# Jupyter Docker Image

This directory contains build files for a complete jupyter environment. It is based off the following repositories:

 - https://github.com/jupyter/docker-stacks
 - https://github.com/rgriffogoes/scraper-notebook
 - https://github.com/sharpTrick/sage-notebook

The images these files produce contain everything you could possibly want in a jupyter notebook. Additional packages can be installed in notebooks with `%%bash` magic.

## Building the Image

To build this image, run `build/build.fish.` Edit the script to customize the image.

## Image contents
 - jupyter + all dependencies
 - Python + many packages
 - Octave
 - R
 - Julia


## TODO
 - Fix sage
 - Haskell ([source](https://github.com/IHaskell/ihaskell-notebook))
 - Maxima Kernel


## Configuration

Change the permissions on the configuration volume (see `docker-compose.yml`) if you get errors.

You may want to add the following lines to `jupyter_notebook_config.py`:

```python
c.ServerApp.local_hostnames = ["localhost", "0.0.0.0"]
c.ServerApp.token = "a_long_random_string"

c.TagRemovePreprocessor.enabled = True
c.TagRemovePreprocessor.remove_cell_tags = ("hide_cell",)
c.TagRemovePreprocessor.remove_all_outputs_tags = ("hide_output",)
c.TagRemovePreprocessor.remove_input_tags = ("hide_input",)
```

The first sets `0.0.0.0` to the allowed local hostname list. This prevents a possible "connection reset" when connecting to the docker container. Opens jupyter up to the outside internet, but you should have your inbound ports firewalled off anyway.

The second line sets a persistent token. If this config value is unset, jupyter will generate a new one on each run, making it hard to make a one-click bookmark.


### As a Server

Add the following lines and remove ``c.ServerApp.token``. This allows remote access and enables password authentication. **Warning:** be careful. Anyone with access to this server has a shell in your system.

```python
c.NotebookApp.allow_remote_access = True
c.NotebookApp.allow_origin = "*"
c.ServerApp.ip = "*"
c.ServerApp.password = u"pwd_str"
c.ServerApp.open_browser = False
```

 Passwords can be generated with

```python
from jupyter_server.auth import passwd
passwd()
```
