We use the plugin kaniko-ecr to build and push images to ECR. We would like to know the imageDigest of the image that was built and pushed. The value we need is already being written to a file within the plugin execution by using the flag on the kaniko command. Sending that back to us as an output variable would be fantastic. Without it, we have to make a network request to based on the tag to get info about the image it just pushed.
