It should be noted that the concept of "server" as referred to in this application can be extended to the case of a server cluster. According to the network deployment principle understood by those skilled in the art, the servers should be logically divided, and in physical space, the servers may be independent from each other but can be called through an interface, or may be integrated into one physical computer or a set of computer clusters. Those skilled in the art will appreciate this variation and should not be so limited as to restrict the implementation of the network deployment of the present application.
Referring to fig. 1, the hardware basis required for implementing the related art embodiments of the present application may be deployed according to the architecture shown in the figure. The server 80 is deployed at the cloud end, and serves as a business server, and is responsible for further connecting a related data server and other servers providing related support, so as to form a logically related server cluster to provide services for related terminal devices, such as a smart phone 81 and a personal computer 82 shown in the figure. Both the smart phone and the personal computer can access the internet through a known network access mode, and establish a data communication link with the cloud server 80 so as to run a terminal application program related to the service provided by the server.
The application program of the application program has various expression forms, and is essentially used for realizing various computer functions, so that the functions can be expressed by calling a third-party browser to access a webpage and executing a program module implanted in the webpage, or developed into various APPs suitable for being installed in terminal equipment, relevant function logics of the browser are embedded in the APPs, and the functions can be expressed by calling a remote webpage and executing various codes when the APPs run. Thus, in a sense, a browser is not a distinct concept from an application, and for an online service developed based on a web page, the application may have a built-in browser for accessing the web page, and the web page accessed through a separate browser may also implement the equivalent functions of the application. In the front of the technological surge of developing terminal applications based on page technology, those skilled in the art should understand this.
The web page and the application related to the present application are usually distributed to the server 80, and the terminal device may initiate access to the web page by calling the web page through a browser or by calling the web page by running the application with the equivalent function. The access to the web page is regarded as an access request to the target web page by the browser (or an application program, the same applies below), so that a request is sent to the server 80 to obtain the corresponding target web page, the server 80 pushes the HTML code of the target web page after responding to the request, the browser analyzes and executes the HTML code, and finally the content of the target web page is displayed in the graphical user interface of the terminal device 81, 82 where the browser is located.
Referring to fig. 2, the container cluster referred to in the present application is deployed through a kubernets container management system, which is often referred to as K8s for short, and the management of the docker container cluster through the K8s container management system is well known to those skilled in the art. The k8s container management system provides services of container deployment, planning and maintenance for the docker container cluster, can realize functions of balancing, automatic monitoring and restarting and the like, and has strong robustness. The k8s container management system constructed by the application adopts double master control nodes for management, for example, master1(90) master control node and master2(91) master control node in fig. 2, and a keepalive keep-alive detection mechanism is arranged between the two master control nodes, so that a docker container cluster composed of working nodes such as node1-1(92) and the like managed by the docker container cluster is ensured to have high availability, and the disaster tolerance capability of the container cluster is improved.
Referring to fig. 2 and fig. 3, a docker container cluster constructed in the present application is a container cluster composed of nodes 1-1(92) and other similar working nodes in fig. 2, where each working node has a plurality of pods deployed thereon, and the number of the deployed pods depends on the number of database types, each pod is used to manage a plurality of containers corresponding to one database type, 4 pods are deployed in the working node shown in fig. 3, pod1(100) deploys a container of mysql database, pod2(101) deploys a container of redis database, pod3(102) containers of mongodb database, and pod4(103) deploys a container of etcd database. Working nodes of the same database type are divided into master nodes and slave nodes, and the master nodes and the slave nodes can perform data synchronization regularly, for example, between node1-1(92) and node1-2(93) in fig. 3, when node1-1(92) goes down, node1-2(93) replaces node1-1(92) to be switched to the master working node for providing service to the outside, and after node1-2(93) switches the master working node, k8s creates the working node of the database type on healthy equipment to become a new slave working node, so as to ensure the number of the working nodes of the database type in the container cluster. It is emphasized that, as to the types of databases involved in the container cluster, depending on the container deployment requirements, only one type of database container may be involved, and any of a plurality of known database types may also be involved, without being limited by the database types listed above.
The person skilled in the art will know this: although the various methods of the present application are described based on the same concept so as to be common to each other, they may be independently performed unless otherwise specified. In the same way, for each embodiment disclosed in the present application, it is proposed based on the same inventive concept, and therefore, concepts of the same expression and concepts of which expressions are different but are appropriately changed only for convenience should be equally understood.
With the above disclosure of the relevant application and development environments associated with the embodiments of the present application in mind, reference is made to the following description for further understanding of various embodiments of the present application:
referring to fig. 2, fig. 3 and fig. 4, a container allocation method according to the present application is executed by an application program in a server hosting a resource scheduling library, and in an exemplary embodiment, the method includes the following steps:
step S11, monitoring the idle allowance of a class of container corresponding to at least one database type in the resource scheduling library, and when the idle allowance satisfies a preset condition, triggering a reselling event for complementing the idle allowance of the class of container to reach a rated quantity:
in one embodiment, before this step is started, the resource scheduling library needs to be initially created, so that the service server can implement a related method through the resource scheduling library, so that a developer can apply for a container to meet development requirements.
The business server triggers an initialization event, controls a certain main control node in the container cluster to create containers with rated quantity for each preset type of database by driving the main control node, and stores access channel certificates of all the containers in the resource scheduling library so as to send the corresponding access channel certificates to a requester applying for the containers.
The resource scheduling library is a database for storing access channel credentials, use states and container identity information of all containers in the container cluster, and is located in the service server, so that the service server provides millisecond feedback service for users and sends the access channel credentials of the corresponding containers to the user side.
The use state is used for representing the current use condition of the container and can be divided into an occupied state, an unoccupied state, a pause state and the like, so that the service server can judge whether the current container can be used for scheduling or not and determine the idle margin of each database type container.
The container identity information is suitable for the service server to distinguish all the containers stored in the resource scheduling library. Of course, the access channel credential can be theoretically regarded as a kind of container identity information, and thus, special container identity information can be set as needed.
The access channel credential generally includes a port designated for communication for a certain container, a network address of a corresponding working node in the container cluster, and corresponding verification information, and the specific generation process is as follows:
when a business server drives a certain main control node of a container cluster to create a corresponding new container, the business server submits a port which is pre-allocated and appointed for the new container to the main control node, so that the main control node generates an access channel certificate of the new container according to the port, the verification information of the container and the network address of the container cluster working node where the new container is located, and sends the access channel certificate to the business server, so that the business server stores the access channel certificate in a resource scheduling library.
The authentication information, which typically includes the user name and password of the database supported by the container, is provided according to the database type, for example, the redis and etcd databases do not necessarily require the authentication information, while mysql and mongodb do. These validation information may be custom provided by the requestor when requesting the container allocation, but is generally intended to be generated by the business server for submission to the container cluster for use.
In order to ensure that the idle allowance of the containers of the various types of databases in the resource scheduling library is enough to meet the container scheduling requirement of developers, the server monitors the current idle allowance of the containers storing the various types of databases in the resource scheduling library in real time, and if the idle allowance of the containers of a certain type of database is monitored to meet a preset condition, a bin filling event is triggered, and a certain main control node in a container cluster is driven to create the containers of the type of databases so as to fill the containers of the type of databases and enable the idle allowance to reach a rated quantity.
For example, the service server monitors the use states of containers of various types in the resource scheduling library, when the use state of a container of a certain database type is in an unoccupied state, the container is determined as an idle container by the service server, and the total amount of the idle containers corresponding to the certain database type is the idle margin of the container of the type.
The preset condition generally can be that a lowest idle number is preset as a trigger condition, and when a service server monitors that the idle allowance of a container of a certain database type is less than or equal to the lowest idle number, a bin filling event is triggered; those skilled in the art can flexibly design the preset condition as long as the service server triggering reselling event is satisfied, so that the idle margin of a container of a certain database type is compensated to the rated quantity.
Step S12, in response to the reselling event, the container cluster master node is driven to create the container type to obtain access channel credentials corresponding to the new containers, where the access channel credentials are used to reach access to the corresponding containers:
as described above, when the service server monitors that the idle allowance of a container of a certain database type meets the preset condition, a reselling event of the database type is triggered and responded, a certain main control node of the container cluster is driven to create the container of the database type, and access channel credentials of all new containers are acquired and stored in the resource scheduling library.
Referring to fig. 2, the service server drives a certain master node in the container cluster to create a container of a database type pointed by a reseeding event, for example, when the master node is master1, master1 queries whether there is a free computing resource in its master working node, such as node1-1, node2-1, etc., to create the container of the database type, and if there is a free computing resource in node1-1, it creates the container, otherwise, it is created by other working nodes, and finally completes creation of a new container.
Referring to fig. 2 and 3, when node1-1 working node is designated by master1, node1-1 working node will create a new container in the pod of the database type that is needed for the reselling event. When a node1-1 working node creates a new container, the access channel credential of the new container is created, so that the service server can obtain the access channel credential, store the access channel credential in the resource scheduling library, and supplement the idle margin of the container.
In one embodiment, if the reselling event contains a specified number of new containers, when the number of new containers created by the node1-1 working schedule reaches the specified number, so that the new containers obtained by the service server are added to the resource scheduling library and reach the rated number, that is, the reselling event is completed, the node1-1 working node will stop creating new containers.
In another embodiment, the service server triggers a reselling event for each new container that it needs, in which case, each reselling event drives the master node to create a new container, and after the new container is created, its access channel credential is returned to the service server, thereby completing the response to the reselling event. If the service server needs to supplement N new containers, N reselling events need to be triggered to drive the master node to implement N responses, so that N new containers are created.
The reselling event sent by the service server usually includes a port designated by the service server for a new container to be created, and if necessary, provides corresponding verification information, when the master node creates the new container, the master node may obtain a network address of a working node where the new container is located, configure the port provided by the service server as a communication port of the new container, and set the verification information for the new container using a database, and finally, form the access channel information with the network address where the working node is located, the port and the verification information (if any), and feed the access channel information back to the service server so as to complete a response to the reselling event. It will be appreciated that the user may access the new container through the network address and port in the access channel credential, and provide the authentication information if necessary to use the database functionality therein.
Step S13, the access channel credential is stored into the resource scheduling library to add a new container corresponding to the access channel credential, so that the idle allowance of the container is restored to the rated amount:
referring to fig. 3, each time a working node creates a new container in the pod of the corresponding type of database and creates an access channel credential of the new container, the service server acquires the access channel credential and stores the access channel credential in the resource scheduling repository, so as to complement the idle number of the containers of the database type to the rated number.
In an initial state, the use state of the new container in the resource scheduling base is set to be an unoccupied state, so that the service server judges the new container as an idle container of the database type.
Referring to fig. 2, the service server continuously monitors the idle number of containers of each database type in the resource database, and when the idle number of containers of multiple database types meets a preset condition, corresponding reservior events are triggered simultaneously, and the idle number of containers of multiple database types replenished by a container cluster reaches a rated number.
Step S14, in response to the request for creating a container corresponding to a specific type of database, determining an idle target container of a corresponding type from the resource scheduling library, and allocating an access channel credential to the requester of the request for creating:
when a user needs a container of a certain database type for program development or test of the user, a background management page provided by the method triggers a corresponding touch event, so that a creation request for creating the container of a specific database type is sent to a service server, the server responds to the creation request, inquires an idle container matched with the database type from a resource scheduling library according to the database type indicated by the creation request, and allocates an access channel certificate of the idle container to the user.
After the service server sends the access channel certificate of a certain container stored in the resource scheduling library to the user terminal, the use state of the container stored in the resource scheduling library is marked as an occupied state, so that the correct statistics of the idle allowance of the container is ensured.
The user side obtains the network address, the port, the user name and the password of the container which is referred by the access channel certificate by analyzing the access channel certificate sent by the service server; the user can access the working node in the container cluster pointed by the network address by referring to the specific information, a communication link reaching the working node is established through the port, and the corresponding database is accessed by the user name and the password. Currently, as mentioned above, the user name and password are dependent on the specific database type, and are not required.
It can be understood that after the user obtains the access channel credential of the container of a certain database type, the user can directly access the corresponding container in the container cluster by using the access channel credential without passing through the service server, and use the database function provided by the container.
The above exemplary embodiments and variations thereof fully disclose the embodiments of the container dispensing method of the present application, but many variations of the method can be deduced by transforming and augmenting some technical means, and other embodiments are briefly described as follows:
in one embodiment, after a user triggers an event for deleting a certain container on a background management page, a deletion request for deleting the container is sent to a service server, the service server responds to the deletion request, sends a corresponding deletion instruction to a master control node of a container cluster, drives the master control node of the container cluster to delete the container specified by the deletion request, and then notifies the service server. After the service server confirms that the corresponding container in the container cluster is deleted, the corresponding data record of the container in the resource scheduling library can be deleted, so that the data in the resource scheduling pool can be updated in time.
In another embodiment, after a user triggers an event for suspending a certain container on a background management page, a suspension request for suspending access to the container is sent to a service server, the service server responds to the suspension request, sends a corresponding suspension instruction to a master node of a container cluster, drives the master node of the container cluster to suspend the container specified by the suspension request, prohibits the user from accessing the container, and then notifies the service server. After the service server confirms that the container is suspended by the container cluster, the service server can mark the use state of the container in the resource scheduling library as a suspended state.
In another embodiment, after the user triggers an event for restoring a certain container on the background management page, a restoring request for restoring the container is sent to the service server, so that the service server responds to the restoring request, sends a corresponding restoring request to the master node of the container cluster, drives the master node of the container cluster to restore the container specified by the restoring request, allows the user to access the container to continue, and then notifies the service server. After the service server confirms that the container is recovered to be used by the container cluster, the service server can mark the use state of the container in the resource scheduling base as a recovery state.
Each call made by the user to the container for which the user applies can be recorded by the service server. When a user accesses a container applied by the user, the service server records the latest use time stamp of the container through the resource scheduling library so as to send corresponding alarm information to the remote interface when the latest use time stamp of the container of each database type in the resource scheduling library meets a preset condition by monitoring the latest use time stamp of the container.
The service server can know the latest use timestamp generated by the use of a container by a user in various ways, one can automatically send a message to inform the service server when the user accesses the container, the other can send a query instruction to a main control node of the container cluster or a working node where the container is located by the service server and receive a feedback message of the main control node or the working node, and the real-time knowledge can be further obtained through a monitoring synchronization mechanism between the service server and the container cluster. Therefore, those skilled in the art can implement the method flexibly, and detailed description is omitted.
The preset condition that the latest timestamp of the container meets is the preset longest timestamp, when the absolute value of the difference value between the latest timestamp of the container and the current timestamp of the container is larger than or equal to the longest timestamp, the service server can inform a background manager to recover the container, and the manager can decide whether to send an instruction to the service server to indicate the service server to delete or initialize the container according to the condition, so that the resource waste caused by the fact that the occupied container is not used for a long time can be prevented, and the container resources are efficiently utilized.
