# AWS::Batch::JobDefinition Secret
<a name="aws-properties-batch-jobdefinition-secret"></a>

An object that represents the secret to expose to your container. Secrets can be exposed to a container in the following ways:
+ To inject sensitive data into your containers as environment variables, use the `secrets` container definition parameter.
+ To reference sensitive information in the log configuration of a container, use the `secretOptions` container definition parameter.

For more information, see [Specifying sensitive data](https://docs.aws.amazon.com/batch/latest/userguide/specifying-sensitive-data.html) in the *AWS Batch User Guide*.
