Problems solved by technology

[0003] However, because the Docker image is only the packaging of the application operating environment, it has requirements for the CPU architecture and kernel version of the running host machine. For example, the Docker image running on the AMD64 CPU architecture machine cannot be directly run on the ARM64 CPU architecture. on the machine
Therefore, when starting the application compilation environment, the differences in the underlying hardware facilities cannot be co

Abstract

The invention discloses a method for realizing cross compiling of a Docker mirror image. The method specifically comprises the following steps: S1, installing a qemu-user-static service program on a Docker mirror image cross compiling environment system, s2, checking whether a binfmt _ misc in the Linux system registers a corresponding simulator configuration or not; s3, determining the CPU architecture type of the Docker mirror image needing cross compiling, s4, a Docker file for constructing a Docker mirror image is compiled; docker mirror images of different target CPU frameworks are constructed by using the same Docker file, and the Docker mirror images of different target CPU frameworks are constructed by using the same Docker file. And S5, determining whether the generated Docker mirror image is the mirror image of the target CPU architecture or not by checking the identifier in the generated Docker mirror image. The invention relates to the technical field of computer programs.According to the method for realizing Docker mirror image cross compilation, when the application compilation environment is started, the difference of underlying hardware facilities can be completelyshielded, and the problem of cross-platform cross compilation is solved, so that the problem caused by the difference of underlying hardware can also be shielded while the application cross compilation environment is rapidly started.

Description

technical field [0001] The invention relates to the technical field of computer programs, in particular to a method for realizing cross-compilation of Docker images. Background technique [0002] Docker is currently the most popular Linux container solution, providing an easy-to-use container interface. Docker packages the application program and the program's dependent files into an image file. By running this packaged image file, a virtual container will be generated. The application runs in this virtual container, just like running on a real server. Packaging the runtime environment of the application in this way helps Realize the convenience of application deployment, the flexibility of application test environment construction, and the quickness of cross-platform migration. After the application is packaged into a container image, it can run in any environment, including: physical server, virtual machine, public cloud, private cloud, etc. Due to the characteristics o...
