Publishing ESB artifacts to a distant Docker registry

Before you begin

Make sure that a Docker registry is configured in your artifact repository (Nexus, Artifactory).

Procedure

Open a command prompt or terminal and execute the following command to build and deploy artifacts on a distant Nexus Docker registry.

$ mvn -Dgeneration.type=local -Dproduct.path=<STUDIO_HOME> -s <STUDIO_HOME>/configuration/maven_settings.xml \
						deploy -Pdocker \
						-f <GIT_PROJECT_PATH>/<STUDIO_PROJECT>/poms \
						-pl jobs/process/demorest_0.1,jobs/routes/demorestroute_0.1,jobs/routes/directsedademo_0.1 \
						-Ddocker.push.username=<username> -Ddocker.push.password=<password> -Ddocker.push.registry=<ARTIFACT_REPOSITORY_HOST>:<DOCKER_REGISTRY_PORT>

where

<STUDIO_HOME> corresponds to the Talend Studio installation path
<GIT_PROJECT_PATH> corresponds to the path of your Git project or Git clone result
<STUDIO_PROJECT> corresponds to the Talend Studio project name that is the same as the Git project name. Project names must be in upper case.
<ARTIFACT_REPOSITORY_HOST> corresponds to the host of the artifact repository (Nexus, Artifactory)
<ARTIFACT_REPOSITORY_DOCKER_REGISTRY> corresponds to the host of the URL of the artifact repository Docker registry (Nexus, Artifactory)
<DOCKER_REGISTRY_PORT> corresponds to the port binded for accessing the Docker repository (specific to Nexus)

Tip: Use the -Dstudio.prometheus.metrics=true command while publishing to Docker in order to expose Camel metrics to Prometheus and provide more details about the deployed Routes (number of processed exchanges, number of errors, requests per seconds, etc).

Connect to the Docker Registry and pull from the distant Docker registry to the local Docker registry.
