Secret

Secrets are used to securely store confidential data such as passwords, OAuth tokens, and SSH keys in a Kubernetes cluster. By utilizing Secrets, you can exercise more control over how sensitive data is used and minimize the risk of accidental disclosure. By default, Secret values are encoded as base64 strings and stored unencrypted, but it's possible to configure Secrets to be encrypted when at rest. Pods can reference a Secret in various ways, including as an environment variable or a volume mount. It's worth noting that Secrets are intended for confidential data, while ConfigMaps are better suited for non-confidential data.
