Description

Use this key to identify the tenant in a multi-tenant environment. The tenant ID uniquely identifies an organization, customer, or isolated group within a shared infrastructure.

This key is particularly relevant for SaaS (Software as a Service) applications and platforms where multiple customers share the same pool of infrastructure while maintaining logical isolation.

This key enables tenant isolation, resource quotas, and access control policies for cloud native workloads and platforms.

The value should be a valid Kubernetes label value (alphanumeric characters, hyphens, underscores, and periods; maximum 63 characters). However, this is not formally a validation requirement.

Here’s an example manifest for a Namespace in Kubernetes. Typically you would use a controller to define a namespace based on automation:

---
apiVersion: v1
kind: Namespace
metadata:
  name: my-tenant-namespace
  labels:
    tenancy.native.cloud/tenantID: "tenant-12345"
  annotations:
    kubernetes.io/description: "Namespace for tenant-12345 (ACME Corporation)"

Example Values

tenant-12345

org-acme-corp

customer-uuid-a1b2c3d4
