Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a method, a system, a device, and a storage medium for managing container port mapping.
Background
At present, the container deployment of the application can be performed through the container management platform, which greatly facilitates the deployment of the application, when the container is created by using the container mirror image, the online environment declares that the created container is mapped to the port of the host, and the mapping configuration from the container port to the port of the host can be modified by re-creating the container.
It is relatively easy to modify the mapping configuration of ports by means of rebuilding for stateless application containers, but not feasible for stateful application containers, since state or data recovery delays after rebuilding a container necessarily lead to service outages, which are catastrophic in a production environment.
Currently, it is more applicable to configure nat traffic forwarding rules through an Iptables tool built in the Linux system, so as to map a host port to a container port. However, each time the container is restarted, the network address is changed, and the nat traffic forwarding rule needs to be modified again, and meanwhile, a large number of Iptables policies cause network delay and configuration conflict in the forwarding process, that is, rule conflict is easy to occur, and the port mapping rule is invalid, so that the Iptables method can only be used as a temporary scheme and has no stability in a production environment.
In summary, how to conveniently and effectively implement container port mapping is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description
The core of the invention is to provide a management method of container port mapping, which can conveniently and effectively realize the management of the container port mapping and is irrelevant to the state of an application container.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for managing a container port mapping according to the present invention, where the method for managing a container port mapping is applied to a pre-created proxy container having a network data transmission service and a proxy mapping service, and includes the following steps:
step S101: a mapping management command is received.
In the scheme of the application, the proxy container is provided with the network data transmission service, so that data transmission between the host and the application container can be realized, and the proxy mapping service is also provided, so that mapping management can be realized.
The agent container may be deployed in a server, and in practical applications, a server cluster is generally formed by a plurality of server nodes, and then each server may configure 1 agent container to implement the solution of the present application.
Because containerized deployment of applications is required, a container application platform is required to be built in a server, most of applications and dependency packages can be packaged into a portable mirror image considering that docker is an open-source application container engine, and then the application and dependency packages are released to any popular Linux server, so that the deployment of undifferentiated testing and release basic environments can be realized, and meanwhile, virtualization can also be realized. Therefore, in the scheme of the application, the container management platform built in the server can be a docker container management platform. In addition, when a network management environment is deployed, a sweep environment is typically deployed.
The staff can input the mapping management command, the mapping management command can carry the specific operation content of the mapping management required at this time, and the proxy container receives the mapping management command.
Step S102: and configuring gateway service according to the information carried in the mapping management command so as to perform mapping binding management between the port of the host machine and the port of the application container.
After the proxy container receives the mapping management command, the gateway service can be configured according to the information carried in the mapping management command. The gateway service can determine the mapping relation between the port of the host machine and the port of the application container, so that the mapping binding management between the port of the host machine and the port of the application container can be carried out by modifying and configuring the gateway service, and the gateway service is irrelevant to the state of the application container and does not have the condition of rule conflict.
In a specific embodiment, the gateway service may be specifically a nginx gateway service. When nginx is adopted as gateway service, the installation is simple, the configuration file is concise, and the starting is easy. Correspondingly, step S101 may specifically include: a mapping management command is received through the RESTAPI interface.
REST (representationstate Transfer, REST) describes an architecture style network system, and sets a set of architecture constraints and principles, and an application or design that satisfies these constraints and principles is RESTful. RESTAPI (Application Programming Interface), a RESTful API, indicates an Interface based on REST rules.
In this embodiment, the proxy container may receive the mapping management command through the RESTAPI interface, and further may configure the nginx gateway service in the RESTAPI manner, that is, the proxy container is a container that manages the configuration of the nginx gateway service in the RESTAPI encapsulation manner, so that mapping binding management between the host port and the application container port may be performed.
When performing mapping binding management between a host port and an application container port, the mapping binding management may generally specifically include: the addition, modification or deletion of mapping binding between the host port and the application container port is also a common operation in the management of container port mapping.
In one embodiment of the present invention, the mapping management command is a command line selected from a dynamic mapping program created in advance and uploaded to the server.
In the implementation mode, in order to conveniently input the mapping management command, a dynamic mapping program, which may be called a port program, is created in advance and uploaded to the server, so that a corresponding command line can be directly selected from the dynamic mapping program in the following step to serve as the currently required mapping management command, which is simple and convenient.
For example, in one embodiment of the present invention, a command line of a previously created maprt program may be sent to the RESTAPI interface and identified, and the following is a description of the maprt program in one embodiment:
NAME：maport
SYNOPSIS：maport[OPTIONS][VALUE]

It can be seen that, in this embodiment, when the mapping binding between the host port and the application container port needs to be increased or modified, the mapping management command may be implemented by a map port-p [ host _ port ], [ container _ port ] -n [ container _ name ], where-n [ container _ name ] in the mapping management command is used to specify the application container that needs to be operated at this time, and p [ host _ port ], [ container _ port ] is used to specify the host port and the port of the application container. And the mapping management command of map port-d host port, container port, n container name can delete the mapping binding between the host port and the application container port.
In this embodiment, the proxy container may be created by the command line of the maport program, or the proxy container may be uninstalled. That is to say, the agent container may be an agent container installed through a dynamic mapping program, so that when a worker executes the scheme of the application, the worker only needs to create the dynamic mapping program in advance and upload the dynamic mapping program to the server, and then various required operations, including creation and uninstallation of the agent container, and addition, deletion and modification of mapping binding between the host port and the application container port, may be implemented based on the dynamic mapping program.
In one embodiment of the present invention, the method further comprises: and after receiving a server state query command, querying and feeding back a current port mapping relation list of the server.
In this embodiment, the addition, deletion, and modification of the mapping binding between the host port and the application container port are performed by the staff conveniently. The current port mapping relation list of the server can be displayed, so that the work of workers is assisted. In the foregoing embodiment, the command line-l/list of the maport program can be used to implement, that is, the command line-l/list can be used as a server status query command.
