我用Dockerfile成功构建了一个容器.但是,我的代码在容器中不起作用.如果我手动安装所有包,它确实有效.我假设我弄乱了导致docker没有正确安装软件包的东西.所以,我想检查是否在Docker容器中安装了python包.检查它的最佳方法是什么？
我使用的Dockerfile：
# Update the sources list
RUN sudo apt-get update
# Install basic applications
RUN sudo apt-get install -y tar git curl nano wget dialog net-tools build-essential
# First install ZeroMQ
RUN sudo apt-get install -y libzmq-dev
# Install libevent
RUN sudo apt-get install -y libevent-dev
# Install Python and Basic Python Tools
RUN sudo apt-get install -y python python-dev python-setuptools
RUN sudo apt-get install -y python-pip
# Add the current directory to the container
ADD . /root/code
# Get pip to download and install requirements:
RUN sudo pip install -r /root/code/requirements.txt
# Expose ports
EXPOSE 80 4242
# Define working directory.
WORKDIR /root/code
# Start the tcp server.
CMD python app.py
我使用的requirements.txt：
gevent==1.0.1
greenlet==0.4.5
msgpack-python==0.4.2
pyzmq==13.1.0
wsgiref==0.1.2
zerorpc==0.4.4
