Method and device for converting iso image into container image

Abstract

The present invention discloses a method for converting an iso image into a container image, relates to the technical field of cloud computing, and solves the technical problem of converting an iso image into a virtual machine container image. The method comprises: creating a kubevirt virtual machine specification template; providing an http file server; after receiving an iso image uploaded by a user, creating a virtual machine; running the virtual machine to generate a virtual machine instance, and entering the system installation step; the user controls the installation of an operating system through vnc; after the installation is completed, a disk.img file is generated; the image in raw format is converted into a qcow2 compressed image through a qemu command; the qcow2 image is converted into a docker image, and a Dockerfile file is generated; a docker image is generated; and the docker image is uploaded to an image warehouse. The present invention also discloses a device for converting an iso image into a container image. The present invention can convert any operating system image that meets the requirements of virtual machine creation into a docker image, and uniformly manage it within the platform, avoiding two sets of image management methods, and reducing maintenance costs.
