Jupyterlab and C++

Today I tried to create a Dockerfile for XEUS-Cling in Jupyterlab. The challenge was, that the installation is done with conda which is a little bit tricky to use together with Docker. After some unsuccessful trials, I finally came up with the following working solution:

FROM continuumio/miniconda3:4.8.2-alpine
MAINTAINER phil schatzmann
USER root
RUN apk add --no-cache bash
SHELL ["/bin/bash","--login","-c"]
ENV PATH /opt/conda/envs/cling/bin:/opt/conda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
RUN conda create -y -n cling xeus-cling xeus-python jupyterlab -c conda-forge
WORKDIR /home/xeus-cling
EXPOSE 8888
CMD ["jupyter", "lab", "--port=8888", "--no-browser", "--allow-root", "--ip=0.0.0.0" ]

I am using it together with docker-compose. The docker-compose.yml looks as follows:

version: '3.2'
services:
  cling:
    image: pschatzmann/xeus-cling
    container_name: cling
    restart: always
    ports:
      - 8888:8888
    volumes:
      - /srv/data-science:/home/xeus-cling
      - /data:/data
    environment:
      - TZ=Europe/Zurich
    dns:
      - 8.8.8.8 

Finally I double check if it is working properly:
