Maintenir une instance Wikibase
Vous trouverez sur cette page quelques ressources pour vous documenter sur votre instance de Wikibase et la garder fonctionnelle et à jour.



Aperçu de l'architecture
D'abord il est important de comprendre ce que vous avez entre les mains. Take a look at our Docker architecture overview.

Voici un tableau de l'architecture avec un diagramme.





Outillage Docker
The best tool for managing your Docker install is the one you used to get it going in the first place: docker-compose. This manual can’t possibly replace a grounding in Docker, so check out Docker’s own command references for docker-compose and the docker engine.

That said, here are some starter commands that might come in handy.



Obtenir un shell de commande sur un conteneur
You won’t need it for typical Wikibase activity, but for Docker beginners here’s one very useful command that connects to a running container:

docker exec -it &lt;container name&gt; bash



Copier un fichier dans votre répertoire local
docker cp wbdocker_wikibase_1:/var/www/html/LocalSettings.php LocalSettings.php

This also works in the other direction, and the combination is useful for, say, grabbing your LocalSettings.php, editing it and putting it right back.

docker cp LocalSettings.php wbdocker_wikibase_1:/var/www/html/LocalSettings.php

Read Adam Shorland’s excellent blog post for more detail on modifying files on containers.



Arrêter les conteneurs Docker
This command stops the Docker containers, leaving the machines (and of course all data) intact:

As you might imagine, you can use  to start them again.



Supprimer les conteneurs en préservant les données
This command removes the containers but preserves all data in MySQL, MediaWiki and the query service in Docker volumes.



Journaux
Chaque application de la grappe Wikibase génère ses propres traces dans le journal. Consultez la documentation propre à chaque service pour savoir comment lire les journaux.

In the directory where you placed your  file, run the   command and the name of the service (check the table above) to see its logs. Par exemple :

user@host:~/docker$ docker-compose logs -f --tail=100 mysql mysql_1 | 2019-12-31 10:00:00+00:00 [Note] [Entrypoint]: Entrypoint script for MySQL Server started. mysql_1 | 2019-12-31 10:00:00+00:00 [Note] [Entrypoint]: Switching to dedicated user 'mysql' ...



Sauvegarde et restauration
Les données de votre instance Wikibase sont précieuses. What would happen if your datacenter burnt down? How long would it take to rebuild? Regular backups and tested restores of data are vital.

Generally, there are two bodies of data you’ll need to back up: the MediaWiki/Wikibase filesystem and, more importantly, the MySQL database. First and foremost, we recommend reading the Wikibase Docker install doc to get the lay of the land.



Au niveau Docker
Since this is a Docker install, backup using Docker tools is recommended.

Docker-level backup is explained in some detail here. It involves backing up the Docker volumes and dumping out the database with mysqldump.

For a helpful overview of Docker data backup and restore, including the use of the  and   commands, read this excellent StackOverflow post. It’s been updated several times since its original posting in 2014 and constitutes a great tour and jumping-off point for the docker command-line reference linked above.



Au niveau conteneur
Backup on the container level is not an easy proposition; we cover it here mainly to present a more complete picture of MediaWiki and Wikibase under the hood.

To that end, read the documentation on, bearing in mind that the work needs to be done from within the containers (cf. Docker tooling above) and the data extracted and placed somewhere safe outside of Docker.



Outils Wiki
Wikibase est une extension de MediaWiki. Much of the functionality you’ll be working with is actually that of MediaWiki, so consult the and the. Of particular note:


 * - guide utilisateur
 * - gestion des droits utilisateurs
 * - guide de l'administrateur Wiki

Mise à jour
Keeping software up to date is the only way to obtain new features, not to mention how important it is to apply bug and security fixes.

To update Wikibase on Docker, read our upgrade documentation.

Updating a manual install of the Wikibase suite isn't as straightforward: it involves upgrading MediaWiki itself (see the MediaWiki update documentation) and then the individual software components.
