 Docker compose sources to start planete-casio's wiki and tools
 
 
+## Volumes
+
+The wiki is the only statefull tool of this setup. All the data will be stored in volumes that will be in the `volumes` directory.
+
+* `mariadb-wiki` : This is the raw storage of the db. Don't delete this. Avoid copying this between mysql versions, use SQL dumps instead.
+* `wiki-fr-images` and `wiki-en-images` : Upload storages of the wiki. You have to restore this if you restore the db. It also contains some image caches.
+* `wiki-fr-cache` and `wiki-en-caches` : This is a cache used by the wiki to avoid recomputing all pages for all users. You can safely delete this volume.
+
 ## Deployment

+The following keys are required:
+
+* `WIKI_BASE_URI`: Wiki base uri with protocol, hostname and port. For instance `https://wiki.planet-casio.com` or `http://wiki.local:8080`
+* `WIKI_EN_SECRET_KEY` and `WIKI_FR_SECRET_KEY`: [Secret key](https://www.mediawiki.org/wiki/Manual:$wgSecretKey) of the wiki. Should be a 64-character random string.
+* `WIKI_DB_ROOT_PASSWORD`: Password of the `root` user on the database that can, for instance, create other users on the DB.
+* `WIKI_DB_WIKI_PASSWORD`: Password of the `wiki` user on the database. This account is used by the application and can only edit the `wiki` database.
+* `HTTP_BIND`: Port and address on which we will bind the http server
+  * This docker compose doesn't support https, so we will generally expose it only to localhost on a given port to have another local server http using it on the host. For instance on port `8000`: `127.0.0.1:8000`.
+  * If you want to test the server remotely without having another http server, you can expose it directly to the outside world by giving only a port number : `8000`.
+* `WIKI_HOSTNAME`: Hostname(s) on which the wiki will be hosted. You can use multiple hostnames by splitting them with spaces.
+* `TOOLS_HOSTNAME`: Hostname(s) on which the tools will be hosted. You can use multiple hostnames by splitting them with spaces.
+
+The following keys are optionnal:
+
+* `WIKI_EN_UPGRADE_KEY` and `WIKI_FR_UPGRADE_KEY`: [Upgrade password](https://www.mediawiki.org/wiki/Manual:$wgUpgradeKey) of the wiki. Should be a random non-guessable password. Should be left empty when upgrade is not in progress.
+* `WIKI_DEBUG`: Enable the debug mode of the wiki if set to 1. To disable debug mode,  leave it empty. When enabled it activates:
+  * The debug log in `(fr|en)/cache/debug.log`
+  * Show php and sql errors
+  * Show details and backtrace of exceptions

 ```
 
+Once the database started, the tools should work as expected. However you should get the following error on the wiki
+
+```
+MediaWiki internal error.
+```
+
+This is generally because the wiki database has not been filled with a structure. If you want to get more details, you can restart the `docker-compose` with `DEBUG=1` in the `.env` file.
+
+### Init the wiki
+
+To init the wiki you will need a mysql dump of the current wiki. We don't have one without personnal data, but if really needed this might be created and upload to this repo.
+
+First, dump the current database with somehting like this
+
+```
+# This should ask you the password of the use `wiki` and create the dump
+mysqldump -h old-pc-sql.net.labate.me -u wiki -p wiki > dump-wiki.sql
+# This might take some time..
+```
+
+Second, restore it to the container. Note that the `wikì` database should already be created so you have to ̀`use` it.
+
+```
+# We will first copy the dump into the container
+docker cp dump-wiki.sql tools-compose_mariadb-wiki_1:/
+
+# Then start restore the file into the db
+docker exec -it tools-compose_mariadb-wiki_1 bash -c 'mysql -u root -p wiki < /dump-wiki.sql' 
+# Give the WIKI_DB_ROOT_PASSWORD as password
+
+# If it worked, we can delete the file from the container
+docker exec -it tools-compose_mariadb-wiki_1 rm /dump-wiki.sql
+```
+
+Third, we also need to restore images from the current server
+
+```
+# In my case I will use direct rsync, but we don't care about the method, we only need to copy them
+# take /var/www/main/(fr|en)/images content and put it into ./volumes/wiki-(fr|en)-images
+rsync -vr old-pc-wiki.net.labate.me:/var/www/main/fr/images/ ./volumes/wiki-fr-images/
+rsync -vr old-pc-wiki.net.labate.me:/var/www/main/en/images/ ./volumes/wiki-en-images/
+```
+
+Once everything has been copied, restart the `docker-compose up` to fix permissions on images directories.
+
+We can also ask MediaWiki to purge caches for all pages
+
+```
+docker exec -it tools-compose_phpfpm-wiki_1 php /www/wiki/fr/maintenance/purgeList.php --purge --all
+docker exec -it tools-compose_phpfpm-wiki_1 php /www/wiki/en/maintenance/purgeList.php --purge --all
