Control Node Remote Configuration Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automation frameworks, such as Ansible, require manual intervention by system administrators to download and import updated configuration files at control nodes, which is time-consuming and resource-intensive.
Innovation Solution
Implementing a mechanism for control nodes to automatically retrieve and execute remote configuration files, analyzing the files to detect associated resources, and generating an executable version in memory, thereby eliminating the need for local storage and manual updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to download and import updated configuration files at control nodes, then configuration files can be updated, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The control node automatically retrieves and executes updated configuration files from remote locations without requiring manual intervention. The system self-updates by detecting changes in remote configuration files, downloading them, and importing them automatically, thereby eliminating the time-consuming manual update process while ensuring reliable configuration updates.
Solution Approach 2:
The control node continuously monitors remote configuration files for updates before they are needed. By detecting changes in advance and automatically retrieving updated files, the system prepares configuration updates in advance, eliminating the need for manual intervention when updates are required and reducing overall update time.
2Ease of operation
If local copies of configuration files are stored at control nodes, then configuration files are accessible, but storage resources are consumed and manual management is required
Solution Approach 1:
The system extracts the configuration file storage function from the control node's local storage. Instead of maintaining local copies of configuration files, the control node retrieves files on-demand from remote locations. This eliminates the need for local storage of configuration files while maintaining accessibility, thereby freeing up storage resources.
Solution Approach 2:
The control node acts as an intermediary between the remote configuration file storage and the execution environment. It temporarily holds configuration files in memory during execution rather than storing them permanently on disk. This intermediary approach maintains file accessibility during operations while minimizing storage resource consumption.
3Reliability
If configuration files are manually downloaded and imported, then updates can be applied, but administrative burden increases
Solution Approach 1:
The control node automatically detects changes in remote configuration files, retrieves updated versions, and imports them without requiring administrative intervention. The system self-manages configuration updates by monitoring for changes, downloading updated files, and applying them automatically, thereby reducing administrative workload while ensuring reliable updates.
Solution Approach 2:
The control node continuously monitors remote configuration files for changes and automatically responds by retrieving and importing updates when changes are detected. This feedback mechanism ensures that configuration files are always up-to-date without requiring manual checking or administration, thereby reducing administrative burden while maintaining update reliability.
Data Source
AI summary
Control nodes can execute configuration files from remote locations according to some examples described herein. For example, a control node may receive an input indicating a remote location, which can include configuration files. In response to receiving the input, the control node may retrieve a configuration file from the remote location. The configuration file can be used by the control node to deploy a software entity at one or more nodes. The control node may analyze the configuration file to detect one or more references indicating one or more resources associated with the configuration file. The control node can then generate an executable version of the configuration file by retrieving each of the resources. The control node can further execute the executable version of the configuration file to deploy the software entity at each of the nodes.
