Enable SFTP integration for containerized apps

What this post added

This post details how to containerize an application that requires SFTP integration, specifically addressing the challenge of migrating legacy applications from on-premises to AWS. It outlines three methods for handling SSH private keys: using AWS Secrets Manager, Kubernetes Secrets, or embedding keys in the container image. The post provides a step-by-step guide for implementing the AWS Secrets Manager approach with Amazon EKS and a CronJob, including container image creation, key management, service account configuration, and CronJob deployment. It also discusses other considerations such as using private resources, auto-scaling, security context constraints in OpenShift, and alternative B2B integration methods.
