+### Local configuration
+Only nginx service is exposed with basic authentification required. WebAPI is access through Nginx with reverse proxy (default.conf):   
+```
+    location /WebAPI {
+        proxy_set_header Accept-Encoding "";
+        proxy_pass http://webapitomcat:8080;
+    } 
+```
+Our config-local.js file looks like this:
+
+```js
+define([], function () {
+	var configLocal = {};
+
+	configLocal.api = {
+		name: 'EDS CHU Bordeaux',
+		url: 'http://{HOSTNAME}:{NGINX_PORT}/WebAPI/'
+	};
+	return configLocal;
+});
+```
+where  
+* {HOSTNAME} is the name of the server where the docker-compose services are deployed 
+* {NGINX_PORT} is the NGINX port set in the .env file
+
+move this configuration file to the Atlas folder:
+```bash
+npm run build
+tar -zcf atlas.tar.gz *
+sudo mv atlas.tar.gz ../atlas/ # move it to the nginx volume 
+cd ../atlas/
+sudo tar -xf atlas.tar.gz  # deploy  
+```
