 This chart deploys the Anchore Enterprise container image analysis system. Anchore requires a PostgreSQL database (>=9.6) which may be handled by the chart or supplied externally, and executes in a service-based architecture utilizing the following Anchore Enterprise services: External API, SimpleQueue, Catalog, Policy Engine, Analyzer, GUI, RBAC, Reporting, Notifications and On-premises Feeds. Enterprise services require a valid Anchore Enterprise license, as well as credentials with access to the private DockerHub repository hosting the images. These are not enabled by default.
