A file pulling or pushing method and device based on a distributed container

Abstract

The invention discloses a file pulling or pushing method based on a distributed container. The method comprises: specifying file paths and file names of to-be-pulled or pushed files in the distributedcontainers and storage positions of the pulled or pushed files are specified; Recording the custom name of each distributed container and the URL of the host where the distributed container is located to form a configuration file of each distributed container; Traversing a host corresponding to the recorded URL on the configuration file to remotely connect with a corresponding host, and generating a corresponding container client instance; And according to the file path and the file name of the to-be-pulled or pushed file in each distributed container and the storage position of the pulled orpushed file, copying the file through the container client instance. The invention further discloses a corresponding file pulling or pushing device based on the distributed container. The method andthe device have the beneficial effect that file copying and moving among a plurality of distributed containers can be realized conveniently and quickly.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for pulling or pushing files based on a distributed container (Container). Background technique [0002] Operating system virtualization simulates real computer hardware devices, so that multiple users can share and use computer hardware resources through the virtualized operating system, so that computer hardware resources can be used efficiently. At the same time, due to the virtualization of the operating system, various applications and their dependencies are isolated, so that each user operates an independent operating system on a personal computer. [0003] For example, as a typical example of operating system virtualization, a virtual machine usually runs on a host device of underlying hardware such as a server, and computer hardware resources such as memory and CPU are allocated to multiple virtual machines through a hypervisor. Therefore, it can be a...

Problems solved by technology

Since the current acquisition and distribution of distributed files are basically non-container-related, that is, there are no very useful tools based on file copying inside and outside the container; therefore, under distributed services, whether it is centralized data in different machine containers or Distributing data is cumbersome and difficult

The container's native copy command (docker cp) can only realize internal and external operations between local containers, and it is difficult to realize file operations between containers of multiple distributed machines
