Managing Kubernetes Resources with Kustomize

Helm is the de-facto standard for managing groups of Kubernetes resources that belong to an application as a package.

In some cases, this is an appropriate approach but sometimes we just want to manage our resources as yaml files and need a simple way to slightly modify the resources for different environments. In this article we will have a look at how Kustomize can help us with this.

Libraries for command-line applications

Command-line applications are admittedly not the most common due to the start time of the JVM. Their development for internal applications can however be appropriate, depending on the level of knowledge of the team. And thanks to the native compiling with GraalVM, the start time is accelerated. Much of the work involved in a command-line application involves parsing and use of the provided arguments and options. We look at four possible libraries that can assist us.

Awesome presentations deserve beautiful code

Occasionally we need to put parts of our source code onto slides for presentations. The common presentation programs (such as PowerPoint or Keynote) fail miserably at this task because they interpret code as normal text. Syntax highlighting is lost, as are indentations. It looks lousy, and it’s no fun. This post introduces carbon.now.sh, a quick and free solution, created by the awesome people from @carbon_app.

Software quality in the context of value chains and evolution

Quality goals help to make more informed architectural decisions. However, identifying a set of the most needed qualities is a challenging task. Quality requirements are strongly dependent on the perspective of individuals. The importance of certain qualities also changes over time. In this blog post, I introduce an idea that helps to understand qualities in terms of their relevance (and non-relevance). We discover how qualities interplay with value creation activities and evolution by using the ISO 25010 quality model together with Wardley Maps as a foundation.
