Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The container processing method provided by the application can be applied to a container cluster system shown in fig. 1. The container cluster system comprises a plurality of nodes (user terminals), wherein the node corresponding to each user terminal comprises at least one container, the node corresponding to the container cluster management server is connected with other nodes through a network, and the node corresponding to the server terminal is respectively connected with other nodes through the network. The nodes corresponding to the user side may be various types of terminals, specifically, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the container cluster management server and the service side may be implemented by independent servers or a server cluster formed by a plurality of servers.
The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a flowchart of a container processing method according to an embodiment, where an execution subject of the method is a node corresponding to the user side in fig. 1, and the method relates to a specific process in which the user side automatically stores a first target container thereon. As shown in fig. 2, the method specifically includes the following steps (for illustration, the execution subjects of the embodiments in fig. 2-6 are all nodes corresponding to the user side, and are hereinafter referred to as nodes for short):
s101, driving a first target container to send a first instruction to a server; the first instruction carries a first container parameter of a first target container; the interior of the first target container is pre-implanted with an operation tool; the operation tool is used for providing an operation interface for executing the container processing task for a user.
The first target container is a container created in advance by the node, specifically, the node may modify an original container to obtain the created container, optionally, the node may also create a new container again to obtain the created container, as long as an operation tool is implanted in the created container. The first instruction is used to instruct a server connected to the node where the container is located to perform a related operation of processing the container, and specifically, the first instruction may include a container saving instruction, a container creating instruction, a container querying instruction, and the like. The server is used for assisting the node in processing the container according to the first instruction sent by the container on the node. The operation tool is a tool used for users, provides an operation interface for users to execute the container processing task, and after the operation tool is installed, the users can input a command for executing the container processing task through the operation interface provided by the operation tool, so that the containers are processed and information interaction with the server is realized. In addition, while the operation tool provides an operation interface for a user, the operation tool also encapsulates some container commands (also called docker commands) so as to limit the container operation of the user, so that the user can only perform the container operation under the limited condition, and the safety risk brought by the user on the unlimited operation of the container is avoided. Specifically, the operation tool may be a container operation command line tool, so as to provide a container operation interface provided by the container operation command line tool for a user.
In this embodiment, after the first target container is created on the node, the operation tool is installed inside the first target container, and the node may drive the first target container to send the first instruction including the container processing task to the server according to the container processing task instruction input by the user on the operation interface provided by the operation tool, so that the server may execute an operation related to processing the first target container according to the first instruction, and further assist the node to complete a task of automatically processing the first target container.
S102, driving the first target container to receive a container second parameter of the first target container sent by the server according to the container first parameter.
The first container parameter may specifically include at least one of a container IP address, a container host name, and the like. The second parameter of the container includes a container ID, which is a container identifier for identifying the container, and may be specifically represented by numbers, letters, serial numbers, characters, and the like. In this embodiment, when the server receives the first instruction sent by the first target container based on the method of S102, the server may further extract a container first parameter of the first target container from the first instruction, query a container second parameter of the first target container according to the container first parameter of the first target container, and then send the queried container second parameter of the first target container to the first target container, at this time, a node where the first target container is located may drive the first target container to receive the container second parameter of the first target container sent by the server, so that the first target container may perform subsequent container processing operations according to the container second parameter.
And S103, driving the first target container to call a container processing command in the operation tool according to the second container parameter, and performing processing operation on the first target container.
Among other things, processing container commands may include save container commands, create container commands, query container commands, and the like. Specifically, the save container command may include a docker commit command, an export command, and other commands that can save the container environment. In this embodiment, after the first target container receives the container ID, which is the second parameter of the first target container, based on the method in S102, a container processing command, for example, a container saving command (for example, a docker commit command), in the operation tool pre-implanted in the first target container may be called, and a step of performing a processing operation on the first target container is performed according to the second parameter of the first target container, so that the first target container is automatically processed.
In the container processing method provided in this embodiment, a node where a first target container is located drives the first target container to send a first instruction to a server, and then drives the first target container to receive a container second parameter of the first target container sent by the server according to a container first parameter, and then drives the first target container to call a container processing command in an operation tool according to the container second parameter, so as to perform processing operation on the first target container. In the method, since the first target container is implanted with the operation tool in advance, an operation interface facing the user is provided, and the user can issue the container processing task to the container on the node through the operation interface, thereby realizing the information interaction with the server and finally completing the processing task of the container on the node through the information interaction with the server, the whole process is automatically completed by the container cluster system without the information intercommunication between the user and the container cluster administrator, and manual operation to complete the processing of the containers on the nodes, reduces the interaction process between the container cluster administrator and the users, greatly improves the execution efficiency of the container processing work, meanwhile, the problem of container information loss caused by complicated manual container processing by a container cluster administrator and a user is avoided, and the information integrity of the processed container is ensured.
In practical applications, when a user needs to specifically execute a task of saving a container, where the first instruction includes a container saving instruction, and the processing container command includes a container saving command, the "performing a processing operation on a first target container" in S103 in the embodiment specifically includes the steps of: the container environment of the first target container is saved to the mirror image.
In this embodiment, when a user needs to specifically execute a task of saving a container, a container saving request may be issued on an operation interface provided by an operation tool, and the container saving request is converted into a first instruction and sent to a server, where the first instruction carries a first parameter (e.g., a container IP address or a container host name) of the container, and then drives a first target container to receive a second parameter (e.g., a container ID) of the first target container sent by the server according to the first parameter of the container; and then driving the first target container to call a save container command (for example, a docker commit command or an export command) in the operation tool according to the second parameter of the container, and saving the container environment of the first target container to the mirror image.
In practical applications, the first target container needs to be created in advance, so that the first target container has a self-processing function, and therefore, the present application further provides a process for creating the first target container, where the process includes: and modifying the mirror image layer corresponding to the original container to obtain a first target container. In this embodiment, the original container is a container on a node in the container cluster system, and when the node needs to create the first target container, the mirror layer corresponding to the original container on the node may be directly modified to form a new mirror layer, so that the first target container including the new mirror layer may be obtained.
In practical applications, the first target container further needs to be configured with a container environment (docker environment) in advance, so that a container operation command in the operation tool can be performed inside the first target container, and in the application, the step "modifying a mirror layer corresponding to an original container to obtain the first target container" is a specific implementation method, as shown in fig. 3, and the method includes:
s201, adding a new mirror image layer on a mirror image layer corresponding to an original container to obtain a customized mirror image layer; the new mirroring layer includes a script configuration file for the container environment.
Wherein, the new mirror image layer is also called docker in docker layer, i.e. the mirror image layer implanted with docker environment. The customized mirror layer comprises a mirror layer corresponding to the original container and a new mirror layer. In this embodiment, when a node needs to create a first target container, a mirror layer corresponding to an original container may be obtained first, and then a docker in docker layer is added to the mirror layer corresponding to the original container, so as to obtain a customized mirror (as shown in fig. 3A).
S202, creating a first target container according to the customized mirror image layer.
After the node obtains the customized mirror layer based on the method of S201, a first target container may be created according to the customized mirror, and the first target container has a docker environment required by container operation. It should be noted that, after the first target container is created, the docker in the first target container points to the corresponding node where the first target container is located, and all container and mirror image information under the node where the first target container is located may be obtained, so that a user may query any container and mirror image information on the node where the first target container is located later.
In practical application, if a docker command is directly exposed to a container user, the container user can detect other container information of a node where the container is located, and certain security risk exists. Therefore, part of the docker command in the container needs to be packaged to be hidden from a container user, and the application aims at the problem that an operation tool (also called docker command line tool) is implanted in the container in advance to limit the operation of the container user and ensure the safe operation of the container. Based on the application, when the first target container is implanted with the operation tool in advance, the step "modify the original container to obtain the first target container" as shown in fig. 4 includes:
s301, adding an installation package of the operation tool in the environment editing file in the original container.
The environment editing file is also called dockerfile and is used for compiling an installation file of the operation tool, so that the operation tool can be conveniently implanted into the first target container. In addition, when the installation text of the operation tool is written in the environment editing file, the authority can be set for the container operation command contained in the operation tool, so that the condition that all container operation commands are directly exposed to users can be avoided, and potential safety hazards caused by the fact that local users can directly operate containers of other users can be avoided.
In this embodiment, when a node needs to create a first target container, so that the first target container has an operation tool and an interface required by container operation, an installation package of the operation tool may be directly added to the dockerfile of an original container, so that the added dockerfile is executed later to complete automatic installation of the operation tool.
And S302, installing an operation tool in the original container according to the installation package of the operation command tool.
In this embodiment, after the node adds the installation package of the operation tool to the dockerfile of the original container, and then runs the mirror image including the dockerfile, the operation tool may be automatically installed inside the original container to obtain the created first target container, and the first target container has a function operated by the container user, and specifically, the container user may input the container processing task to be executed through the interface provided by the installed operation command line tool, so that the node drives the first target container to execute the corresponding container processing task. In fact, the operation tool provides a channel for the container user to interact information with the first target container, and also provides a channel for the container user to interact information with a server connected with the node. Therefore, the container processing method provided by the application can automatically complete the related tasks of container processing according to the requirements of container users, and compared with the traditional container processing method in a container cluster system, the container processing method also needs to be manually operated by a container cluster administrator to execute the container processing.
In some scenarios, after the container environment of the first target container is saved to the mirror image, the node where the first target container is located may also save the mirror image of the first target container, so that a user may create a corresponding container according to the saved mirror image, and on the basis of the embodiment shown in fig. 2, the step of saving the container environment of the first target container to the mirror image further includes the following steps: adding a label to the mirror image and storing the mirror image in a preset mirror image warehouse; the label comprises a container name, a user name and a storage time stamp corresponding to the mirror image.
In this embodiment, after the node where the first target container is located stores the container environment of the first target container to the mirror image, in order to facilitate the container user to query in the later period, or reuse the mirror image in other nodes in the container cluster system, the node further needs to upload the mirror image to a mirror image warehouse for use by the container cluster, and add a label to the mirror image, where the label is generated by a container name, a user name, and a storage timestamp, so as to ensure the uniqueness of the mirror image.
In some scenarios, before the step S101, the node where the first target container is located needs to generate a first instruction, so that the first target container may send the first instruction to the server. On the basis of the embodiment shown in fig. 2, before the step S101 "driving the first target container to send the first instruction to the server", as shown in fig. 5, the method further includes the steps of:
s401, receiving a container processing command input by a user through an operation interface provided by an operation tool.
In this embodiment, when a user needs to execute a task related to container processing, a command related to container processing, such as a save container command, a create container command, a query container command, etc., may be input on an operation interface on a node where the first target container is located. When the user inputs a process container command on the operation interface, the first target container may receive the process container command. It should be noted that the operation interface is provided for an operation command line tool installed on the first target container.
S402, converting the processing container command into a first instruction.
When the first target container receives a processing container command input by a user, the processing container command can be analyzed, and a first instruction which can be sent by the first target container is generated according to the processing container command, so that a server connected with the node can normally receive the first instruction.
In practical application, when a user needs to specifically execute a task of creating a container, where the first instruction includes a container creation instruction, before "driving a first target container to send the first instruction to a server" in S101 in the foregoing embodiment, as shown in fig. 6, the method further includes:
s501, driving the first target container to call a query command in the operation tool, and querying a preset database to obtain container information of a second target container; the second target container is the container that needs to be created.
The preset database may be a local database on a node, a database built by a server, or a cloud database, and this embodiment is not limited. In this embodiment, when the node where the first target container is located needs to create the second target container, the query command in the operation tool may be invoked first, and the container information needed to create the second target container is obtained by querying from the preset database, so as to be used later.
S502, adding the container information to the container creating instruction so that the server creates a second target container according to the container information carried in the container creating instruction.
In this embodiment, when the node acquires the container information of the second target container that needs to be created, the container information may be added to the container creation instruction, and the container creation instruction is sent to the server, so that the server may execute an operation related to creating the second target container according to the container information carried in the container creation instruction, thereby completing a task of creating the second target container.
The embodiment realizes the automatic container creating function in the container cluster system, when a user needs to create a new container, the first target container can be driven to send a container creating instruction to the server, and the server is instructed to create the new container according to the container information carried in the container creating instruction.

As shown in fig. 7, the method specifically includes the following steps (for explanation, the execution subjects of the embodiments in fig. 7-9 are all nodes corresponding to the server, and are hereinafter referred to as the server):
s601, receiving a first instruction sent by a first target container; the first instruction carries a first container parameter of a first target container; the interior of the first target container is pre-implanted with an operation tool; the operation tool is used for providing an operation interface for executing the container processing task for a user.
