Automatic configuring of vlan and overlay logical switches for container secondary interfaces

Abstract

The method of some embodiments allocates a secondary network interface for a pod, which has a primary network interface, in a container network operating on an underlying logical network. The method receives an ND that designates a network segment. The method receives the pod, wherein the pod includes an identifier of the ND. The method then creates a secondary network interface for the pod and connects the secondary network interface to the network segment. In some embodiments, the pods include multiple ND identifiers that each identify a network segment. The method of such embodiments creates multiple secondary network interfaces and attaches the multiple network segments to the multiple secondary network interfaces.

         9 . A method for configuring a pod, the method comprising:
 performing an automated process to associate the pod with at least two network segments, said performing comprising:
 detecting deployment of the pod associated with a first network segment, said pod having a default primary interface for connecting to the first network segment; 
 from a definition of the pod, determining that the pod is to be associated with a second network segment; 
 identifying a secondary interface for the pod; and 
 associating the secondary interface with the pod and the second network segment, said secondary interface allowing the pod to communicate with the second network segment. 
   
     
     
         10 . The method of  claim 9 , wherein said determining comprises:
 receiving a network attachment definition (NAD) that designates a network segment; and   determining that the pod definition includes an identifier of the NAD;   
     
     
         11 . The method of  claim 10 , wherein identifying the secondary interface comprises creating the secondary network interface for the pod based on the determination that the pod definition includes the identifier of the NAD. 
     
     
         12 . The method of  claim 10 , wherein the NAD designate a pre-created network segment. 
     
     
         13 . The method of  claim 10 , wherein the NAD designates attributes of a network segment that the automated process needs to dynamically deploy and to associate the secondary interface with this dynamically deployed network segment. 
     
     
         14 . The method of  claim 13 , wherein the dynamically deployed network segment is a VLAN (virtual local area network) segment or an overlay network segment. 
     
     
         15 . The method of  claim 10 , wherein the pod definition references a plurality of identifiers for a plurality of NADs to indicate that the pod has a plurality of secondary network interfaces attached to a plurality of network segments. 
     
     
         16 . The method of  claim 10 , wherein the NAD comprises a name that is used to identify a network attachment. 
     
     
         17 . The method of  claim 10 , wherein the NAD comprises a number or code identifier that identifies the network attachment. 
     
     
         18 . The method of  claim 9 , wherein said secondary network interface serves as high-performance interface for data traffic. 
     
     
         19 . A non-transitory machine readable medium storing a program which when executed by at least one processing unit configures a pod, the program comprising sets of instructions for:
 detecting deployment of the pod associated with a first network segment, said pod having a default primary interface for connecting to the first network segment;   from a definition of the pod, determining that the pod is to be associated with a second network segment;   identifying a secondary interface for the pod; and   associating the secondary interface with the pod and the second network segment, said secondary interface allowing the pod to communicate with the second network segment.   
     
     
         20 . The non-transitory machine readable medium of  claim 19 , wherein the set of instructions for said determining comprises sets of instructions for:
 receiving a network attachment definition (NAD) that designates a network segment; and   determining that the pod definition includes an identifier of the NAD;   
     
     
         21 . The non-transitory machine readable medium of  claim 20 , wherein the set of instructions for identifying the secondary interface comprises a set of instructions for creating the secondary network interface for the pod based on the determination that the pod definition includes the identifier of the NAD. 
     
     
         22 . The non-transitory machine readable medium of  claim 20 , wherein the NAD designate a pre-created network segment. 
     
     
         23 . The non-transitory machine readable medium of  claim 20 , wherein the NAD designates attributes of a network segment that the automated process needs to dynamically deploy and to associate the secondary interface with this dynamically deployed network segment. 
     
     
         24 . The non-transitory machine readable medium of  claim 23 , wherein the dynamically deployed network segment is a VLAN (virtual local area network) segment or an overlay network segment. 
     
     
         25 . The non-transitory machine readable medium of  claim 20 , wherein the pod definition references a plurality of identifiers for a plurality of NADs to indicate that the pod has a plurality of secondary network interfaces attached to a plurality of network segments. 
     
     
         26 . The non-transitory machine readable medium of  claim 20 , wherein the NAD comprises a name that is used to identify a network attachment. 
     
     
         27 . The non-transitory machine readable medium of  claim 20 , wherein the NAD comprises a number or code identifier that identifies the network attachment. 
     
     
         28 . The non-transitory machine readable medium of  claim 19 , wherein said secondary network interface serves as high-performance interface for data traffic.
