Secrets

Secrets in Kubernetes are used to securely store sensitive data such as passwords, API keys, tokens, and certificates. They help manage confidential information by keeping it separate from application code and configuration, ensuring secure access and preventing accidental exposure. Secrets are encoded and mounted as files, environment variables, or accessed programmatically.

Because Secrets can be created independently of the Pods that use them, there is less risk of the Secret (and its data) being exposed during the workflow of creating, viewing, and editing Pods. Kubernetes, and applications that run in your cluster, can also take additional precautions with Secrets, such as avoiding writing sensitive data to nonvolatile storage.
