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

  • custom-namespace.yaml: Create Kubernetes namespaces with your own custom naming scheme. This format is for use with the Humanitec CLI .
  • custom-namespace.tf: Create Kubernetes namespaces with your own custom naming scheme. This format is for use with the Humanitec Terraform provider .
  • short-namespace.yaml: Create Kubernetes namespaces with your own custom naming scheme of defined length. This format is for use with the Humanitec CLI .
