When using COPY with more than one source file, the destination must be a directory and end with a /

[ktfcaptain]

I have this running on Proxmox now but was erroring out trying to COPY pyproject.toml & peotry.lock until the line was ended with a forward slash(as it's shown with said comment bellow).

I can barely copy/paste half the time, definitely no expert, but thought I'd share.

• Dockerfile:

RUN apk add --no-cache build-base libffi-dev
RUN pip install poetry

WORKDIR /mnt
COPY pyproject.toml poetry.lock ./  # Ensure the destination ends with a forward slash
RUN poetry install --no-root --only main

COPY . .
ENTRYPOINT ["poetry", "run", "python", "discollama.py"]
