Workflow Engine deployment in Kubernetes with Helm Charts

The Workflow Engine is a component that is responsible for executing the business processes that you create in the Business Studio. It is a lightweight, stateless, and horizontally scalable service that is responsible for handling the execution of the business processes.

This guide will walk you through deploying the Workflow Engine in a Kubernetes cluster using Helm charts.

Prerequisites

Before you begin, ensure you have the following:

• A Kubernetes cluster with kubectl configured to manage the cluster.
• Helm installed on your local machine.
• A configured Helm repository for the Platform Helm charts.

Deploy the Workflow Engine

1. Add the Platform Helm repository to your Helm installation:

   helm repo add platform https://platform.sh/helm-charts

2. Update the Helm repository to ensure you have the latest version of the Platform Helm charts:

    helm repo update

3. Deploy the Workflow Engine using the Helm chart:

4. Create a values.yaml file with the following content:

   workflowEngine:
     image:
       repository: platformsh/workflow-engine
       tag: 2.0.0
     service:
       type: ClusterIP
       port: 8080
     env:
       - name: PLATFORM_CONFIG_SERVER_URL
         value: "http://config-server:8888"
       - name: PLATFORM_CONFIG_SERVER_USERNAME
         value: "config-server"
       - name: PLATFORM_CONFIG_SERVER_PASSWORD
         value: "config-server"
