The two package management tools that can be used to configure and install applications on Kubernetes are Carvel and Helm. Helm is well-known for being a package manager for Kubernetes, allowing users to define, install, and upgrade even the most complex Kubernetes applications. Similarly, Carvel provides a set of tools for building, configuring, and deploying applications on Kubernetes. Other tools listed, such as Grafana, Fluent bit, and Multus, serve different purposes such as monitoring, logging, and networking respectively, and are not primarily package management tools.
