apparvi/cv2019 repository overview

# Download image
docker pull apparvi/cv2019

# Create a container and run with:
docker run -it --name cv2019 --user $(id -u):$(id -g) --group-add users -v "$(pwd)":/home/jovyan/work -p 8888:8888 apparvi/cv2019 start.sh jupyter lab --NotebookApp.custom_display_url='http://127.0.0.1:8888' --notebook-dir=/home/jovyan/work

# Command explained (full command below):
# -it     attach terminal
# --name cv2019     give name to the container for easier reference later
# --user $(id -u):$(id -g) use your own user id and group id to get proper file permissions for the files created in shard volumes
# --group-add users      add your user id to group users to get access to some important folders within the image
# -v "$(pwd)":/home/jovyan/work     mount current wd to containers wd. In the image your user is "jovyan"(inhabitant of Jupyter)
# -p 8888:8888      map host port 8888 to be used for Jupyter Notebook
# apparvi/cv2019     specify the image to be used
# start-notebook.sh jupyter lab     image entry point, use jupyter lab instead of notebook
# --NotebookApp.custom_display_url='http://127.0.0.1:8888'     fix the terminal link
# --notebook-dir=/home/jovyan/work     specify the Jupyter working directory

# Start the same container later
docker start -i cv2019
