Dockerfile is building but not launching and I have no idea why

I’m trying to get IHaskell running on mybinder.org, and I’ve made what I think is a simple Dockerfile that builds correctly but fails to launch. I’ve reproduced it below:

FROM fpco/stack-build:lts-11.2

# Install all necessary Ubuntu packages
RUN apt-get update && apt-get install -y python3-pip libgmp-dev libmagic-dev libtinfo-dev libzmq3-dev libcairo2-dev libpango1.0-dev libblas-dev liblapack-dev gcc g++ && \
    rm -rf /var/lib/apt/lists/*

# Install Jupyter notebook
RUN pip3 install -U jupyter

ENV LANG en_US.UTF-8
ENV NB_USER jovyan
ENV NB_UID 1000
ENV HOME /home/${NB_USER}

RUN adduser --disabled-password \
    --gecos "Default user" \
    --uid ${NB_UID} \
    ${NB_USER}

COPY . ${HOME}
USER root
RUN chown -R ${NB_UID} ${HOME}
USER ${NB_USER}

ENV PATH $(stack path --local-install-root)/bin:$(stack path --snapshot-install-root)/bin:$(stack path --compiler-bin):${HOME}/.local/bin:${PATH}
ENV GHC_PACKAGE_PATH $(stack path --ghc-package-path)
RUN stack config set system-ghc --global true
RUN stack install ihaskell
RUN ihaskell install --stack

I’ve looked at the documentation on using Dockerfiles and I think I’m doing the right thing with installing Jupyter and running under the user jovyan with ID 1000. When I do a docker build locally and run it myself it seems to work correctly:

$ docker build -t ihaskell-mybinder:v1 .
$ docker run -it -p8888:8888 ihaskell-mybinder:v1 jupyter notebook --ip='0.0.0.0'

Is there something obvious I’m missing? I’m relatively inexperienced with Docker so any help would be appreciated.

I will make a PR 😄

Adding the CMD seemed to make no difference.
