binder-demo-template

About this template

This template can be used to create SNAP based notebooks to be demoed or exploited on Binder.

Using this template

Update the conda dependencies

Create a file named environment.yml with the additional conda dependencies:

Below an example

channels:
 - conda-forge
dependencies:
 - <your conda package>

Update other dependencies

Edit the file .binder/Dockerfile and add the additional tools with apt.

Example:

FROM terradue/docker-snap-binder:latest

USER root
# install additional packages here

RUN apt-get install tree

USER jovyan

COPY --chown=jovyan:jovyan . /home/jovyan

RUN test -f ${HOME}/environment.yml && mamba env update -p /srv/conda/envs/env_snap -f ${HOME}/environment.yml  && \
    test -f ${HOME}/postBuild && chmod +x ${HOME}/postBuild && ${HOME}/postBuild || exit 0

Update SNAP modules

SNAP modules can be updated or installed in a postBuild bash script.

Below an example:

#!/bin/bash

export PREFIX=/srv/conda/envs/env_snap

( cmdpid=$BASHPID; (sleep 60; kill $cmdpid) & exec $PREFIX/snap/bin/snap --nosplash --nogui --modules --update org.esa.snap.snap.ndvi )

Testing the docker image

You can test the docker image before pushing your changes to GitHub with:

docker build -f .binder/Dockerfile -t img-test .

And once built, do:

docker run --rm -it -p 8888:8888 -v $PWD:/home/jovyan img-test:latest jupyter lab --port=8888 --ip=0.0.0.0 --NotebookApp.token='' --no-browser

And open a browser tab at http://0.0.0.0:8888/lab

Now delete everything above and create your README here. Don't forget to update the Binder URL
