 Connect to external hosts
 *************************
 
-TODO
+
+Connecting from inside a Devilbox Docker container to any external host works out of the box.
+The only thing you need is internet/network access and know its hostname or IP address.
+
+Each container has internet access, thus you can ``curl``, ``fetch``, connect to or download
+any online resources from within the container.

 Docker Toolbox
 ==============

 Docker Toolbox behaves the same way as Docker on Linux, with one major difference.
 The Devilbox IP address or the custom provided CNAMEs actually refer to the Docker Toolbox machine.

 Connect to other Docker container
 *********************************
 
-TODO
+Other Docker container can either be accessed by connecting back to the host os or by adding its
+image directly to the Devilbox stack.

+Any Docker container on host os
+===============================
+
+1. To connect to any other Docker container on your host os from within the Devilbox Docker
+   container, you first need to make sure, you are able to connect to your host os from within the
+   Devilbox Docker container.
+
+   .. seealso:: :ref:`connect_to_host_os`
+
+2. Once you are able to connect to the host os, start any other Docker container and make its
+   port that you want to access available to your host os by specifying ``-p``.
+   An example with e.g. an external `Grafana <https://hub.docker.com/r/grafana/grafana/>`_ container
+   might look like this:
+
+   .. code-block:: bash
+
+      host> docker run -d --name=grafana -p 3000:3000 grafana/grafana
+
+   You can then connect to your host os on port ``3000`` from within the Devilbox Docker container
+   and be able to use it.
+
+
+Add Docker container to Devilbox stack
+======================================
+
+Alternatively you can also add any Docker container to the Devilbox network by adding an image
+it to the Devilbox stack directly.
