AI Technical Summary

Technical Problem

In enterprise-level cloud-native infrastructure, existing technical solutions suffer from problems such as high key distribution complexity, conflict between dynamic networks and resident processes, and security vulnerabilities such as unauthorized access by multi-tenants, making it difficult to achieve passwordless data transmission across cluster containers.

Method used

A centralized, passwordless data transfer method for cross-cluster containers is adopted. This method dynamically creates temporary visitor containers (sandbox environments) in the target business cluster and mounts the target data volume in these containers to achieve cross-cluster data transfer. The temporary containers are destroyed immediately upon completion of the transfer. The centrally managed cluster is used for key management and authentication to avoid manual operation.

Benefits of technology

It achieves physical isolation and access security for cross-cluster container data transmission, reduces key distribution complexity, reduces operation and maintenance costs, and completely eliminates security vulnerabilities such as unauthorized access in a multi-tenant environment.

Abstract

This invention discloses a method and system for passwordless data transmission across cluster containers based on centralized management. The method is executed on a stateless SSH proxy server in the target business cluster and includes: intercepting a passwordless connection request sent by a source client to the target business cluster from a source container instance in the source business cluster, based on the source client's private key; requesting authentication of the passwordless connection request from the central management cluster; if authentication is successful, requesting the container orchestration configuration file of the target business cluster from the central management cluster; dynamically creating a temporary visitor container in the target business cluster and mounting the corresponding target data volume according to the container orchestration configuration file, so that the source container instance can read and write data from the target data volume mounted on the temporary visitor container; and destroying the temporary visitor container and releasing the target data volume in response to a passwordless connection termination request from the source container instance. This invention achieves physical isolation and access security for cross-cluster container data transmission.
