Namespace selector
A namespace selector is a label-based configuration that identifies Kubernetes namespaces matching specified labels.
Google Anthos in Action
A NamespaceSelector is an Anthos Config Management object that selects namespaces by matching their Kubernetes labels.
- How it is used
- Targets namespace-scoped ACM configurations through namespace labels instead of assigning each configuration to a single named namespace.
- How deep it goes
- Shows selector YAML, annotation-based use, and repository-mode restrictions; does not explain selector reconciliation internals.
- Examples
- Uses a production-label selector and annotated developer Role, plus a selector targeting a Config Connector project namespace.
- What you can do after
- Operate/configure it: define a label-matching selector and reference it from namespace-scoped objects while accounting for repository mode.

A namespace selector is a label-based selector that identifies namespaces whose pods may be included in a network policy rule.
- How it is used
- Controls pod traffic in NetworkPolicy ingress and egress rules by narrowing allowed connections to selected namespaces.
- How deep it goes
- Explains selector composition and OR-versus-AND behavior, but does not provide a standalone namespace-selector manifest.
- Examples
- Uses frontend pods in myproject accessing db pods in default alongside CIDR exceptions and TCP port restrictions.
- What you can do after
- Evaluate NetworkPolicy rules and configure namespace-scoped traffic permissions with selector combinations.
