Rich McWilliams thanks for pointing it out. The default value for mount type is ‘volume’ and that worked fine during our tests. Docker swarm mode documentation advises against ‘bind’ mounts [1], so it looks it’s better to avoid it. Intriguing that you had issues with it, would be great if you could describe the problem in more detail.
