking again at ContainerConf 2019 in Mannheim. I consider this conference to be the best German event in the container space. Just like in the two previous years I talked about news with regard to containers. But this year, I decided to stop focussing on Docker but covered Kubernetes as well.
When working with Kubernetes for the first time, the concept of a pod feels strange because Docker has not prepared us for it ;-) But the idea of a pod can be useful when working with Docker. This post will demonstrate how to use a pod to deploy isolated environments for workshops.
In a workshop situation, attendees must be able to follow the material in a personal hands-on environment. Docker helps isolating such environments and prevents issues from using the attendees’ laptop. Let me show you how to provide dedicated environments using shellinabox.
I had the honour to contribute two workshops about Docker to an called Sommercampus held by the faculty of engineering of the university Freiburg:
The demos are part of the slides.
I am very happy to announce that I have been awarded Microsoft Most Valuable Professional (MVP) in Cloud and Datacenter Management again.
Thank you, Microsoft, for recognizing my contributions to the community.
