The invention provides a cross-host communication method and a cross-host communication system for a Docker container. The method comprises the steps as follows: an OVS network bridge is built after a control Docker starts; network configuration information of an application Docker is acquired after the control Docker detects that the application Docker on a host starts; the control Docker sends the network configuration information to a distributed coordination service for storing, and the distributed coordination service is used for maintaining the network configuration information of the application Docker on each host in networking; the control Docker generates a forwarding flow table according to the updated network configuration information when monitoring that the network configuration information of the application Docker in the distributed coordination service is updated; the control Docker issues the forwarding flow table to the OVS network bridge; and the OVS network bridge guides cross-host communication between the application Dockers according to the forwarding flow table.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a method and system for cross-host communication of a Docker container. Background technique [0002] The Docker container is an open source application container engine that allows developers to package their applications and dependencies into a portable container, and then publish it to any popular Linux machine, and can also implement virtualization. [0003] In related technologies, Docker containers natively provide three network models, namely bridge, host, and none. Among them, the bridge model and none model cannot realize cross-host communication of Docker containers. Although the host model can realize cross-host communication, it cannot simultaneously achieve network isolation between Docker containers on the same host host. Contents of the invention [0004] In view of this, the present application provides a method and system for cross-host com...
