Method of container cluster management and system thereof

1 . A method for use in a container cluster management element, the method comprising:

generating a container cluster instance based on a container cluster descriptor (CCD) template, wherein the container cluster instance comprises at least one master node and at least one work node,

deploying the at least one master node as at least one container infrastructure service manager (CISM) and deploying the at least one work node as at least one container infrastructure service instance (CISI), and

transmitting, to a management element, the container cluster instance for use in a life cycle management operation of at least one virtual network function,

wherein the CCD template comprises cluster attribute information, and

wherein the cluster attribute information comprises at least one of a cluster name, a version or resource information, for efficient management of cluster resources for the life cycle management operation.

2 . The method of claim 1 , further comprising:

receiving a cluster generation request of generating the container cluster instance from at least one of the management element, an operation support system (OSS) or a third party, wherein the cluster generation request comprises an identification of the CCD template, or

receiving a request for a management of the container cluster instance, wherein the request for the management of the container cluster instance is received from the management element, wherein the method further comprises:

transmitting, to the OSS, a request for generating the container cluster instance, and

receiving, from the OSS, an agreement response comprising the CCD template or an identification of the CCD template.

3 . The method of claim 1 , wherein the container cluster instance is generated by:

requesting for allocating at least one of computing resources, storage resource or network resources for the at least one master node and at least one work node based on the CCD template.

4 . The method of claim 1 , further comprising:

receiving a request of CCD template on-boarding from at least one of the management element, an operation support system (OSS), or a third party,

receiving the CCD template from at least one of the management element, the OSS or the third party, and

transmitting an identification of the received CCD template to at least one of the management element, the OSS or the third party.

5 . The method of claim 1 , wherein the CCD template further comprises at least one of master node attribute information, work node attribute information, network attribute information or image information of the container cluster instance,

wherein the master node attribute information comprises at least one of the number of the at least one master node or deployment flavor information of the at least one master node,

wherein the deployment flavor information of the at least one master node comprises at least one of configuration information, deployment information or resource information,

wherein the work node attribute information comprises at least one of the number of the at least one work node or deployment flavor information of the at least one work node,

wherein the deployment flavor information of the at least one work node comprises at least one of configuration information, deployment information or resource information, and

wherein the network attribute information comprises at least one of network ports, internet protocol addresses of the at least one master node and the at least one work node, or network information of connections among the at least one master node and the at least one work node.

6 . A method for use in a management element, the method comprising:

receiving, from a container cluster management (CCM) element, a container cluster instance for use in a life cycle management operation of at least one virtual network function,

wherein the container cluster instance is generated based on a container cluster descriptor (CCD) template and comprises at least one master node deployed as at least one container infrastructure service manager (CISM) and at least one work node deployed as at least one container infrastructure service instance (CISI),

wherein the CCD template comprises cluster attribute information, and

wherein the cluster attribute information comprises at least one of a cluster name, a version or resource information, for efficient management of cluster resources for the life cycle management operation.

7 . The method of claim 6 , further comprising:

transmitting, to the CCM element, a cluster generation request of generating the container cluster instance,

wherein the cluster generation request comprises an identification of the CCD template,

wherein the method further comprises:

transmitting, to the CCM element, a request for a management of the container cluster instance.

8 . The method of claim 6 , further comprising:

allocating at least one of computing resources, storage resource or network resources for the at least one master node and at least one work node based on the CCD template.

9 . The method of claim 6 , further comprising:

transmitting, to the CCM element, a request of CCD template on-boarding,

transmitting, to the CCM element, the CCD template, and

receiving, from the CCM element, an identification of the transmitted CCD template.

10 . The method of claim 6 , wherein the CCD template further comprises at least one of master node attribute information, work node attribute information, network attribute information or image information of the container cluster instance,

wherein the master node attribute information comprises at least one of the number of the at least one master node or deployment flavor information of the at least one master node,

wherein the deployment flavor information of the at least one master node comprises at least one of configuration information, deployment information or resource information,

wherein the work node attribute information comprises at least one of the number of the at least one work node or deployment flavor information of the at least one work node,

wherein the deployment flavor information of the at least one work node comprises at least one of configuration information, deployment information or resource information, and

wherein the network attribute information comprises at least one of network ports, internet protocol addresses of the at least one master node and the at least one work node, or network information of connections among the at least one master node and the at least one work node.
