Host Container Mounting for OS Version Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for container compatibility require container images to include multiple versions of computer-executable instructions or access external repositories, which adds complexity and may result in container failure if compatible versions are not available.
Innovation Solution
A method for mounting a compatible computer-executable instruction from a host virtual machine into a container, allowing the container to execute on any version of the host operating system by detecting incompatibilities and accessing compatible instructions from the host.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If container images include multiple versions of computer-executable instructions, then container compatibility with different host OS versions is improved, but device complexity increases
Solution Approach 1:
The patent extracts the computer-executable instructions from the container image and stores them separately on the host system. The container image only contains the container runtime environment, while the actual executable instructions are retrieved from the host's storage, eliminating the need to include multiple instruction versions in the container image itself.
Solution Approach 2:
The host system acts as an intermediary between the container image and the execution environment. The host stores compatible computer-executable instructions and provides them to the container runtime as needed, mediating the compatibility issue between container images and different host OS versions without requiring the container image to know about multiple instruction versions.
2Adaptability or versatility
If container images access external repositories for compatible instructions, then container compatibility is improved, but reliability decreases due to potential availability issues
Solution Approach 1:
The host system pre-stores compatible computer-executable instructions locally before the container needs to execute. This preliminary action ensures that when the container runtime requires an instruction, it can be immediately retrieved from the host's storage without attempting to access external repositories, eliminating network dependency and improving reliability.
3Ease of operation
If container images include all necessary instructions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent extracts the computer-executable instructions from the container image and stores them separately on the host system. The container image only contains the container runtime environment, while the actual executable instructions are retrieved from the host's storage, eliminating the need to include multiple instruction versions in the container image itself.
Solution Approach 2:
The system segments the container deployment into two separate components: the container image (containing runtime environment) and the host system (storing executable instructions). This segmentation allows each component to be optimized independently - the container image remains lightweight and portable, while the host system provides the necessary instructions locally.

AI summary
The described techniques are directed towards a host virtual machine configured to host a container. In some examples, a system can monitor communication between a container executing on a host virtual machine and the host virtual machine. The host virtual machine can include a first operating system. The container can include a first computer-executable instruction. The system can detect that the first computer-executable instruction is configured to run on a second operating system based on monitoring the communication between the container executing on the host virtual machine and the host virtual machine. The system can further detect a second computer-executable instruction that is configured to run on the first operating system, the second computer-executable instruction can be accessible to the host virtual machine. The system can further include mounting the second computer-executable instruction from the host virtual machine into the container.
