This document contains the slides from a presentation about using JFrog Artifactory and Docker. It discusses how Artifactory can be used to manage Docker images across different environments like development, testing, staging and production. It also talks about building applications in layers using base images and promoting images through a pipeline. Key points are that Artifactory allows hosting multiple Docker repositories per host, using tags to promote images, and building applications in layers on top of base images for improved quality and speed.
