Open Sourcerers
In this post, I am going to show you how to enable faster Podman builds in Eclipse Che / OpenShift Dev Spaces by enabling support for /dev/fuse in your workspace. This will eliminate the need for using vfs with podman. It also gets us closer to being able to do podman run in a rootless […]

The tutorial is divided into the following sections: If you are not interested in the possible use cases and would rather start right away, […]

Introduction In my previous post on Open Source and Quantum Computing Quantum Computing: Open Source from the Start we learned about Quantum Computing in general and how Open Source is used to provide access to this new computing paradigm. This post will now focus on how to get started and provide a very easy guide […]
Part two of the article series. This time about Helm Charts, Operators and various CLI tools to work with container images.
Docker came a long way. It established itself very fast as the de-facto standard to get going with your container journey. It did not matter if you wanted to just play around with containers or if you wanted to build up new microservices, Docker was and still is a great choice to get yourself started. […]

I have worked with container images more or less since 2015 but during an OpenShift 4 air-gapped installation and mirroring of images into […]
