What namespaces scope
Workload commands use a namespace when creating, listing, updating, or deleting workload resources. Examples of namespace-scoped resources include deployments, jobs, cron jobs, replica sets, and pods. A Workspace is created within one Namespace. Workspace names are unique within that Namespace, so its full user-facing address is<namespace>/<workspace>.
Namespace and subnet
Namespaces and subnets are separate concepts.
A direct Workload is scoped to a Namespace and placed on a Subnet. It does not
require a Workspace. A Workspace Run composes a Workload in the Workspace’s
enclosing Namespace.
