This is a fourth post in a series, describing the problems my team has faced during implementation of Jenkins pipelines in Kubernetes. Jenkins Java Centric Pipelines in Kubernetes Building Maven Projects in Jenkins Docker workers Using Maven and Jenkins to perform modular Java builds Building Docker Images in Jenkins on Kubernetes (This article) Why would we want to build Docker images in Kubernetes Often Kubernetes is the platform of choice both for the production environments and the CI(/CD) pipelines that we use for our development processes. Since Docker images are the basic building blocks, we must be able to build them from within our Kubernetes hosted pipeline. ......

This is a third post in a series, describing the problems my team has faced during implementation of Jenkins pipelines in Kubernetes. Jenkins Java Centric Pipelines in Kubernetes Building Maven Projects in Jenkins Docker workers Using Maven and Jenkins to perform modular Java builds (This article) Building Docker Images in Jenkins on Kubernetes Modular Maven builds in stateless Jenkins workers Maven is a pretty smart piece of software. Among its many capabilities it knows to build only the modified code since the last build (unless you run the “clean” directive. When building in a stateless Jenkins workers for the reasons stated in the previous post, we lose these abilities, since every builds starts with an empty workspace. ......

This is a first post in a series, describing the problems my team has faced during implementation of Jenkins pipelines in Kubernetes. Jenkins Java Centric Pipelines in Kubernetes (This article) Building Maven Projects in Jenkins Docker workers Using Maven and Jenkins to perform modular Java builds Building Docker Images in Jenkins on Kubernetes When I took this project, I’ve read a considerable number of guides and documentation pages, some of them official, others written by bloggers like me. The common theme was to show a single aspect of the project. This approach simplifies the effort to explain the solution, however ignores the biggest challenge: combining the various solutions together. ......
