如何在Dockerfile中向PYTHONPATH添加路径 [英] How do you add a path to PYTHONPATH in a Dockerfile

问题描述

如何在Dockerfile中向PYTHONPATH添加路径?这样，当容器运行时，它具有正确的PYTHONPATH吗?我是docker的新手.

How do you add a path to PYTHONPATH in a Dockerfile? So that when the container is run it has the correct PYTHONPATH? I'm completly new to docker.

我已经将ENV PYTHONPATH "${PYTONPATH}:/control"添加到了Dockerfile中，因为我想将目录/control添加到PYTHONPATH中.

I've added ENV PYTHONPATH "${PYTONPATH}:/control" to the Dockerfile as I want to add the directory /control to PYTHONPATH.

当我使用docker exec -it trusting_spence bash访问容器bash并打开python并运行目录control下的命令时，不在列表中.

When I access the containers bash with docker exec -it trusting_spence bash and open python and run the commands below the directory control is not on the list.

import sys print(sys.path)

import sys print(sys.path)

FROM python:2
RUN pip install requests\
&& pip install pymongo

RUN mkdir control

COPY control_file/ /control

ENV PYTHONPATH "${PYTONPATH}:/control"

CMD ["python","control/control_file/job.py"] 

推荐答案

只需在Dockerfile中添加ENV条目:

ENV PYTHONPATH "${PYTHONPATH}:/your/custom/path"

或在启动脚本中设置PYTHONPATH.
