Simple test

jupyter notebook notebooks

Test the image from source

Build it to have it locally:

docker build -t grass-point-cloud-workshop .

Run it to test it:

docker run -it --rm -p 8888:8888 grass-point-cloud-workshop

Run tmpnb

Generate tokens:

export TOKEN=$( head -c 30 /dev/urandom | xxd -p )
export USER_TOKEN=$( head -c 30 /dev/urandom | xxd -p )
echo $TOKEN
echo $USER_TOKEN

Run the proxy:

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=proxy \
    jupyter/configurable-http-proxy --default-target http://127.0.0.1:9999

Run tmpnb:

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=tmpnb \
    -v /var/run/docker.sock:/docker.sock jupyter/tmpnb \
    python orchestrate.py --log-to-stderr --logging=debug \
    --use-tokens=False --image='grass-gis-notebook' \
    --command="start-notebook.sh \"--NotebookApp.base_url={base_path} --ip=0.0.0.0 --port {port} --NotebookApp.trust_xheaders=True --NotebookApp.token=$USER_TOKEN\""
