Object storage for Open edX with `MinIO <https://www.minio.io/>`_
=================================================================

This is a plugin for `Tutor <https://docs.tutor.overhang.io>`_ that provides S3-like object storage for Open edX platforms. It's S3, but without the dependency on AWS. This is achieved thanks to `MinIO <https://www.minio.io/>`_, an open source project that provides object storage with an API compatible with S3.

In particular, this plugin is essential for `Kubernetes deployment <https://docs.tutor.overhang.io/k8s.html>`_.

Installation
------------

The plugin is currently bundled with the `binary releases of Tutor <https://github.com/overhangio/tutor/releases>`_. If you have installed Tutor from source, you will have to install this plugin from source, too::
  
    pip install tutor-minio

Then, to enable this plugin, run::
  
    tutor plugins enable minio

Configuration
-------------

- ``MINIO_BUCKET_NAME`` (default: ``"openedx"``)
- ``MINIO_FILE_UPLOAD_BUCKET_NAME`` (default: ``"openedxuploads"``)
- ``MINIO_COURSE_IMPORT_EXPORT_BUCKET`` (default: ``"openedxcourseimportexport"``)
- ``MINIO_HOST`` (default: ``"minio.{{ LMS_HOST }}"``)
- ``MINIO_DOCKER_REGISTRY`` (default: ``"{{ DOCKER_REGISTRY }}"``)

These values can be modified with ``tutor config save --set PARAM_NAME=VALUE`` commands.

DNS records
-----------

It is assumed that the ``MINIO_HOST`` DNS record points to your server. When running MinIO on your laptop, you should point your services to ``minio.localhost``::

    tutor config save --set MINIO_HOST=minio.localhost

Web UI
------

The MinIO web UI can be accessed at http://<MINIO_HOST>. The credentials for accessing the UI can be obtained with::
