# test that your unbound container is working properly by opening your ssh terminal
# for the pi or server that you are running this on:
#   dig google.com -p 5053 @127.0.0.1 
# you may also change the @ ip address to the physical ip of the server.
# in the event that it times out, follow instructions from above ^


#to find info about container through terminal like IP address and things,
#type docker inspect $CONTAINER_NAME where $CONTAINER_NAME is the name of the 
#container you wish to inspect.

# The $ symbol reflects a wildcard. You can use that wildcard if you wish and just add them as
# your environment variables. Some just like to change the info right on the compose
# so that you don't have to worry about missing the environment variable when you deploy the containers
# i.e. TIMEZONE as the variable name and America/New_York as the value.
