Using Jupyterhub with pyenv

I use jupyterhub a lot for data exploration and this is my setup for running from a remote workstation so I can access it in a browser from anywhere

Using JupyterHub

Installation Instructions

Python 3.4 or greater

https://github.com/jupyterhub/jupyterhub

# With ssl
$ jupyterhub --ip 10.0.1.2 --port 443 --ssl-key my_ssl.key --ssl-cert my_ssl.cert

# Without ssl
$ jupyterhub --ip 10.0.1.2 --port 8000

Multiple pyenv/venv kernels

Ref: https://www.alfredo.motta.name/create-isolated-jupyter-ipython-kernels-with-pyenv-and-virtualenv/

Install pyenv

See kb article on pyenv

Install ipykernel on the env you need

$ pyenv local my_venv

$ pip install ipykernel

# Confirm jupyter is installed correctly
$ pip list | grep jupyter
jupyter-client (4.1.1)
jupyter-core (4.0.6)

Find where Jupyter looks for kernel configs

$ jupyter --paths
config:
    /home/elijahc/.jupyter
    /usr/local/etc/jupyter
    /etc/jupyter
data:
    /home/elijahc/.local/share/jupyter
    /usr/local/share/jupyter
    /usr/share/jupyter
runtime:
    /run/user/1000/jupyter

For global kernels for all users store them at /usr/local/share/jupyter or /usr/share/jupyter

Make a new directory for the new kernel

$ sudo mkdir -p /usr/local/share/jupyter/kernels/my_venv

Add the new kernel.json file

$ sudo touch /usr/local/share/jupyter/kernels/my_venv/kernel.json

kernel.json

$ cat kernel.json
{
 "argv": [ "/home/elijahc/.pyenv/versions/my_venv/bin/python", "-m", "ipykernel",
          "-f", "{connection_file}"],
 "display_name": "my_venv",
 "language": "python"
}
