Resource Definitions using the Echo Driver

This section contains example Resource Definitions using the Echo Driver.

Namespace

This section contains example Resource Definitions using the Echo Driver for managing Kubernetes namespaces.

  • custom-namespace.yaml: Shows how to use the Echo Driver to return the name of an externally managed namespace. This format is for use with the Humanitec CLI.
  • custom-namespace.tf: Shows how to use the Echo Driver to return the name of an externally managed namespace. This format is for use with the Humanitec Terraform provider.
