Question: Deploying  Docker Swarm shows the following message "latest could not be accessed on a registry to record its digest. Each node will access MyApp:latest independently, possibly leading to different nodes running different versions of the image." Answer: Docker Swarm requires that you publish your Images to the Docker Registry then pull them from there. This message indicates that you have your Images locally and that if you have nodes on different machines, it warns you that those Images on other Machines/Servers might have a different version of the Image running in the Docker Container.
