Cross-host mutual access system based on docker containers and control method thereof

Abstract

The invention discloses a cross-host mutual access system based on docker containers and a control method thereof. The system comprises a host and a plurality of node hosts. The host and the node hosts are connected through a network. A database is arranged on the host. The host detects a connection operation state of each node host periodically, issues updating messages and allocates IP address or network segments. Each node host receives a route configured with an IP address segment employed by other node container. A next hop address of the route is an interface IP address of the node host. Each node host carries out route configuration on a network device connected with the node host, so the whole cross-host mutual access system forms pure static route configuration and each node route can be directly checked and modified. The docker containers in the system can carry out mutual access with a traditional physical network, also can carry out cross-host mutual access, are safe and reliable and are easy to maintain. The package of a server for data packages is greatly reduced. The performance consumption resulting from the package is reduced.

Description

technical field [0001] The present invention relates to a cross-host mutual access system and a control method thereof, in particular to a cross-host mutual access system based on a docker container and a control method thereof. Background technique [0002] At present, there are two solutions for mutual access between docker containers: [0003] 1. Routing scheme [0004] The routing scheme is represented by calico. By running the BGP routing protocol on the host of each container, a network that can transfer container IP routes is formed, and then the container communication between different hosts is achieved by querying the local BGP routing of the host. Addressing of the data path is performed. [0005] If you want the container to communicate with the physical network, such as switches, routers, or other devices that are not containers, you need to enable the BGP routing protocol on the network device, and establish a BGP neighbor connection with the host of other co...

Problems solved by technology

[0014] The technical problem to be solved by the present invention is to provide a docker container-based cross-host mutual access system and its control method, which can make full use of the advantages of the routing scheme and the tunneling scheme, and solve the problem caused by the lack of support of BGP or other routing protocols in the data center. The problem that the cross-host hosts cannot communicate with each other
