python – Docker：如何获取virtualenv并安装requirements.txt？

2023年3月11日 255次阅读

我不确定我在这里缺少什么. canonicaliser_api包含我的代码和requirements.txt.

FROM ubuntu:14.04.2
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
RUN apt-get -y update && apt-get upgrade -y
RUN apt-get install python build-essential python-dev python-pip python-setuptools -y
RUN apt-get install libxml2-dev libxslt1-dev python-dev -y
RUN apt-get install libpq-dev postgresql-common postgresql-client -y
RUN apt-get install openssl openssl-blacklist openssl-blacklist-extra -y
RUN apt-get install nginx -y
RUN pip install virtualenv uwsgi

ADD canonicaliser_api /home/ubuntu
RUN virtualenv /home/ubuntu/canonicaliser_api/venv
RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && pip install -r /home/ubuntu/canonicaliser_api/requirements.txt

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80

CMD service nginx start

当我尝试构建它时,一切都很好,直到第11步：

Step 11 : RUN source /home/ubuntu/canonicaliser_api/venv/bin/activate && pip install -r /home/ubuntu/canonicaliser_api/requirements.txt

This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning.
  InsecurePlatformWarning
Could not open requirements file: [Errno 2] No such file or directory: '/home/ubuntu/canonicaliser_api/requirements.txt'
The command '/bin/sh -c source /home/ubuntu/canonicaliser_api/venv/bin/activate && pip install -r /home/ubuntu/canonicaliser_api/requirements.txt' returned a non-zero code: 1

但这没有任何意义,我通过ADD在Dockerfile中添加了整个代码目录.我在这里错过了什么吗？

bash-3.2$ls canonicaliser_api/requirements.txt 
canonicaliser_api/requirements.txt
bash-3.2$

最佳答案 用法是：ADD [源目录或URL] [目标目录]

您需要将文件夹名称添加到目标：

ADD canonicaliser_api /home/ubuntu/canonicaliser_api
