Dockerfile

# 1. The Qniapp is built as follows:
#   $ git clone https://github.com/qniapp/qni.git
#   $ cd qni
#   $ docker build -f Dockerfile . -t qni_server
# 2. Then run by:
#   $ docker run -p 3000:3000 --rm -it qni_server
# 3. access http://127.0.0.1:3000 in your browser

# Troubleshooting
#   If the port 3000 is already used, change 3000 to 4000 (for example)
#    $ docker run -p 4000:3000 --rm -it qni_server
#   and access http://127.0.0.1:4000 in your browser
