bravo
thanks for this! it works with sys.argv as well
@RheingoldRiver , how did you use it with sys.argv ?
@parikshit14
Pretty much exactly as shown in the original. Here is my dockerfile:
FROM python:3.8.16-bullseye
COPY /requirements.txt /requirements.txt
RUN pip install -U pip
RUN pip install -r requirements.txt
WORKDIR historic-employee-count-tool
COPY . .
ENTRYPOINT [ "python", "historic-employee-count-tool/main.py"]
And in the python code here is how to access an arg:
key_arg = sys.argv[1]Remember with argv, 0 is reserved as the name of the script.
@RheingoldRiver how did you executed it docker run ....what....
@parikshit14
You run it with:
docker run -it container-name-here param1 param2 param3
Here's a link to the full repo including a README in case that's helpful too.
