How do I sign and verify images for Service discovery?

In modern cloud-native applications, ensuring the integrity and authenticity of container images is crucial for secure service discovery. Signing images helps verify that the images come from trusted sources and have not been tampered with.

To sign and verify images, you can use tools like Docker Content Trust (DCT) and Notary. Here's a brief explanation of how to sign and verify Docker images.

export DOCKER_CONTENT_TRUST=1 docker build -t my-image:latest . docker push my-image:latest docker trust inspect --pretty my-image:latest

By enabling Docker Content Trust, you ensure that all images pushed to your repository are signed. This signing mechanism provides a layer of security during the service discovery process, allowing you to ensure that only validated images are used in your deployments.
