How are Kubernetes secrets stored inside a container?

How does Kubernetes store secrets?

When you create a Secret with kubectl create -f secret. yaml , Kubernetes stores it in etcd. The Secrets are stored in clear in etcd unless you define an encryption provider. When you define the provider, before the Secret is stored in etcd and after the values are submitted to the API, the Secrets are encrypted.

How are Kubernetes secrets encrypted?

Kubernetes offers envelope encryption of Secrets with a KMS provider, meaning that a local key, commonly called a data encryption key (DEK), is used to encrypt the Secrets. The DEK itself is encrypted with another key called the key encryption key (KEK). The KEK is not stored by Kubernetes.
