A Helm chart is a package containing files, templates, and other resources necessary to deploy an application to a Kubernetes cluster. When a CalypsoAI Helm chart is deployed, the default parameters set in the Helm chart will deploy the application in a configuration that is suitable for most use cases. However, it may be necessary to use additional parameters to fine tune a deployment to meet the needs of a specific workload.
