Automatic Container Image Generation from Runtime Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods require application developers to have knowledge of the application's dependent environment and container knowledge to move applications from a host to a container, which is cumbersome and limited to virtual machine to container migrations, lacking efficiency in handling physical machines and requiring full layer data copying.
Innovation Solution
A method to automatically generate a container image by detecting and collecting service runtime information, creating a container based on this information, and updating it as needed, allowing for seamless migration of applications from hosts (both physical and virtual) to containers without requiring specific environment knowledge or full data copying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If application developers manually configure container images with dependent environment knowledge, then container migration accuracy is improved, but developer complexity and time consumption increase
Solution Approach 1:
The system enables automatic container image generation by having the runtime environment itself provide the necessary configuration information. The runtime environment automatically generates container images without requiring developer intervention or manual configuration, thus eliminating the complexity burden on developers while maintaining migration accuracy.
Solution Approach 2:
The system copies runtime environment information automatically into container images. By capturing and replicating the runtime environment state, the system preserves all necessary dependencies and configurations without requiring developers to manually document or configure them, thereby reducing developer complexity while maintaining accuracy.
2Reliability
If full layer data copying is performed during container migration, then data completeness is improved, but migration time and bandwidth consumption increase
Solution Approach 1:
The system extracts only the essential runtime environment information needed for container migration rather than copying all layer data. By identifying and transferring only the critical configuration and dependency information, the system maintains data completeness for migration purposes while significantly reducing the amount of data transferred and migration time required.
Solution Approach 2:
The system changes the approach from copying data at the storage layer to copying information at the configuration layer. By transforming the migration process from data-centric to information-centric, the system achieves data completeness through configuration metadata rather than full data duplication, thereby reducing migration time and bandwidth consumption.
3Ease of operation
If automatic container image generation is implemented, then developer convenience is improved, but system complexity increases
Solution Approach 1:
The runtime environment is designed to serve multiple functions: it executes applications, manages runtime configurations, and automatically generates container images. By making the runtime environment multi-functional, the system eliminates the need for separate complex image generation tools while improving developer convenience through automation.
Solution Approach 2:
The system uses the runtime environment itself to generate container images automatically. The runtime environment leverages its existing capabilities to provide image generation functionality, avoiding the need for additional complex external tools. This self-service approach improves developer convenience while keeping the added system complexity minimal by reusing existing runtime components.

AI summary
Various embodiments are provided for automatically generating a container image by a processor. Service runtime information associated with an operating system (OS) may be detect and collected. The collected service runtime information may be validated. A container having the collected service runtime information may be created. A container image may be generated according to the container. The container image may be updated upon detecting a change to the service runtime information.
