+## Update
+
+When update a docker, you need to update the list of module.
+
+Run script to update configuration :
+```bash
+./script/docker/docker_gen_config.sh
+```
+
+Edit the docker-compose.yml and update the command line (change DATABASE) to :
+```yaml
+    command: odoo --workers 2 -u erplibre_info -d DATABASE
+```
+
+Note, the goal is to call `env['ir.module.module'].update_list()`.
+
+Restart the docker :
+```bash
+docker-compose down
+docker-compose up -d
+```
+
+Revert the command in docker-compose.yml.
+
+You can validate in log the update, you need to find `odoo.modules.loading: updating modules list`, check
+```bash
+docker-compose logs -f
+```
