Introduction
|
|
============
|
|
|
|
`Open edX <http://open.edx.org/>`_ is a thriving open source project, backed by a great community, for running an online learning platform at scale. Historically, it's always been :ref:`difficult <native>` to install Open edX. The goal of Tutor is to solve this issue.
|
|
|
|
Tutor simplifies the deployment of Open edX by:
|
|
|
|
1. Separating the configuration logic from the deployment platforms.
|
|
2. Running application processes in cleanly separated `docker containers <https://www.docker.com/resources/what-container>`_.

Because Docker containers are becoming an industry-wide standard, that means that with Tutor it becomes possible to run Open edX anywhere: for now, Tutor supports deploying on a local server, with `docker-compose <https://docs.docker.com/compose/overview/>`_, and in a large cluster, with `Kubernetes <http://kubernetes.io/>`_. But in the future, Tutor may support other deployment platforms.

How does Tutor work?
|
|
--------------------
|
|
|
|
You can experiment with Tutor very quickly: start by `installing <install>`_ Tutor. Then run::
|
|
|
|
tutor config save --interactive
|
|
|
|
This command does two things:
|
|
|
|
1. Generate a ``config.yml`` configuration file: this file contains core :ref:`configuration parameters <configuration>` for your Open edX platforms, such as passwords and feature flags.
|
|
2. Generate an ``env/`` folder, which we call the Tutor "environment", and which contains all the files that are necessary to run an Open edX platform: these are mostly Open edX configuration files.
|
|
|
|
All these files are stored in a single folder, called the Tutor project root. On Linux, this folder is in ``~/.local/share/tutor`` and on Mac OS it is ``~/Library/Application Support/tutor``.
|
|
|
|
The values from ``config.yml`` are used to generate the environment files in ``env/``. As a consequence, **every time the values from** ``config.yml`` **are modified, the environment must be regenerated**. This can be done with::
|
|
|
|
tutor config save
|
|
|
|
Another consequence is that **any manual change made to a file in** ``env/`` **will be overwritten by** ``tutor config save`` **commands**. Consider yourself warned ;-)
|
|
|
|
Running Open edX
|
|
----------------
|
|
|
|
Now that you have generated a configuration and environment, you probably want to run Open edX.
|
|
|
|
- The most simple and popular use case is to :ref:`run Open edX locally, on a single server <local>`, with docker-compose.
|
|
- If you have a running cluster, you can use Tutor to :ref:`deploy Open edX on Kubernetes <k8s>`.
|
|
- Are you an Open edX developer? You can use Tutor for :ref:`hacking into the internals of edx-platform <development>`.
