摘　　要：当前军事指挥信息系统一般采用基于预置规则的控制策略,在运行过程中很难根据环境变化快速进行动态调整;商用的容器云编排管理系统存在调度算法单一、弹性伸缩策略简单不宜扩展等问题。为此,提出了一种基于作战任务优先级的容器云弹性伸缩系统方案。对任务和资源进行建模描述,提出了一种基于作战任务优先级的资源调度算法和自适应弹性伸缩策略,并对该系统进行了设计与实现。最后,通过构建演示环境进行系统测试,验证了该策略与算法的有效性。The control strategy based on preset rules is usually adopted in the traditional material com⁃mand information systems,and it's difficult to adjust dynamically and rapidly according to the changes of environment during operation.In the commercial container cloud management systems,problems exist such as single scheduling algorithm,and simple elastic scaling strategy,etc..Aimed to these problems,a scheme of container cloud elastic scaling system based on mission priorities is proposed.The mission and the resource are modeled and described.A resource scheduling algorithm and an adaptive elastic scaling strategy based on mission priorities are presented,and the system is designed and implemented.Finally,a demon environment is constructed and the system testing is performed.The effectiveness of the algorithm and the strategy is verified.
