Helm is a templating packaging and deployment manager for Kubernetes that simplifies the management of Kubernetes applications by providing a simple, easy-to-use place to define, install, and upgrade complex applications. Helm charts are collections of files that describe related groups of Kubernetes resources, including metadata, templates, and values files. To create a Helm chart, one can use the `helm create` command, which generates a chart directory with common files and directories. The process of creating and updating Helm charts is straightforward, allowing developers to easily manage their applications and deploy them in any environment. With Helm, developers can create complex applications that include servers, caches, and more, making it an essential tool for Kubernetes users.
