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 .
