                             configuration in YAML or JSON format.

  -n --namespace=<NS>        Namespace of the resource.
                             Only applicable to NetworkPolicy, NetworkSet, and WorkloadEndpoint.
                             Uses the default namespace if not specified.

Description:
  The patch command is used to patch a specific resource by type and identifiers in place.
  Currently, only JSON format is accepted.
  
  Valid resource types are:

    * bgpConfiguration
    * bgpPeer
    * felixConfiguration
    * globalNetworkPolicy
    * globalNetworkSet
    * hostEndpoint
    * ipPool
    * networkPolicy
    * networkSet
    * node
    * profile
    * workloadEndpoint

  The resource type is case insensitive and may be pluralized.
  Attempting to patch a resource that does not exists is treated as a
  terminating error unless the --skip-not-exists flag is set.  If this flag is
  set, resources that do not exist are skipped.
  
  When patching resources by type, only a single type may be specified at a
  time.  The name is required along with any and other identifiers required to
  uniquely identify a resource of the specified type.
