☑️ Prevent workload from using the default namespace

The namespace default is a saved namespace value in which Kubernetes is deploying all objects without an explicit namespace. Using explicit namespaces instead of the default value makes for clearer boundaries between sets of pods in a cluster. For example, namespaces that represent teams present a clear organization of cluster resources and make configuration overlaps less likely.

Targeted resources by this rule (types of kind): Deployment / Pod / DaemonSet / StatefulSet / ReplicaSet / CronJob / Job

Enabled by default? True

Policy as code identifier: WORKLOAD_INCORRECT_NAMESPACE_VALUE_DEFAULT

If a workload has default set as the namespace name
