具体实施方式
以下结合附图对本公开的具体实施方式进行详细的说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
参见图2，为本公开实施例提供的一种基于容器的虚拟资源管理系统的架构示意图。
如图所示，基于容器的虚拟资源管理系统200(图中仅画出了与本公开实施例相关的部分)由网络功能虚拟化编排器(NFVO)、虚拟化网络功能管理器(VNFM)、容器管理器(container controller)以及虚拟化基础设施管理器(VIM)共同组成，提供基于容器的NFV的整体管理和编排，向上接入业务/运维支撑系统(Operation Support System/Business Support System，OSS/BSS)。
NFVO用以协调VNF生命周期的管理(需要得到VNFM的支持)，协调网络功能虚拟化基础设施(Network Functions Virtualization Infrastructure，NFVI)各类资源的管理(需要得到VIM的支持)，并根据虚拟资源池中虚拟资源的使用情况为VNF协调分配虚拟资源以及授权，以使各个VNF以及虚拟资源在合理的编排下，确保各类资源与连接的优化配置。
NFVM用以管理VNF和基于容器的VNF的生命周期，比如上线、下线、进行状态监控等，NFVM根据NFVO授权给所请求创建的VNF的虚拟资源的指示信息通过与VIM进行信息交互请求创建该VNF所需的VM，并且NFVM可根据NFVO发起的创建VFN请求确定所请求创建的VNF为创建相关技术中的VNF还是基于容器的VNF，进而通过与容器管理器进行信息交互请求创建该VNF所需的容器。
容器管理器部署在VIM之上，用以通过与VNFM进行信息交互将VIM根据NFVO授权的虚拟资源的指示信息创建的VM作为节点纳管，为申请创 建的VNF创建所需的容器，其中，节点为虚拟资源用于在容器管理器中部署容器，容器用于承载VNF。
VIM用以管理NFVI以及控制VNF的虚拟资源分配，比如虚拟计算，虚拟存储以及虚拟网络等。VIM可通过与VNFM进行信息交互为申请创建该VNF所需的VM。
基于图2所示的系统架构，本公开实施例提供一种基于容器的虚拟资源管理方法，该方法用于实现基于容器的VNF的创建。
如图3所示为本公开实施例提供的基于容器的虚拟资源管理的消息交互示意图。
如图所示，该流程包括：
S301：NFVO向VNFM发送创建VNF请求消息。
其中，创建VNF请求消息中携带有创建该VNF所需的虚拟资源的描述信息，虚拟资源的描述信息包括创建该VNF所需的VM的数量信息，每个VM的大小信息以及每个VM所包括的授权给该容器管理器的虚拟CPU的标识信息和数量信息、授权给该容器管理器的虚拟内存的标识信息和大小信息等。
S302：VNFM接收创建VNF请求消息，并与NFVO进行消息交互获得NFVO授权给所请求创建的VNF所需的虚拟资源的指示信息。
具体地，VNFM接收到创建VNF请求消息后根据携带的创建该VNF所需的虚拟资源的描述信息确定NFVO所请求创建的VNF为相关技术中的VNF还是基于容器的VNF以及确定创建该VNF所需的虚拟资源并向NFVO返回响应消息；NFVO在接收到响应消息后根据虚拟资源池中虚拟资源的使用情况对所请求创建的VNF所需的虚拟资源进行授权，并将授权给所请求创建的VNF的虚拟资源的指示信息发送给VNFM，从而VNFM获得创建该VNF所需的虚拟资源的指示信息，完成所请求创建的VNF所需虚拟资源的申请和授权。
其中，虚拟资源由VIM所创建，用于为VNF提供基础实施服务，可以是虚拟CPU、虚拟内存等；虚拟资源的指示信息用于具体描述NFVO授权给 该容器管理器的虚拟资源，该虚拟资源的指示信息包括VM的数量信息，每个VM的大小信息以及每个VM所包括的授权给该容器管理器的虚拟CPU的标识信息和数量信息、授权给该容器管理器的虚拟内存的标识信息和大小信息等。
S303：VNFM获得NFVO授权给所请求创建的VNF的虚拟资源的指示信息后，向VIM发送创建虚拟机VM请求消息。
其中，该创建VM请求消息中携带有虚拟资源的指示信息。
S304：VIM接收创建VM请求消息，并根据携带的虚拟资源的指示信息创建VM，并向VNFM发送VM创建确认消息。
上述VM创建确认消息中携带有创建的一个或多个VM的标识以及创建的一个或多个VM的配置信息，比如VIM根据虚拟资源的指示信息为所请求创建的VNF创建VM1、VM2后，VIM将VM1、VM2的标识以及VM1、VM2分别可配置容器的数量等配置信息携带在VM创建确认消息中发送给VNFM。
S305：VNFM接收VM创建确认消息，向容器管理器发送虚拟资源分配请求消息。
其中，虚拟资源分配请求消息中携带有一个或多个VM的标识以及一个或多个VM的配置信息。
S306：容器管理器接收虚拟资源分配请求消息，并将虚拟资源分配请求消息中携带的一个或多个VM的标识对应的一个或多个VM作为配置容器的节点进行纳管。
S307：容器管理器将一个或多个VM作为节点纳管后，向VNFM发送虚拟资源分配确认消息。
其中，虚拟资源分配确认消息携带有用于描述VM与节点之间对应关系信息，一个VM对应一个节点，该对应关系信息包括VM的指示信息以及节点的指示信息。比如，VIM为所请求创建的VNF创建了VM1、VM2，容器管理器将VM1、VM2分别作为节点1、节点2进行纳管，则VM与节点之间对应关系为VM1对应节点1、VM2对应节点2。
S308：VNFM接收到虚拟资源分配确认消息后，向容器管理器发送创建 容器请求消息。
S309：容器管理器接收创建容器请求消息，基于所纳管的节点为所请求创建的VNF创建容器。
具体地，容器管理器接收到创建容器请求消息后，根据一个或多个VM的配置信息在S306中所纳管的节点上为所请求创建的VNF创建容器。
S310：容器管理器完成容器创建后，向VNFM发送容器创建确认消息。
其中，容器创建确认消息中携带有用于描述节点与容器之间对应关系信息，该对应关系信息包括节点的指示信息以及每个节点上创建的容器的数量信息。比如，容器管理器为所请求创建的VNF在节点1上创建了2个容器，在节点2上创建了1个容器，则节点与容器之间对应关系为节点1配置有2个容器，节点2配置有1个容器。
S311：VNFM接收到容器创建确认消息后，向NFVO发送VNF创建确认消息。
S312：VNFM建立VM与容器之间的对应关系。
在VNF创建完成后，VNFM建立并维护VM与容器之间的对应关系。具体地，容器管理器将VIM创建的VM作为节点进行纳管，并在所纳管的节点上创建一个或多个容器，即VIM不需要了解所创建的VM的用途，故VNFM需根据VM与节点之间的对应关系信息以及节点与容器之间的对应关系信息建立VM与容器之间的对应关系。
具体地，VNFM建立并维护VM与容器之间的对应关系，可用于后期运维和动态调整。比如，后期VM出现故障或需要迁移时，VNFM可根据VM与容器之间的对应关系，直接确定受影响的容器，并将这些受影响的容器进行相应的迁移和重建；在故障根因分析中，底层故障往往会引起上层故障，当同时，收到VM、容器、应用的故障时，VNFM可根据VM与容器之间的对应关系将三者的故障进行关联，从而分析故障根因，进行故障恢复。
在上述实施例中，VNFM将所请求创建的VNF的软件即服务(Software-as-a-Service，SaaS)的应用拆解为VM的基础设施即服务(Infrastructure-as-a-Service，IaaS)需求进行部署(S303～S304)；然后将IaaS的虚拟资源分配到平台即服务(Platform-as-a-Service，PaaS)的管理平台(容 器管理器)进行纳管(S305～S306)；从而能将VNF SaaS的应用拆解为PaaS中容器形态的微服务进行部署(S308～S309)，进而实现了基于容器的VNF的部署，其中，容器部署在VNFM分配到容器管理器中的VM(即节点)上。
本公开的上述实施例中，首先VNFM接收NFVO发送的创建VNF请求消息，获得NFVO授权给所创建的VNF的虚拟资源的指示信息；VNFM根据虚拟资源的指示信息通过与VIM消息交互得到创建所述VNF所需的VM的标识；VNFM指示容器管理器将VM的标识对应的VM作为容器的节点，并指示该容器管理器在节点上为请求创建的VNF创建容器；VNFM在确认NFV创建完成后，向NFVO发送VNF创建确认消息；上述实施例中，在NFV架构中部署容器管理器，通过VNFM与NFVO、VIM以及容器管理器间的消息交互，实现基于容器的VNF的创建。
基于相同的技术构思，本公开实施例还提供了一种虚拟化网络功能管理器VNFM，该VNFM可实现前述实施例中图3所执行的流程。
