# Sign container images in Signer
<a name="container-workflow"></a>

This section describes procedures for signing container images stored in an Open Container Initiative (OCI) compliant container registry. Before you begin, make sure you have completed the prerequisites listed in [Get started with AWS Signer](getting-started.md).

**Note**  
If you're coming here from the Amazon ECR image signing documentation, be aware that you must fulfill all of the requirements related to Amazon ECR before beginning these AWS Signer procedures. For more information, see [Signing an image](https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-signing.htm) in the *Amazon Elastic Container Registry User Guide*.
