Multi Namespace

Multi-namespace deployment lets a single Redis Enterprise operator manage clusters and databases in different namespaces, providing better resource isolation and organization.

Multi-namespace deployment enables:

• Namespace isolation: Separate Redis Enterprise resources by team, environment, or application
• Centralized management: Single operator manages multiple namespaces
• Resource sharing: Efficient use of cluster resources across namespaces
• Flexible RBAC: Fine-grained permissions per namespace

This example shows:

• Operator namespace: redis-enterprise-operator (where the operator and REC run)
• Consumer namespaces: app-production, app-staging (where REDB resources are created)

For complete deployment instructions, see [Manage databases in multiple namespaces]({{< relref "/operate/kubernetes/7.22/re-clusters/multi-namespace" >}}).

Operator service account

Deploy these resources in the namespace where the Redis Enterprise operator runs.

{{<embed-yaml "k8s/service_account.md" "operator-service-account.yaml">}}

Operator cluster role

Grant the operator cluster-wide permissions to manage resources across namespaces.

{{<embed-yaml "k8s/multi-ns_operator_cluster_role.md" "operator-cluster-role.yaml">}}

Operator cluster role binding

{{<embed-yaml "k8s/multi-ns_operator_cluster_role_binding.md" "operator-cluster-role-binding.yaml">}}

Consumer role

{{<embed-yaml "k8s/multi-ns_role.md" "consumer-role.yaml">}}

Consumer role binding

{{<embed-yaml "k8s/multi-ns_role_binding.md" "consumer-role-binding.yaml">}}

Consumer namespace configuration:

• subjects.name: Must match the operator service account name
• subjects.namespace: Must be the operator namespace, not the consumer namespace
• roleRef.name: Must match the consumer role name
