<commit_before>Web UI
======

st2web is an Angular-based web application. It allows you to control the whole process of execution, from running an action to seeing the results of the execution. It also helps you to explore workflow executions up to the results of individual tasks. All in real time.

Express installation
--------------------

Production version of st2web is pre-installed on st2express and any other st2_deploy installation. You can access the UI by pointing your browser to ``http://<server hostname>:8080/``. For vagrant deployment of st2express, it would be http://172.16.17.32:8080/.

.. note::

    If you want to change the default listen port you can do that by setting the ``WEBUI_PORT``
    environment variable when controlling the services using the st2ctl script.

    For example, to make the WebUI HTTP server listen on port 9999, you would run the following
    command: ``WEBUI_PORT=9999 st2ctl restart``

Production version of st2web is pre-installed on st2express and any other st2_deploy installation. You can access the UI by pointing your browser to ``http://<server hostname>:8080/``. For vagrant deployment of st2express, it would be http://172.16.17.32:8080/.
