As previously discussed, all the actions that we carry out on the Kubernetes cluster are done via the kubectl tool and the YAML specification files.
In a company that deploys several microservice applications on a K8S cluster, we often notice a large number of these YAML specification files, and this poses a maintenance problem. In order to solve this maintenance problem, we can use HELM, which is the package manager for Kubernetes.
