The application environment of the container application includes a production environment, a test environment, a development environment, and the like. The production environment means that the container application is successfully established and then is connected with an external environment or is accessed by an external user; the test environment means that the container application is used for testing after being successfully created; the development environment means that the container application is successfully created and used for development. The area of the container application refers to a machine room location where the container application is created, and consists of two parts: "area" + "safe area". Wherein a "safe area" is a sub-area under a "area". It is understood that the container application is created in a machine room of "xxx safe area" under "xx area". However, determining in which specific machine room the container application is created needs to be determined according to the application environment of the container application and the area of the container application, and it can be understood that the container application is created in the machine room corresponding to the area of the container application in a certain application environment. It can be understood that the machine rooms corresponding to different application environments in the same area are different. The number of container instances for a container application refers to the number of containers for that container application, and there is no upper limit to the number of containers for a container application. Wherein, the number of container instances can be determined according to the access amount of the container application. The container instance mirror information includes a mirror version, a mirror type, and a mirror name.

In some embodiments, the information of the container application further includes a beneficiary resource pool, which refers to a subsidiary/department that creates the container application, determines the IP network segment allocated by the created container and the host resources of the container, and different resource pools, which use different IP network segments and host resources. If the information of the container application further comprises the beneficiary resource pool, the beneficiary resource pool together with the application environment of the container application, the area of the container application determines the IP network segment allocated by the created container instance and the host resources of the container instance.

The information of the load balancing application includes a type of the load balancing application, and port information of a Virtual Server (VS) of the load balancing application, where the type of the load balancing application is F5. The port information of the virtual server of the load balancing application may have one or more ports, where one port corresponds to one VS and a plurality of ports correspond to a plurality of VS. The port of the virtual server refers to an access port supported by the F5 load balancing application, that is, a port accessed in http mode, such as 80, 443, etc.

And S102, if the setting completion instruction is received, creating a container instance of the container application according to the set information of the container application.

The setting completion instruction is triggered by a user clicking a button for submitting and the like, the information of the container application and the information of the load balancing application are set, and the setting completion instruction triggered by the user is received, so that the container application, the load balancing application and the incidence relation between the container application and the load balancing application can be automatically established.

In one embodiment, step S102 includes: determining a container instance IP of the container application according to the application environment of the container application, the area of the container application and the number of container instances of the container application in the set information of the container application; creating a container instance according to the container application mirror image information, the application environment of the container application, the area of the container application and the number of the container instances of the container application in the set information of the container application, and setting the determined IP of the container instance as the IP of the created container instance.

The location where the container application is created, i.e., in which specific machine room the container application is created, may be determined according to the application environment of the container application and the area of the container application. Such as creating the container application in a computer room where SF (a smaller area identifier under the treasure letter) sub-area under the treasure letter (place name) area under the test environment is located. Acquiring an IP address pool which is pre-allocated at a corresponding position (below the machine room) in a database and is used for creating a container instance; and acquiring the idle IPs with the same number as the container instances of the container application from the IP address pool, and determining the idle IPs as the IPs of the container instances of the container application.

After the IP of the container instance for the container application is allocated, the container instance is then created. Specifically, the step of creating a container instance according to the container application mirror image information, the application environment of the container application, the area of the container application, and the number of container instances of the container application in the set information of the container application, and setting the determined IP of the container instance as the IP of the created container instance includes: determining a mirror image warehouse for storing mirror image information of the container application according to the application environment of the container application and the area of the container application, and extracting a specific mirror image required for creating a container instance from the determined mirror image warehouse according to the mirror image type, the mirror image version and the mirror image name of the mirror image information of the container application; determining resources required to be occupied for creating the container instance according to the container mirror image type, the mirror image version and the mirror image name, and determining a host for creating the container instance according to the application environment of the container application, the area of the container application and the resources required to be occupied for creating the container instance; and creating a container instance of the container application on the determined host according to the determined specific mirror image, and binding the created container instance with the determined container instance IP to set the determined container instance IP as the IP of the created container instance.

In the above process of creating the container instance, the determining of the specific mirror image and the determining of the execution sequence of the host that creates the container instance are not strictly limited, and in other embodiments, the host that creates the container instance may be determined first, and then the specific mirror image may be determined.

The location of creating the container application, that is, in which specific machine room the container application is created, can be determined according to the application environment of the container application and the area of the container application. It should be noted that in each application environment, a mirror repository for storing mirror resources is corresponding to each region. All mirror resources needed by the area in the application environment are saved in the mirror repository. Acquiring an IP address pool of a host machine which is pre-allocated at a corresponding position (below the machine room) in a database and is used for creating a container instance; and determining the host machine for creating the container instance from the IP address pool of the host machine according to the resources occupied by creating the container instance. Creating a container instance requires occupying certain resources on the host, and therefore, it is necessary to determine the resources occupied by creating the container instance first to determine whether the host has enough resources to create the container instance. The resources that need to be occupied for creating the container instance include a CPU (such as the number of CPU cores), a memory, monitoring resources, and the like.

The method comprises the following steps of establishing a container instance of the container application on the determined host according to the determined specific mirror image, and binding the established container instance with the determined container instance IP, wherein the steps comprise: sending the determined specific mirror image to the determined host computer for creating the container instance through the container arrangement tool so as to create the container instance; if the creation is completed, the container instance is connected through an operation and maintenance tool such as an allowed tool, and the created container instance is bound with the determined container instance IP. After the container instance is successfully created, returning a message of successful creation; if the container instance fails to be created, the reason of the creation failure is returned.

and pushing the monitoring enabling identification in the monitoring enabling information corresponding to the container instance to the determined host machine so as to collect the running data information of the container instance according to the monitoring process of the host machine. Wherein, the monitoring process is installed on all the hosts by default and is in an enabled state. And pushing the monitoring enabling identification to the determined host machine, and monitoring the container instance through a monitoring process installed on the host machine.

S103, determining the virtual IP of the virtual server and the F5 equipment for creating the load balancing application according to the set information of the container application.

The Virtual IP is Virtual IP, which can be abbreviated as VIP. The VIP is also an IP address, which is a destination address to receive external (internet users or other users) access requests, and a source IP address to which internal (servers providing application services) send messages to the outside. Typically, one container application corresponds to one VIP, and one VIP may correspond to multiple VS (virtual servers). Such as 10.1.2.4 for VIP. If there are two ports of the virtual server, 80 and 443 are provided. Then 10.1.2.4:80 corresponds to one VS and 10.1.2.4:443 corresponds to another VS. I.e., a VS includes a VIP and a port information. It will also be appreciated that a virtual server may be accessed via the VIP and a port.

In one embodiment, step S103 includes: determining a virtual IP address pool according to the application environment of the container application and the area of the container application in the set information of the container application; determining an IP address from a virtual IP address pool, and setting the determined IP address as the virtual IP of the virtual server; determining an F5 device group according to the application environment of the container application and the area of the container application; one F5 device is determined from the group of F5 devices as the F5 device that created the load balancing application.

And searching a virtual IP address pool allocated to the corresponding computer room from the database according to the application environment of the container application and the area of the container application, determining an IP address from the virtual IP address pool, and taking the IP address as the VIP of the virtual server. And searching an F5 device group allocated to the corresponding computer room from the database according to the application environment of the container application and the area of the container application, and determining one device from the F5 device group under the corresponding computer room as an F5 device for creating the load balancing application. It should be noted that the load balancing application F5 is hard load balancing, i.e., a load balancing application needs to be created on a specific hardware device F5. Since the F5 device needs to be purchased, there is typically only one F5 device under a room for cost considerations, and then this device is treated as the F5 device that creates the load balancing application. It should be noted that the order of determining the F5 devices for creating the load balancing application and determining the VIP is not limited, and the F5 devices may be determined first, and then the VIP may be determined.

And S104, associating the created container instance with the virtual server to obtain an association relation, and encapsulating the association relation, the information of the created container instance, the port information, the virtual IP and preset load balancing parameter information into an object.

Wherein, the created information of the container instance mainly refers to the IP of the container instance. In some embodiments, the information for the created container instance also includes a container instance port. A container instance port refers to a port, such as an 8080 port, where the container instance (server) provides application services. Note that the port here refers to a different port from the port in the port information of the virtual server. If the set information of the container application further includes an application administrator, the application administrator needs to be packaged into an object.

In one embodiment, as shown in FIG. 3, step S104 includes the following steps S201-S204.

S201, taking each container instance as a correlation server, and taking all the created container instances as a correlation server cluster.

S202, generating the name of the associated server cluster, the name of the virtual server and the name of the container application according to a preset name generation rule.

The preset name generation rule is preset. The name generation rules corresponding to different names are different. If the name generation rule of the association server cluster (pool) is: pool-container application identification _ application environment number of container application _ serial number generated in order of pool configuration, and the like. The container application identifier is used for representing the calling logic of the container application, and is mainly used for information identification inside an enterprise. The container application identifier may be set in a preset setting interface. For example, the name of pool is: pool _ ABC _ stg10111, where ABC is a container application identifier, stg1 is an application environment number identifier of the container application, and 0111 is a serial number generated in the configured order. If the name generation rule of the VS is: VS _ container application identifier _ port number _ application environment number of container application _ serial number generated in the order of VS configuration, and the like. If the name of VS is: pool _ ABC _80_ stg 10123. The preset name generation rule may also be another rule as long as the generated name can be distinguished. If the name generation rule of the container application is: container application identification _ container application name identification _ container application image belongs to type. The container application name identifier can be set in a preset setting interface. Such as the container application name: ABC _ tag1_ web. Where ABC is the container application identifier, tag1 is the container application name identifier, and the web is the type to which the container instance image belongs. It is noted that the type of container application image is different from the type of container application image.

S203, associating each associated server with a server in the server cluster, and associating the associated server cluster with the server cluster of the virtual server to obtain an association relation.

One Virtual Server (VS) corresponds to one server cluster (pool). A server cluster may be understood as a server cluster corresponding to a load balancing application, and there are multiple servers (pool members) in a server cluster (pool), and the multiple servers are used for really responding to an external access request. After receiving the external access request, the VS allocates the external access request to one server in the server cluster according to a load balancing algorithm, and the allocated server responds to the external access request. And associating the virtual server with the associated server cluster, such as setting a server cluster (pool) of the virtual server as the associated server cluster. Associating the server in the server cluster of the virtual server with a plurality of associated servers, for example, setting the server members (poolmembers) of the server cluster of the virtual server as the plurality of associated servers, and setting the number of the server members in the server cluster as the number of the associated servers.

S204, packaging the generated multiple names, the incidence relation, the created container instance information, the port information, the virtual IP and the preset load balancing parameter information into an object.

The port information is port information of the virtual server, such as 80, 443, etc. The load balancing parameter information includes parameters such as a monitoring protocol (e.g., TCP, etc.), a load balancing algorithm (e.g., round robin, minimum connection mode, etc.), Http profile (e.g., Http), a health check mode (e.g., mode for selecting a load balancing F5 application to monitor a container application, e.g., F5monweb), SNAT mode (SNAT mode for selecting VIP function address translation of a virtual server, including SNAT/DANT universal mode, SNAT mode, etc.), setting of cookie mode, SNAT Pool (IP address Pool for selecting SNAT mode, i.e., IP address range after address translation of an access request source address/destination address) and the like. Obtaining preset load balancing parameter information, wherein the obtaining of the preset load balancing parameter information comprises: presetting a default value for each load balancing parameter according to the current operation requirement of an enterprise; and taking the set default value of each load balancing parameter as preset load balancing parameter information. The default value of each load balancing parameter is set according to the current operation requirement of the enterprise, and can also be understood as the default value is most matched with the current requirement of the enterprise.

In one embodiment, step S204 includes: converting the generated multiple names, the incidence relation, the created container instance information, the port information, the virtual IP and the preset load balancing parameter information into data in a preset format; and encapsulating the data converted into the preset format into an object.

The preset format is a data format matched with the load balancing application creation interface.

And S105, calling a creation interface of the load balancing application according to the packaged object to create a virtual server of the load balancing application on the determined F5 device, and generating a configuration file of the virtual server.

The creation interface of the load balancing application is a function, and parameters in the function comprise encapsulated objects. By the function, an F5 load balancing application (virtual server) can be automatically created on the F5 device according to the related information of the packaged object, and a configuration file of the F5 load balancing application (virtual server) is generated in the creating process. It is understood that, the configuration file of the virtual server includes related information of the F5 device (including IP, device number, etc. of the F5 device), related information of the virtual server (including VS name, VIP, port information, operating state information of the VS, etc.), related information of the Pool related to the VS (including Pool name, number of Pool members, operating state information of the Pool, etc.), related information of the Pool members (IP of each Pool member (i.e., IP of a container instance), port of a container instance, operating state information of each Pool member, etc.), related information of the container application (including container application name, container application manager, etc.), related information of the load balancing parameters (including load balancing related parameters such as Http profile, cookie mode, SNAT mode, load balancing algorithm, listening protocol, SNAT Pool, etc.), etc.

And S106, if a message that the virtual server is successfully created is received, generating an access domain name according to a preset domain name generation rule, and binding the access domain name with the virtual IP of the virtual server so as to access the virtual server through the access domain name.

After the F5 load balancing application is created, the load balancing service of the VS is automatically started. After the start, the VS running state, the pool running state and the pool member running state are changed from the stop state to the start state.

Since the F5 load balancing application is created on the F5 device, the relevant information is returned regardless of success or failure of creation. If a returned message that the load balancing F5 application is successfully created is received, generating an access domain name; and if a message of returning failure is received, positioning the problem according to the failure reason. And when the access domain name is generated, the access domain name is generated according to a preset domain name generation rule. And binding the access domain name with the virtual IP after generating the access domain name so as to access the virtual server through the access domain name.

The F5 load balancing application is created at the same time when the container application is created, and the created container application and the created F5 load balancing application are automatically associated, so that the container creation application and the F5 load balancing application do not need to be created separately and manually associated, and the creation speed is increased. The F5 load balancing application is created while the container application is created, and the created container application and the created F5 load balancing application are automatically associated, so that the whole process is automatically completed, the creating speed and efficiency are further increased, and the time cost and the labor cost are saved.
