Abstract

The invention provides a container creation method, a server and a storage medium. The method comprises the following steps of enabling the first server to create a target network resource with a state service, setting at least one piece of IP address indication information in the configuration file according to the editing operation of the configuration file for the target network resource, enabling the second server to call an application service interface in the first server to obtain a configuration file of the target network resource, and reading at least one piece of IP address indication information in the configuration file, obtaining at least one IP address, determining an unused IP address from the at least one IP address according to a preset storage file, and creating a targetcontainer according to the unused IP address. Compared with the prior art, the method has the following beneficial effects that the client accesses the container on the server in a fixed IP manner byproviding the fixed IP address for the container, so that the problem of access failure caused by cache delay of the mapping relationship between the domain name and the IP address is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a method for creating a container, a server, and a storage medium. Background technique [0002] As a workload that can provide stateful services in Kubernetes, StatefulSet has been widely used in the industry. In a stateful service, external services need to access the stateful service through a fixed network address. However, in the Kubernetes environment, as the container is updated and restarted, the Internet Protocol (IP) address of the container will change. Therefore, it is impossible to provide a stable IP address to the outside world. [0003] The current solution provided by the community is: provide a domain name for each container under the StatefulSet, and bind the domain name to the container. When the IP of the container changes, the domain name resolution is updated accordingly, so that the domain name points to the latest IP. [0004] Howe...
