2. generate and save the alerts file to disk (in the DATADIR folder)

Usage in production mode

STEP 1 - Clone the repository in your server using git

git clone https://github.com/ITHACA-org/aux-accumul.git

STEP 2 - Customize the procedure

1. copy the sea/land mask file and the rain-threshold files in the tool_data folder
2. edit the config.ini file with proper values

docker build --tag tag_name:version .

You should now have a docker image with that <tag_name>.

STEP 4 - Run the image for the first time with the following command

docker run -it --volume /path/to/host/data/folder:/home/aux-accumul/data/wrf --name container_name tag_name:version
