Building a Data Service Job as a Microservice Docker image

About this task

This feature is not shipped with Talend Studio by default. You need to install it using the Feature Manager. For more information, see Installing features using the Feature Manager.

In the Build Job dialog box, you can build a Data Service Job as a Microservice Docker image in order to execute it on a Docker engine.
Information noteWarning: Only Jobs that include the tRESTRequest component can be built as a Microservice Docker image.

Procedure

  1. Open the Job that you want to build as a Microservice in the design work space. In the Deployment view of the Job tab, select Microservice from the Build Type list. Save the Job.
    Select the Microservice build type.
  2. In the Repository tree view, right-click the Job you want to build, and select Build Job to open the dialog box.
    Build the Job as a Microservice Docker Image.
  3. In the Job Version area, select the Data Service Job you want to build if you have created more than one version of the Job.
  4. In the Build type area, select Microservice as Docker image to build your Job as a Microservice Docker image.
  5. In the options area, select the Enable Prometheus metrics endpoint check box to build the Prometheus metrics endpoint into the Microservice to monitor the execution of Jobs, JVM memory, CPU consumption, and so on. By default, this feature bridges all the JMX attributes and values into Prometheus. For more information about Prometheus, see the Prometheus documentation.
  6. In the Docker Options area, select Local or specify a remote address based on your Docker engine installation.
    Information noteWarning: If you select the Remote option, make sure that Docker deamon is started with a remote port.
  7. Specify your Docker image name, and image tag.
    By default, the image name is derived from the project name and Job name, and the image tag is derived from the version of the Job. You can specify a new name and tag here or customize the default settings globally in Project Settings. For more information, see Customizing Docker images build settings.
    Information noteWarning: Underscore characters are not supported in Docker image names, therefore make sure the Docker image name value does not contain underscore characters.
  8. Click Finish to build your Microservice Docker image.

Results

You Job is build as a Microservice Docker image and ready to run on your Docker engine.
