Requirements

• Java 1.8
• Golang 1.5+
• Zeebe 0.5
• Running Zeebe broker
• zbctl

Setup

First create topic which will be used by our process.

zbctl create topic --name default-topic --partitions 1

then create workflow on the broker.

zbctl create workflow process.bpmn

To start microservices use make command. Open 3 terminals and in each of them start 1 service with the following commands:

make board

After starting this service, point your browser to http://localhost:5000 and click on the upload photo button. Select some PNG photo and confirm the upload.
