Process Control Manager for Container Operator Fault Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container management platforms, such as Kubernetes, face challenges in managing Operators and their associated Controller processes, leading to unrecoverable state scenarios and difficulties in determining the root cause of failures.
Innovation Solution
The introduction of a system-level Process Control Manager (PCM) within the Operator Deployment enables each Operator Controller to run independently as a separate process, with a graceful shutdown mechanism and a new status approach to reflect the overall status of all Operator Controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If multiple Operator Controllers are executed within a single Operator container, then resource utilization is improved, but system reliability deteriorates due to unrecoverable state scenarios and difficulty in determining root cause of failures
Solution Approach 1:
The patent divides the Operator container execution into multiple isolated Operator runtimes, where each Operator Controller executes in its own separate runtime environment. This segmentation allows each controller to be independently managed and recovered, preventing failure propagation while maintaining resource efficiency. The Process Control Manager orchestrates multiple runtimes within a single container, achieving both resource utilization and reliability goals.
2Reliability
If Operator Controllers are run in separate processes, then fault isolation is improved, but device complexity increases due to the need for Process Control Manager and multiple runtimes
Solution Approach 1:
The Process Control Manager serves multiple functions: it creates and manages Operator runtime environments, executes Operator Controllers, monitors their status, and handles failure recovery. By consolidating these diverse functions into a single manager component, the patent reduces overall system complexity while achieving fault isolation through separate process execution.
3Ease of operation
If a single process manages all Operator Controllers, then ease of operation is maintained, but measurement precision deteriorates due to inability to determine root cause of failures
Solution Approach 1:
The patent implements a status reporting mechanism where each Operator Controller executed in separate runtimes reports its health status and execution state to the Process Control Manager. This feedback loop enables precise identification of which specific controller is failing and why, while the unified manager interface maintains ease of operation. The system provides detailed failure diagnostics without requiring complex manual investigation.

AI summary
Mechanisms are provided, in a data processing system specifically configured to implement a computer container management platform in which Operators and Operator Controllers are used to manage at least one custom resource associated with a containerized application, to receive an Operator Deployment comprising an Operator Container having an Operator with a plurality of Operator Controllers. A process control manager (PCM) process configures each Operator Controller to execute as a separate process from each of the other Operator Controllers of the Operator Container. The Operator of the Operator Container is run at least by executing the Operator Controllers of the Operator in separate Operator runtimes based on the configuring of the Operator Controllers.
