Upgrading to JupyterHub version 0.8
===================================
This document will assist you in upgrading an existing JupyterHub deployment
from version 0.7 to version 0.8.
Upgrade checklist
-----------------
0. Review the release notes. Review any deprecated features and pay attention
to any backwards incompatible changes
1. Backup JupyterHub database:
- ``jupyterhub.sqlite`` when using the default sqlite database
- Your JupyterHub database when using an RDBMS
2. Backup the existing JupyterHub configuration file: ``jupyterhub_config.py``
3. Shutdown the Hub
4. Upgrade JupyterHub
- ``pip install -U jupyterhub`` when using ``pip``
- ``conda upgrade jupyterhub`` when using ``conda``
5. Upgrade the database using run ```jupyterhub upgrade-db``
6. Update the JupyterHub configuration file ``jupyterhub_config.py``
Backup JupyterHub database
--------------------------
To prevent unintended loss of data or configuration information, you should
back up the JupyterHub database (the default SQLite database or a RDBMS
database using PostgreSQL, MySQL, or others supported by SQLAlchemy):
- If using the default SQLite database, back up the ``jupyterhub.sqlite``
database.
- If using an RDBMS database such as PostgreSQL, MySQL, or other supported by
SQLAlchemy, back up the JupyterHub database.
.. note::
Losing the Hub database is often not a big deal. Information that resides only
in the Hub database includes:
- active login tokens (user cookies, service tokens)
- users added via GitHub UI, instead of config files
- info about running servers
If the following conditions are true, you should be fine clearing the Hub
database and starting over:
- users specified in config file
- user servers are stopped during upgrade
- don't mind causing users to login again after upgrade
Backup JupyterHub configuration file
------------------------------------
Backup up your configuration file, ``jupyterhub_config.py``, to a secure
location.
Shutdown JupyterHub
-------------------
- Prior to shutting down JupyterHub, you should notify the Hub users of the
scheduled downtime.
- Shutdown the JupyterHub service.
Upgrade JupyterHub
------------------
Follow directions that correspond to your package manager, ``pip`` or ``conda``,
for the new JupyterHub release:
- ``pip install -U jupyterhub`` for ``pip``
- ``conda upgrade jupyterhub`` for ``conda``
Upgrade the proxy, authenticator, or spawner if needed.
Upgrade JupyterHub database
---------------------------
To run the upgrade process for JupyterHub databases, enter::
jupyterhub upgrade-db
Update the JupyterHub configuration file
----------------------------------------
Create a new JupyterHub configuration file or edit a copy of the existing
file ``jupyterhub_config.py``.
Start JupyterHub
----------------
Start JupyterHub with the same command that you used before the upgrade.
