Help pulling docker image into singularity

[GregorySchwing]

I built a docker image which automatically has the base environment of a conda environment activated. when I pull this into singularity, singularity doesn't know the path to python.

"/usr/bin/env python" says command not found.

Here is the docker image link

docker pull go2432/openff-toolkit:0.4.2

How do I set up my docker image so this works flawlessly with singularity?

I got this working evenually using hte attached dockerfile.

I think the Bolded line was the trick.

FROM condaforge/miniforge3

COPY --chown=$MAMBA_USER:$MAMBA_USER envs/openff-toolkit.yml env.yml

RUN mamba env update --file=env.yml -n base && mamba clean --all

RUN mamba update -c conda-forge procps-ng && mamba clean --all --yes

RUN mamba init

**ENV BASH_ENV=/root/.bashrc**

CMD ["/bin/bash"]
