-WGRIB2 on Container (Debian Bulleyes)
-### Note: I update the container based on: https://hub.docker.com/r/bearstudio/wgrib/
-## USAGE
-
-### Build:
-`docker build -t sondngyn/wgrib2 .`
-### On Linux:
-`docker run -v /path/to/data:/srv/ -v /path/to/script:/opt/ sondngyn/wgrib2 /opt/script_file_name.sh`
-### On Windows: 
-*Note:
-Remember to put `#!bin/bash` in the beginning of your script file
-Make sure your script file uses LF (Linux line break types) instead of CRLF (Windows). You can easily change it on VS Code
-`docker run -v C:\absolute\path\to\data\dir\:/srv/ -v C:\absolute\path\to\script\dir\:/opt/ sondngyn/wgrib2 /opt/script_file_name.sh`
-(watch out for back-slashes and forward-slashes)
-### Example on Windows (powershell): 
-`docker run -v C:\Users\myuser\mydata\:/srv/ -v C:\Users\myuser\myscript\:/opt/ sondngyn/wgrib2 /opt/myscript.sh`
-
-## DEV:
-0. Clean up: `docker container rm wgrib2 -f`
-1. Build image: `docker build -t wgrib2 .`
-2. Spin up container: `docker run --rm --name wgrib2 -d -it wgrib2`
-3. Exec: `docker exec -it wgrib2 bash`
