Kubernetes Software Component Lifecycle Management via a Universal Operator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Life-Cycle Management (LCM) systems for large Kubernetes software systems are complex and require excessive manual workflow sets due to the involvement of multiple vendors, making deployment, upgrade, and reconfiguration processes time-consuming and inefficient.
Innovation Solution
A universal operator that dynamically computes and executes workflows based on the current and desired states of the system, using Kubernetes Custom Resources (CRs) to manage software components, including Function, Blend, Layout, and Settings descriptors, enabling automated deployment, upgrade, and reconfiguration without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual workflow sets are used to manage software deployment and reconfiguration in large Kubernetes systems, then each operation can be precisely controlled, but the complexity of the system increases significantly and the process becomes time-consuming
Solution Approach 1:
The patent implements a universal operator framework that can handle multiple software operations (deployment, reconfiguration, upgrades, removal) through a single unified system. The operator uses standardized CRD definitions and workflow templates that can be applied across different software components and vendors, eliminating the need for separate manual workflow sets for each operation type while maintaining precise control through the standardized interface.
Solution Approach 2:
The system enables automated self-service operations where the universal operator automatically computes and executes workflows based on CRD definitions without requiring manual intervention. The operator can independently manage the complete software lifecycle including deployment, reconfiguration, upgrades, and removal by processing CRD changes and executing corresponding workflow templates automatically.
2Adaptability or versatility
If multiple vendor-specific workflow sets are created for large software systems, then each vendor's requirements can be met, but the number of workflows grows exponentially and manual management becomes inefficient
Solution Approach 1:
The universal operator framework provides a single standardized interface that can accommodate multiple vendors' requirements through configurable workflow templates. Instead of creating separate vendor-specific workflow sets, the system uses a universal CRD definition structure that can represent different vendor requirements, with the operator automatically selecting and configuring the appropriate workflow templates based on the software component being managed.
Solution Approach 2:
The patent segments the workflow management into modular workflow templates that can be independently configured and combined. Each vendor-specific requirement is represented as a separate workflow template that can be selected and executed by the universal operator, allowing the system to handle multiple vendors without creating a monolithic complex workflow set. The segmentation enables efficient management by allowing the operator to compose workflows from reusable template components.
3Productivity
If automated workflows are implemented without human intervention, then deployment speed increases, but the initial setup and configuration becomes more complex
Solution Approach 1:
The system performs preliminary configuration by defining standardized CRD structures and workflow templates in advance. The CRD definitions establish the schema and validation rules beforehand, and the workflow templates pre-configure the automation logic for common operations. This preliminary setup enables fast automated execution without human intervention during deployment, while the complexity is front-loaded during the initial configuration phase rather than during each deployment operation.

AI summary
A Life-cycle Component Management (LCM) system associated with Kubernetes can employ a universal operator to aid in the management of any software system, no matter the size or complexity. Specifically, the LCM system includes a universal operator, which eliminates the need for a human software developer to implement a set of workflows. The universal operator dynamically computes and runs the disclosed workflow set, based upon the description of the current state of the system (i.e., the “begin state”) and the new desired state of the system (i.e., the “end state”). Thereby, this universal model enables LCM for large Kubernetes software systems, which require excessive workflow sets due to the intrinsic complexity of large software systems and the plurality of vendors that contribute to such systems.
