Containerized cross-platform operating system image construction method

Abstract

The invention discloses a containerized cross-platform operating system image construction method. The method comprises the following steps: constructing a guidance description file which comprises software package acquisition mode description, software package dependency relationship description, software package preparation stage description, software package configuration stage description, software package compiling stage description and software package installation stage description; preparing an automatic construction tool; preparing a cross-compilation environment for the target processor architecture; creating a target directory to be prepared for target processor software compilation; preparing a cross compiler shell program; preparing an automatic construction tool shell program; installing a basic C language library in a target directory; and executing an automatic compilation and installation process and software library installation according to the software package description file required by the operating system image. According to the method, a complete operating system image is completely and automatically generated on a platform of a non-target processor by utilizing a cross-platform cross-compiling technology.

Description

technical field [0001] The invention relates to a containerized cross-platform operating system image construction method, which belongs to the technical field of domestic processor operating system platforms. Background technique [0002] The operating system image is composed of boot files and root file systems necessary for the operation of the operating system. It can be a copy file of the hard disk that can boot the operating system. The copy file can be directly booted in the virtual machine or copied to the physical disk. Realize the operating system booting of the physical machine. [0003] The basic operating system image can be increased or decreased in function, and can be large or small in capacity. For example, in embedded operating systems, in order to avoid occupying too much system memory that users urgently need, the operating system image always compresses the space as much as possible, usually based on the busybox commonly used in embedded systems (combin...

Problems solved by technology

[0004] The main disadvantage of existing OS image building methods is the inability to achieve cross-platform generation

Existing server operating system construction methods, such as open-source mainstream Linux distributions Ubuntu, CentOS, or the example project LFS (Linux From Scratch, a Linux From Scratch project) initiated by Linux enthusiasts to build Linux distributions from scratch. The installation method), etc., cannot realize the cross-platform generation of all software packages
