From inside one of the container (e.g. the second one) I need to code something (using a bash initialization script) which is able to retrieve the symbolic/pretty name (e.g. “web.2”).
In other words: is there something (some kind of DNS alias or other) that permits to each container to discover by itself (without using the Docker demon) which is the “pretty” name uniquely assigned to it by swarm ?
