There are 2 CRDs included in the namespace management now.

1. NamespaceTemplate (nt)

2. ManagedNamespace(mns)

3. NamespaceTemplate provides following in high level exportedParams NamespaceResources Namespace Resources

   • Name Type DependsOn: CreateOnly OneOf{ ServiceAccount Role RoleBinding ResourceQuota }
   • Name Type DependsOn: CreateOnly OneOf{ ServiceAccount Role RoleBinding ResourceQuota }

ExportedParams: Params which can to be replaced runtime and should use ${param} in the manifests

DependsOn: By default, Namespace will be created first and any resources under Resources section will be created in parallel. To control the dependency structure one can use DependsOn parameter to force the execution only once its dependent resource has been created.

CreateOnly: If any resource needs to be created only once and should not be overwritten can use CreateOnly parameter to enforce it.

Resource: Type should dictate what Resource being included in the resource section and any other resource manifests included in that resource section will be ignored. For ex: To create a service account, Type should be ServiceAccount and should include serviceAccount: section

2. ManagedNamespace provides following in high level clusterName params: templateName: NamespaceResources Namespace Resources
   • Name Type DependsOn: CreateOnly OneOf{ ServiceAccount Role RoleBinding ResourceQuota }
   • Name Type DependsOn: CreateOnly OneOf{ ServiceAccount Role RoleBinding ResourceQuota }.

clusterName: Name of the cluster in which this namespace needs to be created

params: map[string]string - this should be used to provide the runtime values for the exportedParams for the namespace template

templateName: Name of the namespace template to be used for this and namespace template must exists. Optional

NamespaceResources: Additional resources to be created in addition to the template provided and can also be used to create namespace directly without using template.

Could you share the test results?
