Dockerfile

# To build the DJuno image, just run:
# > docker build -t bdjuno .
#
# In order to work properly, this Docker container needs to have a volume that:
# - as source points to a directory which contains a config.yaml file
# - as destination it points to the /home folder
#
# Simple usage with a mounted data directory (considering ~/.bdjuno/config as the configuration folder):
# > docker run -it -v ~/.bdjuno/config:/home djuno djuno parse
#
# If you want to run this container as a daemon, you can do so by executing
# > docker run -td -v ~/.bdjuno/config:/home --name bdjuno bdjuno
#
# Once you have done so, you can enter the container shell by executing
# > docker exec -it bdjuno bash
#
# To exit the bash, just execute
# > exit
