When it comes to managing Kubernetes packages, Helm is currently the only option available. Although some people may dismiss its capabilities in favor of other options, the truth is that Helm's templating skills are unmatched. Other formatting solutions for Kubernetes suffer from inconsistent output, which can make it challenging to manage applications in the cluster effectively. Unlike other options, Helm keeps track of the entire application and its relevant data within the cluster, making it easier to manage and monitor applications even after deployment.
The Absence of Helm Anti-Pattern:
Without Helm, managing applications in a Kubernetes cluster can become a nightmare. A basic templating solution like customize may work during application deployment, but once the process is complete, Kubernetes is left with only a collection of manifests, making it difficult to manage or remove applications. With Helm, it's easy to monitor and manage applications within the network using simple commands like helm ls and helm uninstall my-release. Even if you don't have access to the original templates or a CI pipeline, Helm allows you to revert to a previous state with a simple click of a button, making it a valuable tool for any Kubernetes administrator.
Since the release of Helm 3, the server-side component (Tiller) is no longer required, making it a more secure option for cluster management. While some may believe that there are better templating options than Helm, it's essential to make an informed decision based on its unmatched capabilities and advantages over other options. For example, Helm charts should be maintained in dedicated Helm repositories and distributed using the Helm repository, not the Git repo.
Ignoring Helm in Kubernetes package management can lead to significant problems for administrators. With its templating skills, monitoring capabilities, and the ability to revert to a previous state, Helm is a critical tool for managing applications in a Kubernetes cluster effectively. While some may overlook its importance in favor of other options, the reality is that there is no better option than Helm for Kubernetes package management.
