Description

Sensitive information, such as passwords, keys, and tokens must not be stored in application code. Kubernetes offers a resource called Secrets that are designed for storing sensitive information for use by applications. Secrets are created and managed separately from application code. Additionally, they can be encrypted at rest and access to the secrets can be controlled via RBAC.
