Container Configuration Agent for Cloud Application Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Container-based virtualization limits application deployment flexibility due to the requirement that each guest must use the same operating system as the host, and synchronization of configurations for applications running in containers is not efficiently managed, especially in cloud environments.
Innovation Solution
A method and system for configuring applications within containers that involves deploying a container engine and a configuration agent on a machine, where containers send configuration requests to the agent for user-specific information, and plugins within the containers communicate to receive and apply configuration settings, with the agent optionally accessing a server or local database for updates.

Engineering Contradiction Analysis
1Productivity
If container-based virtualization is used to improve deployment efficiency and performance, then application deployment speed and resource utilization are improved, but configuration synchronization across containers becomes complex and difficult to manage
Solution Approach 1:
The patent introduces a configuration management system that acts as an intermediary between containers and configuration sources. This system includes configuration agents deployed on machines that receive containers, configuration plugins within containers that communicate with agents, and configuration servers that store and distribute configuration information. This intermediary layer automates configuration synchronization, eliminating manual management complexity while maintaining fast deployment speeds.
Solution Approach 2:
The system performs preliminary configuration actions by pre-fetching and caching configuration information locally on machines before containers are fully deployed or activated. When a container is received, the configuration agent proactively retrieves configuration data from servers or databases in advance, so that when the container needs configuration, it is already available locally, enabling rapid automated configuration without manual intervention.
2Quantity of substance
If containers are set up in just-in-time mode to improve resource utilization, then resource efficiency is improved, but configuration initialization time increases
Solution Approach 1:
The configuration system performs preliminary actions by pre-fetching configuration information from remote servers and caching it locally on machines before containers are activated. When a container is deployed in just-in-time mode, the configuration agent already has the configuration data available locally, enabling immediate configuration without network delays. This preliminary caching action reduces initialization time while maintaining efficient resource utilization.
Solution Approach 2:
The patent merges the configuration retrieval and container deployment processes by having the configuration agent integrated on the same machine that receives and manages containers. The agent combines local caching capabilities with remote server communication, merging multiple configuration sources into a unified configuration delivery mechanism that operates seamlessly during just-in-time container deployment.
3Speed
If configuration information is stored locally on machines to reduce access time, then configuration access speed is improved, but data synchronization and update management become more difficult
Solution Approach 1:
The configuration agent implements feedback mechanisms by periodically checking for configuration updates from remote servers and comparing them with locally cached configuration data. When updates are detected, the agent automatically retrieves and applies them. This feedback loop ensures local configurations remain synchronized with central servers, maintaining fast local access speeds while automatically managing data synchronization without manual intervention.
4Stability of the object's composition
If a centralized configuration server is used to manage all configuration information, then configuration control and consistency are improved, but network dependency and access latency increase
Solution Approach 1:
The patent adds a spatial dimension to configuration storage by implementing a hierarchical configuration architecture. Configuration information exists in multiple dimensions: centrally on remote servers for master control and consistency, and locally cached on individual machines for fast access. This multi-dimensional storage approach allows the system to simultaneously achieve configuration consistency through centralized management and fast access through local caching, eliminating the trade-off between these two requirements.
Data Source
AI summary
An application executing in a containerized environment may be configured at started up by deploying a configuration agent to execute in a container engine. For each container deployed, instantiating a user configuration plugin and one or more applications to execute in the container. The user configuration plugin may send a request to the configuration agent to request for configuration information relating to the application. The configuration plugin may receive configuration information from the configuration agent and used the received configuration information to configure the application.
