How to Do a Clean Restart of a Docker Instance
If you are using Docker-Machine, make sure your are talking to the right one. Execute the command docker-machine ls to find which one is currently active. It is also recommended to always redo the command:
eval "$(docker-machine env )"
Note: Deleting volumes will wipe out their data. Back up any data that you need before deleting a container.
Procedure
Stop the container(s) using the following command:

docker-compose down

Delete all containers using the following command:

docker rm -f $(docker ps -a -q)

Delete all volumes using the following command:

docker volume rm $(docker volume ls -q)

Restart the containers using the following command:

docker-compose up -d
