Meilisearch for Open edX (Tutor Plugin)

This is a plugin for Tutor 18 (Open edX "Redwood" release) that provides Meilisearch to the platform, so it can be used as a search engine to power content search.

⭐️ This plugin isn't needed with Tutor 19+ (Open edX Sumac+), as Meilisearch functionality is now built in. ⭐️

Installation

Currently, you need to clone this repo from GitHub then install it into your tutor virtual environment with:

pip install -e ./tutor-contrib-meilisearch

Then, to enable this plugin, run:

tutor plugins enable meilisearch

If you have an already running platform, initialize this plugin with a command like the following:

tutor [local|dev|k8s] do init --limit=meilisearch

Or use tutor [local|dev|k8s] launch -I to re-launch the platform (takes much longer).

Configuration

• MEILISEARCH_INDEX_PREFIX (default: "tutor_")
• MEILISEARCH_PUBLIC_HOST (default: "meilisearch.{{ LMS_HOST }}")
• MEILISEARCH_DOCKER_IMAGE (default: "docker.io/getmeili/meilisearch:v1.8)
• MEILISEARCH_MASTER_KEY The master key. Only required to generate the API key (default: auto-generated).
• MEILISEARCH_API_KEY The API key (or tenant key) to use for this Open edX instance (default: auto-generated using the master key).

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

Upgrading

If you upgrade this plugin or change the MEILISEARCH_DOCKER_IMAGE setting, you may get a new version of Meilisearch. In that case, the meilisearch Docker service will fail to start because the index format is from an older version. For large instances, you can follow the Meilisearch update procedure (basically, dump the index contents to a file, upgrade it, then restore from the data dump file). For development and smaller installations, the easier way is to follow this procedure:

tutor [local|dev] stop meilisearch
cd "$(tutor config printroot)/data/meilisearch"
mv data.ms "data.ms.$(date +%Y-%m-%d)"
tutor config save
tutor [local|dev] start -d meilisearch
tutor [local|dev] do init --limit=meilisearch

TODO

Currently, this plugin always deploys a new instance of Meilisearch. It should be modified to support using an existing external instance if desired.

DNS records

For production use, it is assumed that the MEILISEARCH_PUBLIC_HOST DNS record points to your server.

In development mode, Meilisearch is available at http://meilisearch.local.edly.io:7700.

Web UI

The Meilisearch web UI can be accessed at http(s)://<MEILISEARCH_PUBLIC_HOST>. For development, this is usually http://meilisearch.local.edly.io:7700/

An API key for accessing the UI can be obtained with:

tutor config printvalue MEILISEARCH_API_KEY

Troubleshooting

TBD
