Kolibri README
==============

This Ansible role installs `Kolibri <https://learningequality.org/kolibri/>`_ within `Internet-in-a-Box (IIAB) <http://internet-in-a-box.org/>`_.  Kolibri is an open-source educational platform specially designed to provide offline access to a wide range of quality, openly licensed educational contents in low-resource contexts like rural schools, refugee camps, orphanages, and also in non-formal school programs.

Kolibri's online User Guide is here: `https://kolibri.readthedocs.io <https://kolibri.readthedocs.io/>`_

Using It
--------

If enabled and with the default settings, Kolibri should be accessible at: http://box/kolibri

To login to Kolibri enter::

  Username: Admin
  Password: changeme

Configuration Parameters
------------------------

Please look in `/opt/iiab/iiab/roles/kolibri/defaults/main.yml <defaults/main.yml>`_ for the default values of the various install parameters.  Everything in this README assumes the default values.

Automatic Device Provisioning
-----------------------------

When kolibri_provision is enabled (e.g. in `/etc/iiab/local_vars.yml <http://FAQ.IIAB.IO#What_is_local_vars.yml_and_how_do_I_customize_it.3F>`_) the installation will set up the following defaults::

  Kolibri Facility name: 'Kolibri-in-a-Box'
  Kolibri Preset type: formal     # Options: formal, nonformal, informal
  Kolibri default language: en    # Options: ar, bn-bd, en, es-es, fa, fr-fr, hi-in, mr, nyn, pt-br, sw-tz, ta, te, ur-pk, yo, zu
  Kolibri Admin username: Admin
  Kolibri Admin password: changeme

*Feel free to override any of the above, by copying the relevant line from /opt/iiab/iiab/roles/kolibri/defaults/main.yml to /etc/iiab/local_vars.yml (then run 'cd /opt/iiab/iiab' followed by './runrole kolibri' per IIAB's general guidelines at http://FAQ.IIAB.IO).*

Cloning Content
---------------

Kolibri 0.10 introduced ``kolibri manage deprovision`` which will remove user configurations, leaving content intact — i.e. if student and teacher privacy requires their records be deleted.  You can then copy or clone /library/kolibri to a new location, or to a new school entirely.

Troubleshooting
---------------

An unproxied version of Kolibri is available here if necessary: http://box:8009/kolibri/

You can run the server manually with the following commands::

  systemctl stop kolibri           # Make sure the systemd service is not running
  export KOLIBRI_HOME=/library/kolibri
  export KOLIBRI_HTTP_PORT=8009    # Otherwise Kolibri will try to run on default port 8080
  kolibri start

To return to using the systemd unit file::

  kolibri stop
  systemctl start kolibri

Known Issues
------------

* Kolibri migrations can take a long time on a Raspberry Pi.  These long-running migrations could cause kolibri service timeouts.  Try running migrations manually using command ``kolibri manage migrate`` after following the troubleshooting instructions above.  Kolibri developers are trying to address this issue.  (See `learningequality/kolibri#4310 <https://github.com/learningequality/kolibri/issues/4310>`_)

* Loading channels can take a long time on a Raspberry Pi.  When generating channel contents for Khan Academy, the step indicated as “Generating channel listing.  This could take a few minutes…” could mean ~30 minutes.  The device’s computation power is the bottleneck.  You might get logged out while waiting, but this is harmless and the process will continue.  Sit tight!
