|  | <description>Hono can be deployed using the pre-built Docker images available from our Docker Hub repositories. However, customizing and/or extending Hono&rsquo;s functionality requires building the images from source code. | 
|  | This page provides step by step instructions for getting the source code and building the Hono&rsquo;s Docker images from it. | 
|  | Prerequisites for building Hono Docker Creating Hono&rsquo;s container images using the Hono build process requires a Docker daemon running either locally or on another host you have access to.</description> |

|  | <description>To illustrate how Eclipse Hono&trade; can be integrated with Java code, a simple application is provided that consumes telemetry and event data for devices belonging to the default tenant. |

|  | if indicated by a received downstream message that contains a ttd value (refer to Device notifications for details) it tries to send a command to the device. If the value of ttd indicates that the device stays connected for an unlimited time (ttd == -1), the application will periodically repeat to send a command until notified the device is disconnected again (ttd == 0).</description> |
