 	"description": "",
-	"content": " Hono can be deployed using the pre-built Docker images available from our Docker Hub repositories. However, customizing and/or extending Hono\u0026rsquo;s functionality requires building the images from source code.\nThis page provides step by step instructions for getting the source code and building the Hono\u0026rsquo;s Docker images from it.\nPrerequisites for building Hono Docker Creating Hono\u0026rsquo;s container images using the Hono build process requires a Docker daemon running either locally or on another host you have access to. Please follow the instructions on the Docker web site to install Docker on your platform.\nJava Hono is written in Java and therefore requires a Java Development Kit (JDK) version 11 or higher installed on your computer. Please follow the JDK vendor\u0026rsquo;s instructions for installing Java on your operating system.\nMaven Hono\u0026rsquo;s build process is based on Apache Maven. You need at least Maven 3.5 in order to build Hono. Please follow the installation instructions on the Maven home page.\nGit A Git client is required if you want to contribute changes/improvements to the Hono project. It is not necessary for simply building Hono locally. Please refer to the Git Downloads page for installation instructions.\nGetting the Hono Source Code Either\n download the latest release archive and extract the archive to a local folder or clone the Hono source code repository from GitHub:\ngit clone https://github.com/eclipse/hono.git  This will create a hono folder in the current working directory and clone the whole repository into that folder.\n  Starting the Hono Build Process Run the following from the source folder:\n# in the \u0026quot;hono\u0026quot; folder containing the source code mvn clean install -Ddocker.host=tcp://${host}:${port} -Pbuild-docker-image,metrics-prometheus,jaeger  with ${host} and ${port} reflecting the name/IP address and port of the host where Docker is running on. This will build all libraries, Docker images and example code. If you are running on Linux and Docker is installed locally or you have set the DOCKER_HOST environment variable, you can omit the -Ddocker.host property definition.\nIf you plan to build the Docker images more frequently, e.g. because you want to extend or improve the Hono code, then you should define the docker.host property in your Maven settings.xml file containing the very same value as you would use on the command line as indicated above. The file is usually located in the .m2 folder in your user\u0026rsquo;s home directory. This way you can simply do a mvn clean install later on and the Docker images will be built automatically as well because the build-docker-image profile is activated automatically if the Maven property docker.host is set.\n Be patient The first build might take several minutes because Docker will need to download all the base images that Hono is relying on. However, most of these will be cached by Docker so that subsequent builds will be running much faster.  Using custom Image Names The container images being created will have names based on the following pattern: ${docker.registry-name}/${docker.image.org-name}/${project.artifactId}:${project.version}.\nThe variables in the name are standard Maven properties. The default value for the docker.registry-name property is index.docker.io. The default value for docker.image.org-name is eclipse. The following build command creates Hono\u0026rsquo;s images using the quay.io registry and the custom repository name:\nmvn clean install -Ddocker.host=tcp://${host}:${port} -Pbuild-docker-image,metrics-prometheus,jaeger -Ddocker.registry-name=quay.io -Ddocker.image.org-name=custom  Building native Images The build process supports building native Docker images using the GraalVM for some of Hono\u0026rsquo;s components. In order to do so, the build-native-image Maven profile needs to be activated:\n# in the \u0026quot;hono\u0026quot; folder containing the source code mvn clean install -Ddocker.host=tcp://${host}:${port} -Pbuild-native-image,metrics-prometheus   Experimental Support for native images is an experimental feature. The build-native-image and the build-docker-image profiles are mutually exclusive. Using Jaeger tracing with native images doesn\u0026rsquo;t work yet, i.e. the jaeger Maven profile must not be activated when building native images.  Pushing Images The container images that are created as part of the build process can be automatically pushed to a container registry using the docker-push-image Maven profile:\nmvn clean install -Ddocker.host=tcp://${host}:${port} -Pbuild-docker-image,metrics-prometheus,jaeger,docker-push-image  Note that the container registry might require authentication in order to push images. The build uses the Docker Maven Plugin for creating and pushing images. Please refer to the plugin documentation for details regarding how to configure credentials for the registry.\nPerform the integration tests The source code for Hono comes with a test suite for integration testing. To trigger these tests, change to the tests folder and execute:\n# in the \u0026quot;hono/tests\u0026quot; folder containing the test suite mvn verify -Prun-tests  The tests are executed against the Docker images of the Hono components. Because of that, it is necessary to build the respective images as described above before the execution of the tests. The respective Readme.md file in the folder hono/tests contains more information regarding the test suite.\n"

However, most of these will be cached by Docker so that subsequent builds will be running much faster.  Gathering Code Coverage Information for Unit Tests Hono\u0026rsquo;s unit tests can be configured to gather code coverage information during execution using the JaCoCo Maven plugin. The plugin is disabled by default and can be enabled by setting the jacoco.skip maven property to false:\n# in the \u0026quot;hono\u0026quot; folder containing the source code mvn clean install -Djacoco.skip=false -Ddocker.host=tcp://${host}:${port} -Pbuild-docker-image,metrics-prometheus,jaeger  The plugin will produce a target/jacoco.exec file in each module which contains the (binary) coverage data. It will also produce XML data files under target/site/jacoco in each module. Tools like SonarQube can be used to collect and properly format this data.\nUsing custom Image Names The container images being created will have names based on the following pattern: ${docker.registry-name}/${docker.image.org-name}/${project.artifactId}:${project.version}.\nThe variables in the name are standard Maven properties. The default value for the docker.registry-name property is index.docker.io. The default value for docker.image.org-name is eclipse.
