SFTP Integration for Containerized Applications

1 post · May 2023

What this trail covers

This post introduces a method to enable SFTP integration for containerized applications, allowing legacy applications that rely on SFTP to be migrated to cloud-native environments like Kubernetes. It explores three solutions for managing SSH private keys: external vaults (AWS Secrets Manager), Kubernetes Secrets, and packaging keys within the container image, recommending the external vault approach for better security and key rotation management. The solution is demonstrated using Amazon EKS and Red Hat OpenShift on AWS (ROSA).

  1. Enable SFTP integration for containerized appsThis post details the implementation of SFTP integration for containerized applications, specifically focusing on migrating legacy applications to cloud-native environments like Kubernetes. It presents three solutions for managing SSH private keys: external vaults (AWS Secrets Manager), Kubernetes Secrets, and packaging keys within the container image. The post recommends the external vault approach for enhanced security and key rotation management, demonstrating the solution using Amazon EKS and Red Hat OpenShift on AWS (ROSA). It also discusses considerations such as using private resources, auto-scaling node groups, security context constraints on OpenShift, alternative deployment patterns, key rotation best practices, logging and monitoring, and finer-grained scheduling intervals.
