Wherein, acC c-th of element is represented, if there are micro services in ∏ s for c class micro services, ac=1, otherwise ac= 0；bdD the d+1 element is represented, if there are micro services in ∏ s belongs to d-th of CIM subject area, bd=1, otherwise bd=0.
b1,b2…bdAccording to CIM definition, including one-level, two grades of subject areas, a main subject heading domain can include multiple two grades Subject area.
In above-mentioned S103, because a container can only load a micro services, but (such as operation process is tracked a micro services Service) it can be loaded into several virtual containers, form the example of multiple micro services.In the present embodiment, micro services base Realized in Spring Cloud frameworks, the packing and issue of micro services are completed with Spring Boot.Realized based on Docker technologies Virtual container, Docker is the Lightweight Container technology based on Linux processes, and the image file of micro services is loaded into process In, the program only in mirror image can access data in container, and the isolation of information flow is realized by the isolation of Docker containers.Institute It is as follows so that the micro services in micro services set are loaded into detailed process in virtual container by micro services management plane：
First the virtual container V in electric network information physical system is represented with following formula：
Wherein, the remaining assignable virtual container of V ' expressions, VmThe virtual container that micro services management plane is used is represented,Represent respectivelyThe virtual container set used；
In the present embodiment 3, Docker containers, which are operated in, to be mounted with Linux X86 servers, based on Spring frameworks With Docker Swarm management assemblies, develop micro services management plane, such as it is different using Zuul reverse proxys assembly management The service logics such as customization authority, the proof of identity of service caller.Information exchange is carried out between each virtual container, and is defined
Between virtual container be not present repeat, i.e., virtual container directly can not switch between services, Must through the process for recovery and reloading micro services in micro services management plane；Formalization representation is：
In G (V, →),Have：
And
Wherein, T represents state set, and t represents state；A represents the set of actions of electric network information physical system, and a represents dynamic Make；V represents virtual container, vSRepresentIn any virtual container；(t a) represents to hold under t step Row a reaches the process of next state；The virtual container that addr (t, s) expressions micro services s is used under t, addr (step (t, A), s) represent the virtual container that micro services s is used when t performs a to next state.
In above-mentioned S103, the isolation to micro services is realized by CIM subject areas, detailed process is as follows：
First determine that virtual container meets following constraints simultaneously：
1)Between the virtual container repeated is not present, formalization representation is：
Work as vx∈addr(t,s)∧vyDuring ∈ addr (t, s), vx=vy
Wherein, vx,vyRepresentIn any virtual container；
2) assignable virtual container is in init state, and assignable virtual container does not include the micro services left And the data of micro services, formalization representation is：
Wherein, domain (t, v, s) represents that v is loaded with after s in electric network information physical system, the corresponding CIM themes under t Domain；Domain (t, v, s)=0 represents to initialize virtual container, and all v in V ' are satisfied by domain (t, v, s) =0；
3)The corresponding CIM subject area of each virtual container used, andIn implementation procedure,CIM subject areas Keep constant, formalization representation is：
Wherein, tx,tyRepresent the free position in T, step (tx, a) represent in txLower execution a reaches next state Process, step (ty, a) represent in tyLower execution a reaches the process of next state；
Then, the above-mentioned constraints met according to virtual container makes micro services mutually call, to realize to micro services Isolation.In the intelligently operation of fortune inspection managing and control system, micro services are loaded into Docker containers and run, and the file system of container All it is the catalogue being mounted in true linux system, Docker containers can not pass through catalogue and go to access the data of other containers, I.e. all containers are all isolated in file system.It therefore, it can, by the means such as catalogue carry and access rights configuration, realize container Isolation and micro services unloading when data filing cleaning, so as to realize isolation of the information flow in virtual container rank.
