Production users of containers overwhelmingly think of Docker as a packaging format. Docker the company thinks it is much more. The chart is from a JFrog survey and was completed by many Artifactory users, which means they understand the roles package and repository managers play. Along with Sonatype and others, repo managers are actively positioning their products, along with container registries, as an essential part of continuous development pipelines. The next time you look at a CD workflow diagram, ask yourself if Docker is just another packaging format or if container services are something much more.
