+=======================
+Advanced Deploy Options
+=======================
+
+AppAPI allows optionally to configure environment variables and mounts for the ExApp container.
+
+It is available via "Deploy options" modal next to "Deploy and Enable" button in the sidebar of the ExApp page on the Apps management page:
+
+.. image:: ./img/advanced_deploy_options_1.png
+
+Or via CLI (:ref:`advanced_deploy_options_cli`).
+
+
+Environment Variables
+---------------------
+
+Environment variables enable more precise configuration of the ExApp.
+ExApp developers can define the list of supported environment variables with descriptions,
+only these variables will be available for configuration.
+
+By default there are only mounts available for configuration.
+

+.. image:: ./img/advanced_deploy_options_3.png
+
+When ExApp installed the list of set environment variables will be displayed.

+
+
+Mounts
+------
+
+Mounts can be used to provide additional data to the ExApp container from the host.
+For example, it will be useful for some apps to provide a folder with SSL certs of your cloud,
+so the app can handle HTTPS correctly without any additional re-installation of the ExApp.
