在Docker中激活conda环境

问题描述

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，但随后尝试激活该环境并以这种方式运行命令:

I need to activate environment in docker and run a command in this environment.I create the environment, but then I try to activate this environment and run the command in this way:

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

但是当我运行docker时出现错误:

but when I ran docker I get an error:

[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:

This is the whole 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" ]

推荐答案

您可以设置CONDA_DEFAULT_ENV

You can set CONDA_DEFAULT_ENV

赞:

FROM continuumio/miniconda3

ARG conda_env=mro_env

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

ENV PATH /opt/conda/envs/$conda_env/bin:$PATH
ENV CONDA_DEFAULT_ENV $conda_env

CMD [ "python", "test.py" ]

更新:

最好使用激活.为我工作:

Better use activate. Work for me:

FROM continuumio/miniconda3

ADD /src/environment.yml /src/environment.yml

RUN conda env create -f /src/environment.yml
ENV PATH /opt/conda/envs/mro_env/bin:$PATH
RUN /bin/bash -c "source activate mro_env"

CMD [ "python", "test.py" ]
