Container port mapping management method, system and equipment and storage medium

Abstract

The invention discloses a container port mapping management method, which is applied to a pre-created proxy container with a network data transmission service and a proxy mapping service, and comprises the following steps: receiving a mapping management command; and configuring a gateway service according to information carried in the mapping management command so as to perform mapping binding management between the host machine port and the application container port. By applying the scheme of the invention, the management of container port mapping can be conveniently and effectively realized, and the management is not related to the state of the application container. The invention further provides a container port mapping management system and device and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a container port mapping management method, system, device and storage medium. Background technique [0002] At present, the containerized deployment of applications can be carried out through the container management platform, which greatly facilitates the deployment of applications. When the online environment uses the container image to create a container, it will declare that the created container is mapped to the port of the host machine. Creating a container can modify the mapping configuration between container ports and host ports. [0003] For a stateless application container, it is relatively easy to modify the port mapping configuration by rebuilding, but it is not feasible for a stateful application container, because the state or data recovery delay after the container is rebuilt will inevitably lead to Disruption of service, which can be catastrophic in ...

AI Technical Summary

Problems solved by technology

However, whenever the network address changes when the container restarts, it is necessary to re-modify the nat traffic forwarding rules. At the same time, a large number of Iptables policies lead to network delays and configuration conflicts during the forwarding process, that is, rule conflicts are easy to occur, resulting in The port mapping rules are invalid, so the Iptables method can only be used as a temporary solution, and it is not stable in the production environment
