python - 在 docker 中激活 conda 环境

Question

我需要在 docker 中激活环境并在此环境中运行命令。我创建了环境，但随后我尝试激活此环境并以这种方式运行命令：

CMD [ "source activate mro_env && ipython kernel install --user --name=mro_env" ]

但是当我运行 docker 时出现错误：

[FATAL tini (8)] exec source activate mro_env && ipython kernel install 
--user --name=mro_env failed: No such file or directory

这是整个 Dockerfile：

FROM continuumio/miniconda3

ADD /src/mro_env.yml /src/mro_env.yml
RUN conda env create -f /src/mro_env.yml

# Pull the environment name out of the mro_env.yml
RUN echo "source activate $(head -1 /src/mro_env.yml | cut -d' ' -f2)" > ~/.bashrc
ENV PATH /opt/conda/envs/$(head -1 /src/mro_env.yml | cut -d' ' -f2)/bin:$PATH

CMD [ "source activate mro_env && ipython kernel install --user --name=mro_env" ]

遵循本教程并且它有效。示例 Dockerfile：

FROM continuumio/miniconda
WORKDIR /usr/src/app
COPY ./ ./
RUN conda env create -f environment.yml

# Make RUN commands use the new environment:
SHELL ["conda", "run", "-n", "myenv", "/bin/bash", "-c"]

EXPOSE 5003
# The code to run when container is started:
ENTRYPOINT ["conda", "run", "-n", "myenv", "python3", "src/server.py"]

更新：

如果您使用 4.9 版本的 conda，您可以使用“conda run --no-capture-output”来不缓冲 IO。更新的 Dockerfile：

FROM continuumio/miniconda
WORKDIR /usr/src/app
COPY ./ ./
RUN conda env create -f environment.yml

# Make RUN commands use the new environment:
SHELL ["conda", "run", "--no-capture-output", "-n", "myenv", "/bin/bash", "-c"]

EXPOSE 5003
# The code to run when container is started:
ENTRYPOINT ["conda", "run", "--no-capture-output", "-n", "myenv", "python3", "src/server.py"]
