Answer 1

You were created an overlay network with Docker Engine swarm mode, which name is "myapp". However, overlay networks for a swarm are not available to containers started with docker run that don't run as part of a swarm mode service.

If you want create a network for your local containers, you should consider to create a local bridge network with the following command:

$ docker network create --driver bridge myapp

You may need to read that Understand Docker container networks document carefully, which explained the difference between bridge network and overlay network very well.
