Payment Service

This sample Flogo application is used to demonstrate some key Flogo constructs:

  • Input/Output mappings
  • Complex object mapping


├── Dockerfile           <-- A Dockerfile to build a container based on an Alpine base image
├── Makefile             <-- A Makefile to help build and deploy the app
├── payment-svc.yml      <-- The Kubernetes deployment file
├── paymentservice.json  <-- The Flogo app
├── README.md            <-- This file

Make targets

The Makefile has a few targets:

  • clean: Remove the dist folder for a new deployment
  • clean-kube: Remove all the deployed artifacts from Kubernetes
  • build-app: Build an executable (both in Linux format as well as the native format of the current OS)
  • build-docker: Build a Docker container
  • run-docker: Run the Docker image with default settings
  • run-kube: Deploy the app to Kubernetes

For more detailed information on the commands that are executed you can check out the Makefile


After starting the app, it will register one endpoints:

  • /api/expected-date/:invoiceId: Generate a random payment date for an invoice

Building the app

To build via the Flogo CLI, simply download the paymentservice.json to your local machine and create the app structure:

flogo create -f paymentservice.json paymentservice
cd paymentservice

Now you can simply build the application and leverage the HTTP REST trigger as the entry point:

flogo build -e

The -e switch indicates that the binary should embed the flogo.json.

Run the application

Now that the application has been built, run the application:

cd bin
export HTTPPORT=9998

Test the application by opening your browser or via CURL and getting the following URL: http://localhost:9998/api/expected-date/1234

The following result should appear:


Importing into Flogo Web

If you want to import this flow into Flogo Web, please note there is a this is a current limitation in Flogo Web that it doesn't automatically import activities you do not have installed yet. To workaround this you can open an existing flow (or create a new flow) and import the activities using the "Install new activity" button. For this app you'll need to install:

Nothing but Go?
