Docker“運行”找不到文件

Question

我正在嘗試從 Docker 容器運行 Python 文件，但收到錯誤：

docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"./models/PriceNotifications.py\": stat ./models/PriceNotifications.py: no such file or directory": unknown.

我使用命令構建和運行：

docker build -t pythonstuff .

docker tag pythonstuff adr/test

docker run -t adr/test

Dockerfile：

FROM ubuntu:16.04

COPY . /models

# add the bash script
ADD install.sh /
# change rights for the script
RUN chmod u+x /install.sh
# run the bash script
RUN /install.sh
# prepend the new path
ENV PATH /root/miniconda3/bin:$PATH

CMD ["./models/PriceNotifications.py"]

安裝.sh：

apt-get update  # updates the package index cache
apt-get upgrade -y  # updates packages
# installs system tools
apt-get install -y bzip2 gcc git  # system tools
apt-get install -y htop screen vim wget  # system tools
apt-get upgrade -y bash  # upgrades bash if necessary
apt-get clean  # cleans up the package index cache

# INSTALL MINICONDA
# downloads Miniconda
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O Miniconda.sh
bash Miniconda.sh -b  # installs it
rm -rf Miniconda.sh  # removes the installer
export PATH="/root/miniconda3/bin:$PATH"  # prepends the new path

# INSTALL PYTHON LIBRARIES
conda install -y pandas  # installs pandas
conda install -y ipython  # installs IPython shell

# CUSTOMIZATION
cd /root/
wget http://hilpisch.com/.vimrc  # Vim configuration

我嘗試將 Dockerfile 中的 CMD 修改為：

CMD ["/models/PriceNotifications.py"]

但同樣的錯誤發生。

文件結構如下：

我應該如何修改 Dockerfile 或 dir 結構，以便找到並執行models/PriceNotifications.py ？

Answer 1

感謝之前的評論，使用路徑：

CMD ["/models/models/PriceNotifications.py"]

代替

CMD ["./models/PriceNotifications.py"]

允許 Python 腳本運行。

I would have thought CMD ["python /models/models/PriceNotifications.py"] should be used instead of CMD ["/models/models/PriceNotifications.py"] to invoke the Python interpreter but the interpreter seems to be already available as Docker 運行的一部分。
