What is Helm?

Micro-service and containerization bring great challenges to the deployment and management of complex applications. Helm is currently the only open source sub-project in the field of Kubernetes service orchestration. As a package management tool for Kubernetes applications, it can be understood as Kubernetes's apt-get / yum, initiated by Deis, which has been acquired by Microsoft. Through the form of software packaging, Helm supports release version management and control, which greatly simplifies the complexity of Kubernetes application deployment and management.

Use of Helm

As a package management tool for Kubernetes, Helm has the following functions:

Create a new chart

Chart is packaged into tgz format

Upload chart to chart repository or download chart from warehouse

Install or uninstall chart in a Kubernetes cluster

Manage the release cycle of chart installed with Helm

Helm has three important concepts:

Chart: contains the necessary information to create an application instance of Kubernetes

Config: contains application release configuration information

Release: is a running instance of chart and its configuration
