构建 docker 容器期间缺少 env yaml 文件中的 pip 依赖项

Question

我有以下 conda 环境 YAML 文件：

name: someapp
channels:
  - conda-forge
  - defaults
dependencies:
  - flask=2.2.2
  - pandas=1.5.3
  - pip=23.0.1
  - python=3.11.3
  - pip:
      - psycopg2-binary==2.9.9
      - requests==2.32.3
prefix: /usr/local/anaconda3/envs/someapp

我希望在构建我的 docker 容器（用于 Flask 应用程序）时创建此环境，但在启动

ModuleNotFoundError: No module named 'requests'

文件（其中我使用以下 DockerFile 导入

server.py

）时出现

requests

错误：

FROM continuumio/miniconda3

RUN apt-get update && \
    apt-get install --yes --no-install-recommends \
    && apt-get clean

WORKDIR /app/services/back_end/

COPY ./environment.yml ./environment_server.yml
RUN conda env create -f ./environment_server.yml

# added line to try to install but doesn't work
RUN /bin/bash -c "source activate someapp && pip install requests" 

RUN echo "source activate someapp" > ~/.bashrc
ENV PATH /opt/conda/envs/someapp/bin:$PATH

EXPOSE 6969

ENTRYPOINT ["python", "server.py"]

Answer 1

要在您的环境中运行 conda，您应该使用 conda 命令，但在您的情况下，您应该更改容器的入口点。

看起来应该是这样的

ENTRYPOINT ["conda", "run", "--no-capture-output", "-n", "someapp", "python", "server.py"]
