+# Access a container configuration and persistent data
+
+Users with a VNC container in production have a dedicated `/home/VNC/prod/<username>` folder on the server.
+
+This folder mainly contain the  `docker-compose.yml` and `.env` files for a specific user.
+Those files describe and configure all the remote desktop environment for a specific user.
+
+Container persistent data is stored in a *Docker named volume*. The name of the volume is self explanatory and contain the user name.
+
+Data on the name volume are accessible in `/var/lib/docker/volumes/<volume_name>/_data/`, **do not write directlry on this directory**
+
+For details on how to list and access Docker volumes from the host, please refer to the [Docker volumes official documentation](https://docs.docker.com/engine/reference/commandline/volume/).
+
+# Restart a container
+
+To restart a user container :
+1.  Go to the `/home/VNC/prod/<username>` folder on the server
+2 Run the following (needs to be in the `docker` group or root priviledges) :
+`docker-compose down` (wait for the command to finish, it can take seconds)
+`docker-compose up -d`
+
+Container restart should be necessary in two cases only :
+1. The container needs to be upgraded
+2. The container became irresponsive or crashed
+
+In the second case, please run the following command BEFORE restarting the container, and contact contact@tetras-libre.fr :
+```bash
+docker-compose logs > lastLogs
+```
