Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 1 is a flow chart of a configuration modification method of a container application provided in an embodiment of the present application. As shown in FIG. 1, the method includes S101-S107.
S101, if a configuration modification instruction of a container application is received, calling a preset modification interface according to the configuration modification instruction so as to receive configuration information to be modified of the container application, which is set through the preset modification interface.
The configuration modification instruction of the container application can be triggered in various modes, such as by clicking or triggering a button or an image by a user, for example, clicking a configuration modification button corresponding to a certain container application in a list of container applications to trigger the configuration modification instruction of the container application; such as by receiving a voice configuration modification message from a user to trigger a corresponding configuration modification instruction. The configuration modification instruction includes information of the container application, such as identification information of the container application. The identification information of the container application may be the name of the container application or the number of the container application, etc. information that can determine which container application is specific. The preset modification interface is called according to the configuration modification instruction, and the preset modification interface is developed by a developer and can exist in the form of a setting interface. The configuration information to be modified of the container application can be set through a preset modification interface. It can be understood that the configuration information to be modified of the container application can be set through the preset modification interface, so that the configuration information to be modified is very transparent, the configuration information to be modified can be intuitively seen, and the experience of a user is improved. And the setting can be performed by simple selection/input operation, high expertise of a user is not required, and labor cost and time cost are reduced.
The configuration information to be modified by the container application includes resource information to be modified by the container application, mirror information to be modified by the container application, and the like.
The resource information to be modified by the container application includes CPU resources (such as the number of cores of the CPU), memory resources (such as memory capacity) and the like occupied by each container instance of the container application. Wherein the resource information of the container application may be determined in two ways: firstly, obtaining the flow of the container before application; estimating resource information required by the container application according to the past flow and the current flow of the container application; and determining the estimated resource information as the resource information of the container application. Or determining resource information of the container application according to the prior flow peak of the container application. For example, the resources presumably required by the container application may be estimated according to the past flow peak of the container application, for example, the past flow peak requires 2 core 4G memory, and the resource information of the container application includes 2 core 4G memory. And (II) acquiring the common configuration of the container application stored in the platform, and determining the common configuration as the resource information of the container application. Such as webogic applications, typically require 2-core 4G memory, then 2-core 4G memory is a common configuration for webogic applications. That is, the weblogic application will typically be set to 2-core 4G memory. It should be noted that the common configuration of the container application is set by the user according to the business scenario of the company, i.e. the common configuration is tailored to the business scenario of the company. After the resource information of the container application is determined, the resource information of the container application is displayed on a preset setting interface, so that a user can set the resource information to be modified of the container application according to the displayed resource information of the container application. As in an embodiment, the user may directly set the displayed resource information of the container application as the resource information to be modified by the container application. In one embodiment, the resource information of the displayed container application is set as the resource information of the default container application; if the modification of the resource information of the default container application by the user is received, acquiring the resource information modified by the user; and taking the acquired resource information modified by the user as resource information to be modified. In some embodiments, the resource information of the container application also includes DNS server information, which is typically determined by the architecture of the enterprise, and is typically not modified.
The image information of the container application includes an image type and an image name of the container application. The mirrored information of the container application may be determined as follows: determining a mirror type, such as acquiring a plurality of candidate mirror types from a database, and receiving a mirror type selected by a user from the plurality of candidate mirror types; determining a specific image according to the image type, for example, acquiring all candidate images under the image type from a database according to the image type (it can be understood that a plurality of different image versions exist under the image type); and receiving one image selected by the user from the candidate images as a specific image, and acquiring the image name of the specific image. And taking the image type and the specific image selected by the user as image information to be modified. It should be noted that if the image information to be modified by the container application is empty, the image information of the container application may be considered not to be modified.
It will be appreciated that the configuration information of the set container application to be modified may include only one of the configuration information, such as only mirror information to be modified, only resource information to be modified, only a CPU in the resource information to be modified, only a memory in the resource information to be modified, and the like.
S102, if a setting completion instruction is received, acquiring configuration information to be modified of the container application.
The setting completion instruction may be triggered in various manners, such as by a user clicking or triggering a button or an image, such as by a user clicking a corresponding button or image, such as a "submit" button, a "confirm" image, etc.; such as by receiving a voice determination message from the user to trigger a corresponding setup completion instruction. And after receiving the setting completion instruction, acquiring configuration information to be modified of the container application.
S103, detecting whether the mirror image information to be modified in the configuration information to be modified is consistent with the mirror image information applied by the container.
Wherein all information of all container applications is stored in the database. And determining which container application is according to the identification information of the container application in the configuration modification instruction, and acquiring various information of the container application from a database according to the identification information of the container application. Such as obtaining mirror information for the container application stored in the database. And matching the obtained mirror image information of the container application with the mirror image information with modification in the configuration information to be modified so as to determine whether the mirror image information to be modified is consistent with the mirror image information of the container application stored in the database. If the mirror image information to be modified is empty, determining that the mirror image information to be modified is consistent with the mirror image information of the container application; if the mirror image information to be modified is not empty, but the mirror image information to be modified is the same as the mirror image information of the container application, determining that the mirror image information to be modified is consistent with the mirror image information of the container application; otherwise, if the image information to be modified is different from the image information of the container application, determining that the image information to be modified is inconsistent with the image information of the container application. The image information to be modified is the same as the image information applied by the container, and the image type and the image name are the same. If one of the image type and the image version is different, the information is considered to be different, that is, the image information to be modified is inconsistent with the image information of the container application.
If the mirror image information to be modified is inconsistent with the mirror image information of the container application, executing step S104; if the image information to be modified is consistent with the image information of the container application, step S106 is executed.
S104, the binding relation between all container instances of the container application and corresponding container instance IP is released, and all container instances are destroyed.
The binding relation between the container instance of the container application and the container instance IP is released, and then the container instance of the container application is destroyed.
In one embodiment, as shown in FIG. 2, step S104 includes the following steps S1041-S1043.
S1041, determining the host where all container instances of the container application are located.
And storing the information of the host machines of all the container instances of the container application in a database, and acquiring the host machines of all the container instances of the container application from the database. If the information of the container application is obtained from the database according to the identification information of the container application, the host machines where all container instances of the container application are located are obtained from the database according to the information of the container application. Typically, a container instance corresponds to a host. If there are multiple container instances, the host machine corresponding to the multiple container instances is obtained. It should be noted that the host may also include multiple container instances of other applications thereon.
S1042, the binding relation between the container instance of the container application on the host and the corresponding container instance IP is released.
The database stores information such as container instance IP of the container application. The container instance can access the container application through the IP only after the container instance IP is set. And acquiring the container instance IP information of the container application from the database, and determining the container instance of the container application on the host machine according to the container instance IP information of the container application. The binding relationship between the container instance of the container application on the host and the corresponding container instance IP is released, and the method can be realized by the following steps: and connecting the container instance of the container application through an automatic operation and maintenance tool, and unbinding the container instance of the container application and the container instance IP. Specifically, the container instance of the container application is connected through an automatic operation and maintenance tool, and an instruction for deleting the network card is issued to delete the network card of the container instance of the container application. The automated operation tool may be an existing tool, or may be another tool that may implement the same function. After the binding relationship between the container instance of the container application and the container instance IP is released, the IP state of the container instance is also changed, such as modifying from a use state to a disabled state. In other embodiments, the binding of the container instance of the container application on the host to the corresponding container instance IP may also be resolved in other ways.
It should be noted that, before unbinding the container instance of the container application on the host from the corresponding container instance IP, the method further includes: and stopping the running of the container instance of the container application on the host. Such as by executing instructions to stop the execution of container instances, such as a docker stop instruction.
S1043, destroying the container instance of the container application on the host machine and recovering the resource of the container instance.
And e.g. issuing a destroying instruction to a host machine where the container instance of the container application is located through a container arranging tool so as to destroy the container instance of the container application on the host machine and recover the resources of the container instance. The destroying container instance releases and recovers all the resources occupied by the container instance, such as CPU resources, memory resources, environment information corresponding to the container instance, file input/output stream (closed), connection with database (closed), and the like. Among them, orchestration tools such as marathon, etc. Specifically, the resources of the container instance are destroyed, and it is understood that the process of the container instance on the corresponding host machine is stopped (kill operation). Once kill has the process, it indicates that the container instance does not already exist on the host, nor does it occupy any resources on the host. It will be appreciated that one container instance corresponds to one process.
The embodiment realizes that the binding relation between all container instances of the container application and corresponding container instance IP is released and all container instances are destroyed automatically, and provides the speed of releasing the corresponding binding relation and destroying the container instances.
S105, creating a new container instance according to the resource information to be modified and the mirror image information to be modified in the configuration information to be modified, and binding the created new container instance with a corresponding container instance IP to complete modification and replacement of the mirror image information of the container application.
The corresponding container instance IP is the IP bound by the destroyed container instance. The number of created new container instances is equal to the number of destroyed container instances. Creating a new container instance and binding the created new container instance with the corresponding container instance IP. Therefore, the IP bound by the destroyed container instance is directly used without distributing the container instance IP for the new container instance, and the speed of modifying and replacing the mirror image information of the container application is improved.
In one embodiment, as shown in FIG. 3, step S105 includes the following steps S1051-S1054.
S1051, determining an image warehouse under the area where the container is applied, and acquiring a specific image from the determined image warehouse according to the image information to be modified.
Such as the application environment of the container application, the region of the container application, is saved in the database. And determining a mirror warehouse under the area of the container application according to the application environment of the container application and the area of the container application. Specifically, according to the application environment of the container application and the region of the container application, searching a mirror warehouse under the region of the container application from a database. It is understood that one mirror repository is defined per application environment, per region. And each region in each application environment corresponds to a mirror image warehouse for storing mirror image resources, and all the mirror image resources required to be used in the region in the application environment are stored in the mirror image warehouse. The application environment comprises a production environment, a test environment, a development environment and the like. After the mirror image warehouse is determined, a specific mirror image is extracted from the mirror image warehouse according to the type and the name of the mirror image in the mirror image information to be modified.
In one embodiment, the mirrored repository under the region where the container application is located may be obtained directly from the database based on the identification information of the container application.
S1052, determining a host for creating a new container instance of the container application according to the mirror image information to be modified and the resource information to be modified.
If the application environment of the container application and the area of the container application can be obtained in the database, the host cluster is determined according to the application environment of the container application and the area of the container application, for example, the host cluster under the area of the container application is obtained from the database according to the application environment of the container application and the area of the container application. In one embodiment, the host cluster under the area where the container application is located may be obtained directly from the database according to the identification information of the container application. After the host cluster is acquired, determining a host for creating a new container instance of the container application according to the mirror information to be modified and the resource information to be modified. The method comprises the steps that a container instance is created, resources of a host are required to be occupied, and resources required to be occupied for creating a new container instance are determined according to the information of the resources to be modified and the mirror image information to be modified; and determining the host machine for creating the new container instance from the host machine cluster under the area where the container application is located according to the resources required to be occupied for creating the new container instance.
It should be noted that the determined host that created the new container instance is randomly assigned and not necessarily the host where the destroyed container instance is located. It will be appreciated that the mirrored information of the application creating the container has changed, and thus, the resources required to create the container instance may also have changed, and if a new container instance is also created on the host where the destroyed container instance is located, there is a high probability that there is insufficient host resources where the destroyed container instance is located, resulting in failure of creation of the new container instance. Thus, the hosts that create the new container instances are randomly allocated according to the resources that need to be occupied to create the new container instances, and thus, there is no shortage of resources for the randomly allocated hosts.
It should be noted that if the resource information to be modified in the step is all empty, the resource information of the container application is directly obtained, the resource information of the container application is used as the resource information to be modified, which means that only the mirror image information of the container application is modified, and the resource information of the created new container instance is the same as the resource information of the destroyed container instance; if a part of the resource information to be modified is empty, the empty part directly uses the corresponding resource of the container application, and if the part is not empty, the information in the resource information to be modified is used; and if the resource information to be modified is not empty, directly using the resource information to be modified.
S1053, creating a new container instance on the determined host according to the specific mirror image and the resource information to be modified.
If the resource information to be modified is packaged, the packaged resource information to be modified and the specific mirror image are sent to the determined host machine through the container arrangement tool, so that the creation of the container instance is carried out on the determined host machine through the container arrangement tool. Specifically, an API function interface, such as a creation interface, in the container orchestration tool is invoked to enable creation of the container instance. The container arranging tool can be a Marathon tool, and can also be other container arranging tools. It should be noted that how many container instances the container application destroys, and then how many container instances are newly created there.
S1054, binding the created new container instance with the corresponding container instance IP.
The created new container instance is connected, such as by an automated operation tool, and bound with the corresponding container instance IP to set the destroyed container instance IP as the created new container instance IP. Wherein, the automated operation tool can be an allowable tool and the like. After the IP is bound with the container instance, the state of the IP is also modified, such as changing the state of the IP from a deactivated state to a used state.
It should be noted that if a container application has multiple container instances, then the container instances on multiple hosts are obtained, each with a replacement of the application image. In this way, the application image of all container instances of the container application can be replaced at one time without requiring a container instance to be replaced one by one.
The embodiment provides a brand new technical thought and technical scheme for quickly replacing the service of the container application by modifying the mirror image information of the container application directly on the basis of the container application, can be realized in seconds, and achieves unexpected technical effects. In addition, the embodiment creates a new container instance according to the mirror image information to be modified and the resource information to be modified, binds the new container instance with the destroyed container instance IP, and improves the speed and efficiency of the replacement of the application mirror image of the container by automating the process.
The steps S104-S105 can realize the application image of the modified container application, namely, the image information of the container application is replaced by the image information to be modified, so that the quick switching or the construction service can be achieved, and meanwhile, the IP of the container instance is kept unchanged. Or can be understood as replacing only the application image or application service of the container application, and the service replacement can be realized quickly and in a second level without changing the other.
S106, detecting whether the resource information to be modified in the configuration information to be modified is consistent with the resource information of the container application.
If the mirror image information to be modified is consistent with the mirror image information of the container application, determining that the mirror image information of the container application is not changed, and detecting whether the resource information to be modified is consistent with the resource information of the container application. If the resource information of the container application is obtained from the database according to the identification information of the container application, matching the obtained resource information of the container application with the resource information to be modified so as to determine whether the resource information to be modified is consistent with the resource information of the container application. If the resource information to be modified is empty, determining that the resource information to be modified is consistent with the resource information of the container application; if the resource information to be modified is not empty, but the resource information to be modified is the same as the resource information of the container application, determining that the resource information to be modified is consistent with the resource information of the container application; otherwise, if the resource information to be modified is different from the resource information of the container application, determining that the resource information to be modified is inconsistent with the resource information of the container application. The resource information to be modified is the same as the resource information of the container application, which can be understood that all the information in the resource information to be modified is the same, and if one of the information is different, the information is considered to be different, that is, the resource information to be modified is inconsistent with the resource information of the container application.
If the resource information to be modified is inconsistent with the resource information of the container application, executing step S107; if the resource information to be modified is consistent with the resource information of the container application, that is, the mirror image information to be modified is consistent with the mirror image information of the container application, and the resource information to be modified is also consistent with the resource information of the container application, this means that the configuration information of the container application is not modified, and the process is ended.
And S107, modifying the resources of the container application according to the resource information to be modified so as to complete the modification of the resource information of the container application.
And acquiring the resource information of the container application from the database, and modifying the resource of the container application on the corresponding host according to the acquired resource information of the container application and the set resource information to be modified. If the resource information to be modified and the acquired resource information of the container application are different, determining the resource information which is required to be added/deleted for the container application. If the memory in the original resource information is 2G and the memory set in the resource information to be modified is 4G, then it is determined that the newly added memory resource 2G is to be applied to the container, that is, the newly added memory resource 2G is to be applied to the container on the corresponding host. If the memory in the original resource information is 4G and the memory set in the resource information to be modified is 2G, determining that the memory resource 2G is deleted for the container application, that is, releasing the memory resource 2G corresponding to the container application on the corresponding host. In this manner, the resource information of the container application is updated to ensure that the resources of the container application are sufficient for use of the container application.
It should be noted that if a container application has multiple container instances, then the container instances on multiple hosts are obtained, each modified.
In addition, the method does not need to log on the corresponding container instance to modify, does not need to put forward requirements on the professional degree of the user, and improves the experience of the user.
In an embodiment, as shown in fig. 1, the method further includes:
s108, updating the configuration information modified by the container application into a database.
Such as updating the modified resource information and/or the modified application image information into the database to ensure that the data in the database is synchronized in real time.
In an embodiment, as shown in fig. 1, the method further includes:
s109, restarting the container application to enable configuration modification of the container application to be effective.
The embodiment of the method can modify the corresponding configuration of all container examples of the container application at one time, and the configuration modification process is automatically completed, so that the speed of configuration modification of the container application is increased, the requirement on the professional degree of a user is not required, the user experience is improved, and the labor cost and the time cost are reduced. Specifically, if the application mirror image of the container application can be replaced, the service of the container application is replaced, and the speed of building the service is improved; such as resource information for a container application that can be quickly modified. In addition, the configuration information to be modified is intuitively set through the corresponding preset setting interface, so that the setting of the configuration information to be modified is very transparent, the requirement on the professional degree of a user is not required, and the user experience is improved.
Fig. 4 is a schematic block diagram of a configuration modification apparatus of a container application provided in an embodiment of the present application. The device comprises a unit corresponding to a configuration modification method for executing the container application. As shown in fig. 4, the configuration modification apparatus 100 of the container application includes a setting unit 101, an information acquisition unit 102, a mirror detection unit 103, a destruction unit 104, a creation unit 105, a resource detection unit 106, and a resource modification unit 107.
