Automated secret rotation is essential to prevent catastrophic security breaches in modern cloud-native applications.
HashiCorp Vault and Kubernetes are used to implement secure, zero-downtime secret rotation in Spring Boot microservices.
HashiCorp Vault solves the problem of static secrets by generating dynamic secrets, enabling automatic rotation, and managing their expiration.
The implementation involves deploying Vault in Kubernetes, configuring a secrets engine, integrating with Spring Boot, and automating secret rotation with Kubernetes CronJob.
