Description

  The present disclosure relates to a computer system, a parameter setting device, a method, and a program, and more particularly, to a computer system that operates a service on a server, and a parameter setting device, a method, and a program used in such a computer system.

  Containers used in OS (Operating System) level virtualization technology are known. A container is an application that runs in an isolated user space. The software that implements the container is called the container runtime. As container runtimes, for example, Docker provided by Docker, rkt provided by CoreOS, and the like are known.

  In addition to running applications in an isolated user space, the container runtime can attach a virtual file system or virtual network to the container, making the container look like a single machine. A file in which a virtual file system used by a container and setting information (for example, information for setting a virtual network) necessary for executing the container are collectively called a container image. As a related technique, Patent Literature 1 discloses an apparatus that distributes a container image.

  As another related technique, Patent Document 2 discloses a system parameter setting support system. The system parameter setting support system described in Patent Document 2 includes a test device and a test target system. The test target system has a plurality of parameters whose settings can be changed. The test device sends a request to the system under test to perform the test. The test includes, for example, a performance test that verifies the operation and performance of the system while applying various loads to the test target system and changing the settings of various parameters. Tuning is performed while changing a plurality of parameters during a performance test, and parameters for actual operation are determined.

  As the application execution platform of the client-server model shifts to PaaS (Platform as a Service), the application architecture is also being changed to a microservice architecture suitable for operation on the PaaS platform. This microservice architecture is based on the premise that the system is differentiated in units of services, and the differentiated functions are operated on a platform provided using a container technology such as a Linux (registered trademark) container.

  Open Shift has been proposed as an orchestration tool for managing containers. By specifying the server on which the container is to be operated in advance in the orchestration tool, the container can be freely started on the server and the service can be operated on the container.

  In the related art, the orchestration tool that performs container management includes a master node, a node managed by the master node, and a repository that manages an image to be deployed on the node. A worker who develops a system conforming to the microservices architecture uses a development environment, divides the system into elements, creates container images in units of services, and registers them in a repository. The scheduler in the master node deploys the container on the node based on the conditions defined for itself, and operates the service on the container.

  Here, the entity of the node is a server, and the hardware configuration and the network configuration may be different for each server. In the related art, a container orchestration tool deploys a container to a node in consideration of the load status and fault tolerance of the node itself, and runs an application on the node. However, at the time of actually operating an application, a difference occurs due to a difference in a hardware configuration or a network configuration, and at present, an optimal solution for operating the application is not considered.

  In Patent Literature 2, parameters of the test target device can be adjusted, so that desired processing performance can be realized. However, when the application is operated by expanding the container on the node, it is necessary to recreate an image including the setting information in order to change the setting. Since the nodes on which the images are deployed are allocated according to the judgment of the master node, it is difficult to make settings for the application to complete the processing in the shortest time according to the nodes to be deployed.

  In view of the above, the present disclosure provides a computer system, a parameter setting device, a method, and a program that can reflect a setting change in a container operating on a server without changing an image that is a source of the container. With the goal.

  In order to achieve the above object, the present disclosure provides a management device that is generated from a container image, operates on a server, and holds address information for accessing a container including an application unit and a framework unit; A parameter setting device for accessing the container based on the address information and transmitting setting information of parameters of the framework unit to the container, wherein the framework unit includes a setting reflecting unit, and the setting reflecting unit includes: A computer system for changing a parameter of the framework unit according to setting information transmitted from the parameter setting device is provided.

  Prior to the description of the embodiments of the present disclosure, an overview of the present disclosure will be described. FIG. 1 illustrates a computer system according to the present disclosure. The computer system 10 has a management device 11 and a parameter setting device 12. The management device 11 holds address information generated from the container image and for accessing the container 30 operating on the server 20. The container 30 includes an application unit 31 and a framework unit 32.

  The parameter setting device 12 accesses the container 30 based on the address information held by the management device 11. The parameter setting device 12 transmits the setting information of the framework part 32 of the container 30 to the container 30. The framework unit 32 includes a setting reflecting unit 33. The setting reflecting unit 33 changes the parameters of the framework unit 32 according to the setting information transmitted from the parameter setting device 12.

  In the present disclosure, the parameter setting device 12 transmits setting information to the container 30 using the address information of the container 30 held by the management device 11. The framework unit 32 of the container 30 has a setting reflecting unit 33, and the setting reflecting unit 33 sets parameters in the framework unit 32 based on the setting information transmitted from the parameter setting device 12. By doing so, it is possible to change the parameters of the framework unit 32 without changing the container image from which the container is generated.

  Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. FIG. 2 illustrates a computer system according to the first embodiment of the present disclosure. The computer system 100 has a master node 101, a parameter setting device 102, and a node 103. The master node 101, the parameter setting device 102, and the node 103 are configured as, for example, a server computer. The functions of the master node 101, the parameter setting device 102, and the node 103 can be realized by the processor in the server computer operating according to the program read from the memory. These devices need not necessarily be configured as physically separate devices. In addition, each device may be configured using a plurality of physically separated devices.

In the present embodiment, the following environment is assumed.
(1) In accordance with the macro service architecture, system elements are differentiated for each service, and each service operates on a container.
(2) The operation of the container is executed using an orchestration tool. The orchestration tool defines information for specifying a server (node) on which the container operates and information for accessing a service operating on the container.
(3) The container is a client-server model Web server or application server having an architecture that can be separated into an application unit and a framework unit for service execution.

  The repository 104 holds a container image from which a container is generated. The repository 104 holds, for example, a container image 141 of the service A, a container image 142 of the service B, and a container image 142 of the service C.

  The master node 101 has a scheduler 111 and management information 112. The scheduler 111 determines a server that deploys the container image. The scheduler 111 acquires the container image 141 of the service A from the repository 104, for example, and expands the acquired container image 141 on the node 103. The management information 112 includes virtual address information (virtual address) 113 for each container, information (node information) 114 of the node on which the container operates, and a URL (uniform resource locator) (service URL) 115 provided by the service. . The master node 101 corresponds to the management device 11 in FIG.

  The node 103 is a server that operates the container 130 expanded by the scheduler 111. The container 130 provides a specific service. Each service includes an application unit 131 and a framework unit 132. The application unit 131 is an entity that provides a service. The framework unit 132 is a framework for operating an application. The node 103 corresponds to the server 20 in FIG. 1, and the container 130 corresponds to the container 30 in FIG. 1. The application unit 131 corresponds to the application unit 31 in FIG. 1, and the framework unit 132 corresponds to the framework unit 32 in FIG.

  The framework unit 132 includes setting information 133 and a setting reflecting function (setting reflecting unit) 134. The setting information 133 is setting information of a plurality of parameters that can be set in the framework unit 132. The setting reflection function 134 is provided as one function of the framework, receives a request in a specific URL format, and performs a parameter setting change operation. More specifically, the setting reflection function 134 receives a request including parameter setting information from the parameter setting device 102, and stores the setting information included in the received request in the setting information 133. For example, after storing the setting information, the setting reflecting function 134 restarts the framework unit 132 to operate the framework unit 132 with parameters according to the setting information newly stored in the setting information 133. The setting reflecting function 134 corresponds to the setting reflecting unit 33 in FIG.

  The parameter setting device 102 includes an access destination information acquisition unit (access destination information acquisition unit) 121 and a setting input unit (setting input unit) 122. The access destination information acquisition unit 121 acquires the virtual address 113 of the container 130 from the master node 101. The setting input unit 122 transmits the setting information stored in the setting information 133 of the framework unit 132 to the container 130. At this time, the setting input unit 122 generates a request in which the virtual address 113 acquired by the access destination information acquiring unit 121 and the setting information are combined, and transmits the setting information to the container 130. The setting input unit 122 receives setting information from a user, for example. The parameter setting device 102 corresponds to the parameter setting device 12 in FIG.

  Hereinafter, a method (parameter setting method) performed in the computer system 100 will be described. FIG. 3 shows an operation procedure when changing the parameters of the framework 132 of the container 130. For example, the user specifies a service or the like whose setting is to be changed, and inputs parameter setting information to the setting input unit 122 (step A1). The setting input unit 122 calls the access destination information acquisition unit 121, and the access destination information acquisition unit 121 acquires the virtual address 113 held on the master node 101 (Step A2).

The setting input unit 122 constructs a URL for parameter setting using the virtual address 113 obtained in step A2 (step A3). Further, the setting input unit 122 adds the parameter input by the user to the setting URL, and generates a setting URL including the parameter after the setting change (step A4). In step A4, the setting input unit 122 generates a request in the following URL format, for example.
http: // {virtual address} / setting? param = {parameter name} & data = {input data}

  The setting input unit 122 transmits the setting URL generated in step A4 to the container 130, and calls the setting reflecting function 134 of the framework unit 132 (step A5). The setting reflection function 134 stores the setting information of the parameters included in the setting URL in the setting information 133 (Step A6). In step A6, the setting reflection function 134 replaces the setting value of the parameter indicated by, for example, the “parameter name” included in the setting URL with the value of “input data” included in the setting URL. After storing the setting information, the setting reflecting function 134 restarts the framework 132 (step A7). After the restart, the framework unit 132 operates according to the setting information newly stored in the setting information 133.

  In the present embodiment, the framework 132 of the container 130 has a setting reflection function 134. The parameter setting device 102 acquires a virtual address 113 that is virtual address information of the container 130 from the master node 101, and transmits a request including the setting information to the container 130. In the present embodiment, setting information can be transmitted from outside the container 130 to the setting reflection function 134 in the container 130 by using a virtual address prepared for each container. By changing the setting information 133 in the framework unit 132 according to the setting information received by the setting reflecting function 134, the parameters of the framework unit 132 can be changed.

  For example, a node where a certain container image is arranged is not specified as one node, and a certain container image may be arranged at two different nodes. In that case, the parameters of the framework unit 132 in the container 130 generated from one container image are optimal at one node but not necessarily optimal at the other node. In the present embodiment, since the setting change in the framework unit 132 can be executed for each service, even if the original container image is not changed, the parameter can be changed according to the status of the node where the container 130 is located. Can be changed accordingly. Therefore, while using the same container image, each node can execute a service with parameters according to the status of each node.

  Subsequently, a second embodiment of the present disclosure will be described. FIG. 4 illustrates a computer system according to the second embodiment of the present disclosure. In the present embodiment, in addition to the access destination information acquisition unit 121 and the setting input unit 122, the parameter setting device 102a includes a parameter definition information storage unit 151, a parameter setting analysis unit 152, a setting injection unit 153, a setting storage unit 154, a measurement It has a result receiving unit 155, a deriving unit 156, and an application executing unit 157.

  This embodiment is different from the first embodiment in that the parameter setting device 102a adjusts the setting information of the parameters set in the framework unit 132. The master node 101 and the node 103 may be the same as those described in the first embodiment. In FIG. 4, the repository 104 (see FIG. 2) is not shown.

  The parameter definition information storage unit (parameter definition information storage unit) 151 stores parameter definition information (parameter definition information) of the framework unit 132. The parameter definition information storage unit 151 stores parameter definition information for parameters to be adjusted in parameter adjustment. FIG. 5 shows an example of the parameter definition information. The parameter definition information includes a set of a parameter name and input data. The parameter definition information is input, for example, by a user. In the parameter definition information, the data range and the like are defined by, for example, a regular expression.

  The parameter setting analysis unit (parameter setting analysis unit) 152 analyzes the parameter definition information stored in the parameter definition information storage unit 151, and calculates a parameter name and a parameter data range. The setting injecting unit (setting injecting means) 153 transmits the parameter name and the data range of the parameter calculated by the parameter setting analyzing unit 152 to the setting storing unit (setting storing means) 154. The setting storage unit 154 stores the parameter name and parameter data range transmitted from the setting injecting unit 153 as candidates for setting information to be set in the framework unit 132.

  The application execution unit (application execution unit) 157 transmits a request to a service provided by the container 130 and causes the application to execute. At this time, the application execution unit 157 accesses a service provided by the container 130 based on the service URL 115 held in the master node 101. When the application is executed, the application execution unit 157 measures the processing performance index of the container 130. The application execution unit 157 measures, for example, the execution processing time of the application as a processing performance index.

  The deriving unit (parameter deriving unit) 156 derives parameter setting information of the framework unit 132. Bayesian optimization is used to derive the setting information, for example. In deriving the setting information, the deriving unit 156 transmits the setting information within the data range stored in the setting storage unit 154 to the setting reflecting function of the framework unit 132 via the setting input unit 122. After transmitting the setting information, the derivation unit 156 calls the application execution unit 157 and causes the container 130 to execute the application.

  The measurement result receiving unit (measurement result receiving unit) 155 receives the processing performance index measured at the time of executing the application from the application executing unit 157. The measurement result receiving unit 155 notifies the derived processing performance index to the deriving unit 156. The deriving unit 156 derives the setting information having the best processing performance index, for example, the shortest execution processing time by performing Bayesian optimization, for example. The deriving unit 156 transmits the derived setting information to the setting reflecting function of the framework unit 132 via the setting input unit 122.

  Hereinafter, the operation procedure will be described. FIG. 6 shows an operation procedure when parameter definition information is input. The user sets a parameter definition in the parameter definition information storage unit 151 (Step B1). In step B1, the user sets, for example, a parameter name of a parameter that can affect the operation of the node 103, a range thereof, and the like.

  The parameter setting analysis unit 152 analyzes the input data (see FIG. 5) registered in the parameter definition information storage unit 151, and derives a settable input value (step B2). The setting injecting unit 153 stores the inputtable value derived in step B2 in the setting storage unit 154 (step B3). At this stage, preparation for parameter adjustment is completed.

  FIG. 7 shows an operation procedure at the time of parameter adjustment. After the container image is placed on the node 103, the user can instruct the parameter adjustment at an arbitrary timing. When the user instructs to adjust the parameters, the access destination information acquisition unit 121 acquires the management information 112 from the master node 101 (Step C1). In step C1, the access destination information acquisition unit 121 acquires the virtual address 113, the node information 114, and the service URL 115. The setting input unit 122 constructs a service access destination URL and a parameter setting URL by combining the management information acquired in step C1 (step C2).

  The deriving unit 156 performs Bayesian optimization using the set value and the inputtable value of the set value as arguments, and derives a set value to be investigated (step C3). The deriving unit 156 notifies the setting input unit 122 of the derived setting value. The setting input unit 122 transmits the setting value derived in Step C3 to the setting reflecting function 134 of the framework unit 132 using the setting URL constructed in Step C2 (Step C4). In step C4, the setting input unit 122 assigns the setting value derived in step C3 to the setting URL constructed in step C2, and transmits the setting URL to which the setting value has been assigned to the setting reflecting function 134. I do.

  The setting reflection function 134 stores the setting information of the parameters included in the setting URL in the setting information 133 (Step C5). After storing the setting information, the setting reflecting function 134 restarts the framework unit 132 (Step C6). After the restart, the framework unit 132 operates according to the setting information newly stored in the setting information 133. Steps C5 and C6 may be the same as steps A6 and A7 in FIG.

  After restarting the framework unit 132, the application execution unit 157 causes the container 130 to execute a service (application) (Step C7). In step C7, the application execution unit 157 causes the container 130 to execute the application using the access destination URL of the service constructed in step C2. The application execution unit 157 measures the processing performance index of the container 130 (node 103) (Step C8). In step C8, the application execution unit 157 measures, for example, the execution processing time of the application.

  The application execution unit 157 transmits the processing performance index measured in Step C8 to the measurement result receiving unit 155. The measurement result receiving unit 155 notifies the derived processing performance index to the deriving unit 156. The deriving unit 156 performs Bayesian optimization based on the set value and the processing performance index, and derives a new set value (Step C9).

  The deriving unit 156 determines whether the set value derived in step C9 is the same as the previous set value (step C10). If it is determined in step C10 that the derived setting value is different from the previous setting value, the process returns to step C4, and the new setting value is transmitted to the setting reflecting function 134 of the framework unit 132 via the setting input unit 122. Sent. The processing from step C4 to step C10 is repeatedly performed until it is determined in step C10 that the newly derived set value is the same as the previous set value.

  If the deriving unit 156 determines in step C10 that the set value is the same as the previous value, the derivation unit 156 ends the Bayesian optimization, and determines whether the parameter adjustment has been completed for all nodes to be subjected to parameter adjustment ( Step C11). If it is determined in step C11 that there is a node for which parameter adjustment remains, the process returns to step C3, and the derivation unit 156 performs Bayesian optimization on one node whose parameter adjustment has not been adjusted. If it is determined in step C11 that parameter adjustment has been completed for all nodes, the process ends.

  In the present embodiment, the deriving unit 156 derives setting information to be set in the framework unit 132 within the range of the parameter definition information. In the present embodiment, for example, the deriving unit 156 derives the setting information with the best processing performance index, so that the application completes the processing in the shortest time according to the status of the container or node where the service is deployed. Setting information can be automatically derived. Therefore, in the present embodiment, it is possible to improve the processing performance without changing the setting information after the system developer or the like investigates the service deployed on the node.

Non-transitory computer readable media includes various types of tangible storage media.
