Problems solved by technology

Docker clusters generally use the Overlay mode that supports multi-host communication when creating containers. External access to container services must use port mapping, which has a fatal flaw of insufficient host ports.

Embodiment Construction

[0013] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0014] A method for configuring the external IP of a Docker cluster container in this solution includes the following steps:

[0015] 1) The host builds a Docker cluster environment, configures the basic information of the external network, creates a data table and saves the information in the background database, and at the same time, the Docker host selects the first external IP to create a route, and the database records the external IP; the basic information includes classless inter-domain Routing selects CIDR segments, gateways, and available IP segments.

[0016] 2) When creating a container in a Docker environment, you need to apply for an external IP, and the background database retrieves the data table to allocate an available IP; send the IP and routing information to the host where the container is located to ...

Abstract

The invention provides a configuration method for an external IP of a Docker cluster container, and the method can ensure that services provided by the Docker cluster container can be accessed flexibly in the external. A Docker cluster environment is initialized, and the external IP is configured and sent to a background database for storage; and a host establishes a route. After establishment of the container, a Docker cluster is distributed with the external IP which can be accessed by the external, and a background database records a mapping relation. The Docker cluster destroys the container and deletes Linux Iptables rules, and the background database deletes records and recovers the external IP.

Description

technical field [0001] What the present invention relates to is a kind of technology of computer software application, especially a kind of method based on Linux Iptables rule and Mariadb database configuration Docker cluster container external IP, guarantees the service that can visit Docker cluster container flexibly outside. Background technique [0002] In the existing technology, the well-known technology is that Docker is an open source engine, which can easily create a lightweight, portable, and self-sufficient container for any application. The containers that developers compile and test can be batched in Deployed in a production environment, including virtual machines, OpenStack clusters, and other basic application platforms. Docker clusters generally use the Overlay mode that supports multi-host communication when creating containers. External access to container services must use port mapping, which has a fatal flaw of insufficient host ports. Therefore, we need...
