I have since discovered that I am not the only one who has experienced this issue and it is interesting to note that it’s been an issue for at least a year and there is no indication of a solution.
I’m also curious why the getting started tutorial uses an experimental feature?
$ docker deploy --help
docker deploy is only supported on a Docker daemon with experimental features enabled
Perhaps I should leave the tutorial there and come back to it later. I have enough to create and use containers on one machine which is enough for my needs right now.
