我的Dockerfile遇到问题并设置了正确的工作目录

Question

这是我的第一个Dockerfile，这是我到目前为止所拥有的。

FROM python:3.6-stretch


# install build utilities
RUN apt-get update && \
    apt-get install -y gcc make apt-transport-https ca-certificates build-essential

# check our python environment
RUN python3 --version
RUN pip3 --version

# set the working directory for containers
WORKDIR  /usr/src/toxic-content-monitoring

# Installing python dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy all the files from the project’s root to the working directory
COPY src/ /src/
RUN ls -la /src/*

# Running Python Application
CMD ["python3", "/src/main.py"]

但是当我尝试运行docker映像时，找不到数据文件夹内的文件。 这是我的项目结构的图片。

将其更改为建议的内容，但仍然出现错误。

FROM python:3.6-stretch

# install build utilities
RUN apt-get update && \
    apt-get install -y gcc make apt-transport-https ca-certificates build-essential

# check our python environment
RUN python3 --version
RUN pip3 --version

# set the working directory for containers
WORKDIR  /usr/src/toxic-content-monitoring

# Installing python dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy all the files from the project’s root to the working directory
COPY src/ /src/
COPY data /data/
RUN ls -la /src/*

# Running Python Application
CMD ["python3", "/src/main.py"]

这是错误消息。

我相信您的Dockerfile中缺少COPY data/ /data/命令。您仅在复制src文件夹，而不在复制数据。请在Dockerfile中的COPY src / / src /行之后添加COPY data /data/，然后尝试一下。
