Container Service for Kubernetes (ACK) integrates the package manager Helm to help you deploy applications to the cloud in an efficient manner. You can install a chart multiple times in a Kubernetes cluster. Each time you install a chart, a release is created. This requires you to manage release versions. To meet this requirement, ACK provides the release feature that allows you to manage applications deployed by using Helm in the ACK console.
