Abstract

The invention discloses a method for inter-host Docker container communication, which is characterized in that it comprises the following steps: S1: creating a Docker container whose network mode is Docker Bridge; S2: adding a Calico network configuration to the Docker container; S3 : delete the default route of Calico in the Docker container; S4: add a policy route for the Calico-related route in the Docker container. The beneficial effect of the present invention is: the present invention adopts the development mode that combines Calico and Docker Bridge, makes up for the defect that Calico cannot map ports in Docker, solves the problem that Docker containers on different hosts communicate with each other at the same time, makes Docker container It can not only communicate with the external network, but also communicate with Docker containers on different hosts in the internal network.

Description

technical field [0001] The invention relates to a Docker container communication method, in particular to a cross-host Docker container communication method. Background technique [0002] Currently, existing container network solutions include tunneling solutions, routing solutions, CNM (Docker Libnetwork Container Network Model) camps, CNI (Container Network Interface) camps, and Calico. [0003] Among them, the tunnel solution is widely used in the network application of the LaaS layer, but the complexity will also increase with the increase of the node scale, which makes it more troublesome to track network problems, so the tunnel solution is not suitable for large-scale clusters; CNM includes Docker Swarm Overlay, Macvlan&IP network drivers, Calico, Contiv (from Cisco), the advantage of Docker Libnetwork is that it is native, and it is closely integrated with the life cycle of Docker containers. The disadvantage can also be understood as being "kidnapped" by Docker; CNI ...
