Problems solved by technology

[0003] Because the architectures of virtual machines and containers are completely different, existing technologies cannot directly convert virtual machine images into container images that can run directly in containers
Therefore, the applications in the virtual machines need to be migrated one by one, making the migration difficult and costly

Abstract

The invention discloses a method and a device of migration of a virtual machine to a container, and relates to the field of computer technology. The method of migration of the virtual machine to the container includes: acquiring a mirror image file of the virtual machine; parsing the mirror image file of the virtual machine to acquire multiple pieces of construction information of the virtual machine; establishing construction commands, which correspond to all the construction information, according to grammar formats which are of container mirror image construction commands and correspond totypes of the construction information; adopting the construction commands, which correspond to all the construction information, to form a mirror image construction file of the container; and runningthe mirror image construction file of the container to form a mirror image file which is of the container and corresponds to the mirror image file of the virtual machine. The construction informationacquired from the mirror image file of the virtual machine is adopted to form the mirror image construction file of the container according to grammar structures of the mirror image construction file,the mirror image file which has the same environment as an environment of the original virtual machine and is equipped with the same applications can be generated, thus automatic migration of the virtual machine to the container is realized, and migration efficiency is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for migrating a virtual machine to a container. Background technique [0002] Container technology is gradually replacing many virtual machine usage scenarios due to its advantages such as light weight, high performance, and fast start and stop. Therefore, there is a need to migrate the application originally deployed in the virtual machine to the container and ensure that the migration is consistent with the original application. [0003] Because the architectures of virtual machines and containers are completely different, existing technologies cannot directly convert virtual machine images into container images that can run directly in containers. Therefore, the applications in the virtual machines need to be migrated one by one, which makes the migration difficult and expensive.
