Dockerfile

# build with
#   docker build -t snana-summary-webserver .
#
# run with
#   docker run -d --name snana-summary -p 8080:8080 snana-summary-webserver
#
# To bind-mount the source directory for testing purposes, after -d:
#    --mount type=bind,source=$PWD,target=/code
#
# For this to work, you need to drop a symbolic link in static:
#   cd static
#   ln -s ../rkwebutil/rkwebutil.js rkwebutil.js
#
# To bind-mount an external data dir, also add:
#    --mount type=bind,source=<datadir>,target=/data \
#
# So the command for both, run from here, might be:
#
#  docker run -d --name snana-summary -p 8080:8080 \
#    --mount type=bind,source=$PWD,target=/code \
#    --mount type=bind,source=$PWD/data,target=/data \
#    snana-summary-webserver
#
# where <datadir> is where the .pkl files exported from
# lib/parse_snana.py live (perhaps $PWD/data).
