Actualy, you can use the service template variable '{{.Node.Hostname}}' to render the host name into an environment variable und levarage it within your application.

A while ago, I posted examples of swarm service template variables in the docker forum: https://forums.docker.com/t/example-usage-of-docker-swarm-template-placeholders/73859
