How do I sign and verify images for Grafana dashboards?

To sign and verify images for Grafana dashboards, you can use the Notary service, which is a part of the Docker Content Trust. Below is a brief guide on how to accomplish this with examples.

Signing an Image

First, ensure Docker Content Trust is enabled by setting the DOCKER_CONTENT_TRUST environment variable to true. Then, you can sign the Grafana image using the following command:

export DOCKER_CONTENT_TRUST=true docker push your-repo/grafana:tag

Verifying an Image

To verify that the image is signed correctly, you can use the docker trust inspect command:

docker trust inspect --pretty your-repo/grafana:tag

It will display the signature information for the image. Ensure that the signatures are valid before deploying the image to your production environments.
