    ```bash
-   vendor/bin/ece-docker build:compose --mode --sync-engine="mutagen" developer --with-xdebug
+   vendor/bin/ece-docker build:compose --mode="developer" --sync-engine="mutagen" --with-xdebug

+      ```bash
+      vendor/bin/ece-docker build:compose --mode="developer" --with-xdebug --set-docker-host
+      ```
