Kubernetes: Virtual Clusters For CI/CD & Testing

The use of virtual clusters (vClusters) in Kubernetes, i.e. running virtual clusters inside of physical clusters, has the potential to disrupt the use of Kubernetes in a variety of settings, from cloud-native development to machine learning experiments. (For an overview of the general benefits of virtual clusters and their use cases, refer to this article). One of these settings is continuous integration/deployment (CI/CD) and the related testing of software. In this post, I will describe how virtual clusters can be used for CI/CD and testing and what their benefits are for this use case. How virtual Kubernetes clusters can solve current issues of integrating Kubernetes in CI/CD and testing processes.
