In this guest post for the Giant Swarm blog, I show how to integrate AWS Secrets Manager with Kubernetes using the External Secrets Operator (ESO), so sensitive values live in a dedicated secrets service instead of directly in Kubernetes Secret objects.
Key takeaways
- ESO bridges Kubernetes and external secret stores, handling authentication and keeping secrets in sync.
- The setup is an IAM user, a ClusterSecretStore for AWS access, and ExternalSecret resources describing what to fetch.
- Apps keep consuming ordinary Kubernetes Secrets, so no code changes are needed.
- The same pattern works with HashiCorp Vault, Google Secret Manager and Azure Key Vault.
