Network high availability method and device based on docker

Abstract

The invention discloses a network high available method and device based on a docker and relates to the technical field of a device or method for performing a special program. The method comprises the steps of setting virtual network card devices; adding a docker container network device; and bridging container network cards to the virtual network card devices through network bridge network cards. The method is based on a none network mode of the docker. The bridge network cards are added in a network plug-in mode. In a mode of linking the virtual network cards bonded with ports through the bridge network cards, various containers are supported to enjoy independent networks and independent IPs and do not share ports. Links are redundant, traffic loads are balanced, and the traffic bandwidth is increased. Through application of the method, the purchase cost of establishing a container virtualized system platform is reduced, and moreover, the reusability of server resources on operation of the same kinds of applications is improved.

Description

technical field [0001] The present invention relates to the technical field of devices or methods for executing special programs, in particular to a docker-based high-availability method and device for a network. Background technique [0002] The high-availability technology method of the container network is mainly used to provide fixed IP addresses for docker services and running containers in the system, as well as security mechanisms for network link redundancy and load balancing. [0003] At present, most of the link redundancy solutions for docker container virtualization on the market are completed by traditional hardware manufacturers. At the hardware level, at the driver level, link redundancy is completed through the built-in management controller, allowing the operating system to directly recognize virtualization. After the network card device. Usually such high-end servers that support hardware virtualization are more expensive than general-purpose servers. As ...

Problems solved by technology

However, this mode must bind the host IP address and port, and the port of the container mapping service cannot be the same

[0011] None of the above four official network modes provided by docker can support containers with independent IP addresses, can access each other, and do not limit service ports. At the same time, the network links are redundant and highly available, and traffic load balancing requirements
