Automated Agent Injection in Container Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to automate the injection of in-process agents into container-isolated processes, as operating system adaptations and resource requirements for agent injection are not visible within containers, limiting performance monitoring capabilities.
Innovation Solution
An operating system agent detects container manager processes and establishes a monitoring connection to manipulate the container environment for automated injection of in-process agents, making necessary resources and libraries accessible within the container, and using kernel space components or behavior analysis to identify and inject agents into processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If container-based virtualization is used to provide isolated execution environments, then resource efficiency and flexibility are improved, but automated agent injection into container processes fails because operating system adaptations and injection resources are not visible inside containers
Solution Approach 1:
The patent introduces a container manager as an intermediary component that bridges the host operating system and container processes. The container manager intercepts process startup requests, modifies them to include agent injection instructions, and ensures agents are injected into container processes despite the isolation boundaries. This mediator approach resolves the contradiction by enabling automated injection without breaking container isolation.
Solution Approach 2:
The patent operates at multiple levels: host operating system level for detecting container creation, container manager level for modifying process startup, and container process level for actual agent injection. By adding the container manager dimension between the host OS and container processes, the system enables automated injection while maintaining container isolation boundaries.
2Reliability
If container isolation is enforced to protect processes, then process security and independence are improved, but visibility of operating system resources and libraries required for agent injection is lost
Solution Approach 1:
The patent performs preliminary actions by modifying container startup configurations before container processes actually start. The container manager pre-configures the container environment with necessary agent libraries and injection resources, ensuring they are available when processes start. This preliminary preparation resolves the resource visibility issue without compromising ongoing isolation.
Solution Approach 2:
The container manager enables containers to self-service by automatically injecting agents into container processes without requiring manual intervention or breaking isolation. The system configures itself to provide necessary resources and perform injections autonomously, maintaining both isolation and ease of operation.
3Measurement precision
If manual agent injection processes are used, then injection control and precision are improved, but automation capability and efficiency deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the container manager monitors container process startup events in real-time and automatically triggers agent injection based on detected process creation. This event-driven feedback loop maintains precise control over injection timing while achieving full automation, resolving the contradiction between precision and efficiency.
Solution Approach 2:
The system achieves automation by enabling self-service injection where the container manager autonomously detects process startups and performs injections without manual intervention. This self-service approach maintains precise control through automated event monitoring while dramatically improving productivity through elimination of manual operations.
Data Source
AI summary
A system and method is presented that installs an agent on a computer system that monitors the start of processes by the computer system and that identifies the start of processes that perform container management activities, like starting and stopping container environments. On start of a container manager process, the agent starts a container manager agent that establishes a monitoring connection to the container manager process. The container manager agent monitors activities performed by the container manager process to detect the start of new container environments by the container manager process. On detection of a container start, the container manager agent manipulates the container configuration in a way that a process type specific in-process agent is automatically injected into processes started inside the container.
