Safety control method of communication between containers and safety control device of communication between containers

Abstract

The invention provides a safety control method of communication between containers and safety control device of communication between containers. The safety control method comprises steps that a first virtual container gateway is used to receive an access request transmitted by a source Docker container; the first virtual container gateway is used to acquire address information of a second virtual container gateway corresponding to the first virtual container gateway, and the second virtual container gateway is corresponding to a target Docker container; the first virtual container gateway is used to transmit the access request to the second virtual container gateway according to the address information of the second virtual container gateway, and then the second virtual container gateway is used to forward the access request to the target Docker container. The directional communication between the Docker containers is realized by the directional communication between the virtual container gateways, and therefore the reliability of the communication between the Docker containers is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication, and in particular, to a security control method and device for inter-container communication. Background technique [0002] Docker is an open source application container engine. After installing Docker on a physical host, multiple containers can be hosted on the basis of Docker. Multiple containers are isolated from each other. Multiple containers share the operating system of the physical host, and each container can be placed and execute different applications. [0003] The physical host on which the Docker container is installed is called a Docker server. For example, Docker container 1 is in Docker server 1, and Docker container 2 is in Docker server 2. When Docker container 1 needs to access Docker container 2 as a client, Docker container 1 is created Request message, the source IP address of the request message is the IP address of Docker server 1, and the des...

AI Technical Summary

Problems solved by technology

[0004] However, when Docker container 2 is migrated from Docker server 2 to other Docker servers, Docker container 1 will not be able to communicate with Docker container 2, which reduces the reliability of communication between Docker containers, and thus cannot guarantee the directional communication between Docker containers
