Container Image Isolation via User-Specific Databases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container management systems fail to implement user-level isolation of data, leading to security issues as users can inadvertently access and provision container images belonging to other users, resulting in potential data leakage.
Innovation Solution
A container management method that utilizes a user-specific container image information database to ensure that only the user's container images are queried and provisioned, preventing access to images belonging to other users by using a mapping relationship between user identifiers and container images, and employing authentication to further secure the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shared storage space is used to store container images for multiple users, then resource utilization is improved, but data security deteriorates due to potential unauthorized access to other users' container images
Solution Approach 1:
The patent segments the storage system by creating separate container image information databases for each user, identified by unique user identifiers. Each database contains only the container images belonging to that specific user, physically isolating user data at the database level while maintaining a unified storage infrastructure
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that mediates between users and the storage system. When a user requests container images, the system authenticates the user's identity and permissions before allowing access, ensuring that users can only retrieve images from their own database while still enabling resource sharing through controlled access
2Reliability
If user authentication is implemented to secure container image access, then data security is improved, but system complexity increases due to additional authentication mechanisms
Solution Approach 1:
The patent implements preliminary authentication actions by verifying user identities and permissions before allowing access to container images. The system checks whether the requesting user has authorization to access specific images based on pre-configured user rights, establishing security controls in advance rather than reacting to potential breaches
Solution Approach 2:
The patent employs a universal authentication mechanism that handles multiple security scenarios through a single framework. The same authentication system manages both read access to container images and write access for uploading new images, as well as enforcing isolation between different user databases, reducing overall system complexity through consolidation
Data Source
AI summary
This application discloses a container management method, apparatus, and device. The method includes: obtaining a provisioning request that carries an identifier of a first user and an identifier of a first container image; querying and obtaining the identifier of the first container image in a container image information database of the first user; obtaining the container image based on the identifier of the first container image; and provisioning a container based on the container image.
