Abstract

The application relates to a container persistent-storage mounting method, and belongs to the technical field of computers. The method includes: receiving a container creation request, wherein the container creation request includes a container identifier of a to-be-created container; reading a pre-stored configuration file according to the container creation request, wherein the configuration file includes a volume directory address and a mapping address of mapping a volume into the to-be-created container; establishing a binding relationship among the container identifier, the volume directory address and the mapping address; and creating the container with the container identifier, wherein data provided by the container synchronously change with data, which are indicated by the volume directory address, through the binding relationship. The persistence storage problem of partial data in container instances can be solved, and an effect that the data in the container can be saved intoa local file system is realized.

Description

technical field [0001] The invention relates to a container persistent storage mounting method, which belongs to the technical field of computers. Background technique [0002] To implement copy-on-write, containers use a feature called an overlay file system. That is, when the root image needs to be modified, the container will use this feature to write the changed content to the independent area and "overwrite" the original content. Such modifications are usually transient, that is, typically, when the container is deleted, the modifications are no longer present. Therefore, containers have no persistent storage by default. [0003] To solve the storage problem, tools like Docker provide new features for more persistent storage: Docker volumes and data containers. [0004] But because Docker uses local storage, Cinder shared storage is not supported. Contents of the invention [0005] The purpose of the present invention is to provide a technical solution that can sa...
