Namespaces are Kubernetes' built-in way to organize and isolate resources inside a single cluster. They’re commonly used to separate teams, environments, or applications, and they pair naturally with RBAC and quota policies to reduce the blast radius of mistakes.
In the full tutorial, we cover:
- What namespaces are (and what they don’t isolate)
- Default namespaces you’ll see in most clusters
- How to create namespaces and apply resources to them from YAML or kubectl
- Listing, switching, and troubleshooting namespace-related issues
- Practical patterns for teams (dev/stage/prod separation, multi-tenant clusters)
