Method for setting static IP (Internet Protocol) in Pod in Kubernetes

Abstract

The invention discloses a method for setting a static IP (Internet Protocol) in Pod in Kubernetes. The method comprises the following steps: firstly, a Pod network management function is realized based on a Kubernetes cluster platform, and when workflows such as container network creation, container IP distribution, container IP recovery and the like need to be realized, if the container network needs to be created through the network management platform, the method relates to the technical field of system framework construction. According to the method for setting the static IP in the Pod inthe Kubernetes, the static IP is set; a Mysql cluster 5 is queried; a specified container network configuration is acquired; the corresponding IP record in the Mysql is updated; the fact the Pod IP record has been used is identified; meanwhile, a query result is returned to the network plug-in; after the network plug-in receives the network configuration of the container, a Network Namespace technology of Linux is adopted to switch to a Network Namespace of a container, the specified network configuration is configured for the container, and the use mode of the Pod IP is fixed, so that the efficiency of migrating the application to the Kubernetes cluster can be improved, the maintenance cost is reduced, and the method and the system are compatible with the modes of deploying the application and operating and maintaining the application by a user to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of system framework construction, in particular to a method for setting a static IP in a Pod in Kubernetes. Background technique [0002] Kubernetes is a container cluster management system, which can simplify application workflow and speed up development. Through Kubernetes technology, container-based application deployment, maintenance and rolling upgrade can be realized; load balancing and service discovery; cross-machine and cross-region Cluster scheduling; automatic scaling; stateless services and stateful services; multiple types of Volume support; support for declarative configuration files to manage the entire life cycle of containers and other functions. Due to the flexibility of Kubernetes management containers, it is necessary to migrate to Kubernetes The services on the cluster are transformed to meet the application deployment specifications in the Kubernetes cluster. The contents that need to b...
