Docker 无法创建 conda 虚拟环境

Question

I'm trying to dockerize a python application, using conda for package management.

I generated a specfile using:

conda list --explicit > spec-file.txt

I have the following code in my Dockerfile:

FROM conda/miniconda3

RUN conda create -n env --file ./spec-file.txt
RUN echo "source activate env" > ~/.bashrc
ENV PATH /opt/conda/envs/env/bin:$PATH

When I run docker-compose build , it produced the following error:

CondaFileIOError: './spec-file.txt'. [Errno 2] No such file or directory: './spec-file.txt'

The Dockerfile and the specfile are both in the same directory. I've tried using absolute paths and that didn't work either.

Answer 1

Turns out I needed to add the line:

COPY ./spec-file.txt .

Before trying to create the environment.
