title: Workload Endpoint Resource (WorkloadEndpoint)

---

A workload endpoint resource (`WorkloadEndpoint`) represents an interface
connecting a Calico networked container or VM to its host.

Each endpoint may specify a set of labels and list of profiles that Calico will use
to apply policy to the interface.

A workload endpoint is a namespaced resource, that means a
[NetworkPolicy]({{site.baseurl}}/{{page.version}}/reference/calicoctl/resources/networkpolicy)
in a specific namespace only applies to the WorkloadEndpoint in that namespace.
Two resources are in the same namespace if the namespace value is set the same
on both.

For `calicoctl` [commands]({{site.baseurl}}/{{page.version}}/reference/calicoctl/commands/) 
that specify a resource type on the CLI, the following aliases are supported (all case 
insensitive): `workloadendpoint`, `workloadendpoints`, `wep`, `weps`.

> **Note**: While `calicoctl` allows the user to fully manage Workload Endpoint resources,
> the lifecycle of these resources is generally handled by an orchestrator-specific
> plugin such as the Calico CNI plugin. In general, 
> we recommend that you only use `calicoctl` to view this resource type.
