Is it possible to add some signature when the docker image is built so that when the image is consumed from docker hub, we can verify the image to ensure it is the image built by elastic team and then use it in our system?
https://hub.docker.com/r/elastic/eck-operator-ubi/tags

or incase the image is already signed, do inform on how we can do the verification, DCT (docker content trust) was tried by our dev ops team member, but nothing was found.
