    simplyadrian/allsalt:debian_master_2017.7.2
docker exec -it dev-salt-master bash

docker run --rm -d \
    -v $(pwd)/minion.d:/etc/salt/minion.d \
    -h dev-ubuntu-minion \
    --name dev-ubuntu-minion \
    simplyadrian/allsalt:ubuntu_minion_2017.7.2
docker exec -it dev-ubuntu-minion bash

Setup beacon watch file

From the minion, create a file named /etc/important_file and add some simple content:

echo "important_config: True" > /etc/important_file

Edit /etc/important_file:

vi /etc/important_file
# edit it and save
