Container Clustering via DNS Discovery and Self-Service Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container clustering solutions require manual intervention for discovery, configuration, and re-configuration, making the process time-consuming, complex, and expensive.
Innovation Solution
A container cluster component is implemented within a container-based architecture that automates the discovery, configuration, and re-configuration of containers by using a domain name server query to identify other containers and configure them without manual intervention, employing a master application image to execute these functions.

Engineering Contradiction Analysis
1Productivity
If manual intervention is used for container discovery, configuration, and re-configuration, then configuration accuracy can be ensured, but the process becomes time-consuming and complex
Solution Approach 1:
The container cluster component automatically performs discovery, configuration, and re-configuration operations without requiring manual intervention. The system uses DNS queries to self-identify other containers and automatically configures cluster membership, enabling the system to serve itself rather than requiring external manual configuration for each operation.
Solution Approach 2:
The system pre-configures a master application image that contains the container cluster component with built-in automation logic. This preliminary preparation of the container image with embedded clustering functionality allows subsequent clustering operations to execute automatically without ad-hoc manual configuration steps.
2Manufacturing precision
If manual configuration is performed for each container, then configuration precision can be maintained, but the time required increases significantly
Solution Approach 1:
The container cluster component continuously monitors container state changes and automatically triggers re-configuration operations when changes are detected. This feedback mechanism ensures that the cluster configuration remains accurate and synchronized with the actual container deployment state without requiring manual verification or adjustment.
Solution Approach 2:
When container state changes are detected, the system automatically performs re-configuration operations without requiring manual intervention. The container cluster component self-manages the entire re-configuration process, maintaining configuration accuracy while eliminating the time loss associated with manual reconfiguration steps.
3Ease of operation
If automated DNS-based discovery is used, then the clustering process becomes faster and simpler, but manual configuration control is reduced
Solution Approach 1:
The system introduces a container cluster component as an intermediary layer between the container runtime environment and the clustering configuration. This intermediary automatically manages DNS-based discovery and configuration operations, providing full automation while maintaining the ability to intervene manually if needed, thus achieving both ease of operation and appropriate automation levels.

AI summary
Implementations provide for container clustering in a container-based architecture. A method of the disclosure includes generating by a processing device executing a container deploying an instance of an application image, a domain name server (DNS) query to request identification of other containers in a container cluster. The other containers deploy other instances of the application image. The method also includes in responsive to the DNS query, receiving the identification of each of the other containers in the container cluster. The method further includes configuring, without manual intervention, the container as a member of the container cluster in view of the identification of each of the other containers.
