In addition to deploying the Orchestrator, we provide several preconfigured workflows that serve either as ready-to-use solutions or as starting points for customizing workflows according to the user’s requirements. These workflows can be installed either through a Helm chart or by utilizing Kustomize.
1 - Deploy From Helm Repository
Orchestrator Workflows Helm Repository
This repository serves as a Helm chart repository for deploying serverless workflows with the Sonataflow Operator. It encompasses a collection of pre-defined workflows, each tailored to specific use cases. These workflows have undergone thorough testing and validation through Continuous Integration (CI) processes and are organized according to their chart versions.
The repository includes a variety of serverless workflows, such as:
- Greeting: A basic example workflow to demonstrate functionality.
- Migration Toolkit for Application Analysis (MTA): This workflow evaluates applications to determine potential risks and the associated costs of containerizing the applications.
- Move2Kube: Designed to facilitate the transition of an application to Kubernetes (K8s) environments.
Usage
Prerequisites
To utilize the workflows contained in this repository, the Orchestrator Deployment must be installed on your OpenShift Container Platform (OCP) cluster. For detailed instructions on installing the Orchestrator, please visit the Orchestrator Helm Repository
Note With the existing version of the Orchestrator helm chart, all workflows should be created under the sonataflow-infra namespace.
Installation
helm repo add orchestrator-workflows https://parodos.dev/serverless-workflows-config
View available workflows on the Helm repository:
helm search repo orchestrator-workflows
The expected result should look like (with different versions):
NAME CHART VERSION APP VERSION DESCRIPTION
orchestrator-workflows/greeting 0.4.2 1.16.0 A Helm chart for the greeting serverless workflow
orchestrator-workflows/move2kube 0.2.16 1.16.0 A Helm chart to deploy the move2kube workflow.
orchestrator-workflows/mta 0.2.16 1.16.0 A Helm chart for MTA serverless workflow
orchestrator-workflows/workflows 0.2.24 1.16.0 A Helm chart for serverless workflows
You can install each workflow separately. For detailed information, please visit the page of each workflow:
Installing workflows in additional namespaces
When deploying a workflow in a namespace different from where Sonataflow services are running (e.g. sonataflow-infra), there are essential steps to follow. For detailed instructions, see the Additional Workflow Namespaces section.
Version Compatability
The workflows rely on components included in the Orchestrator chart. Therefore, it is crucial to match the workflow version with the corresponding Orchestrator version that supports it. The list below outlines the compatibility between the workflows and Orchestrator versions:
| Workflows | Chart Version | Orchestrator Chart Version |
|---|---|---|
| mta-analysis | 0.2.x | 1.0.x |
| mta-analysis | 0.3.x | 1.2.x |
| move2kube | 0.2.x | 1.0.x |
| move2kube | 0.3.x | 1.2.x |
| create-ocp-project | 0.1.x | 1.2.x |
| request-vm-cnv | 0.1.x | 1.2.x |
| modify-vm-resources | 0.1.x | 1.2.x |
| mta-v6 | 0.2.x | 1.2.x |
| mta-v7 | 0.2.x | 1.2.x |
| mtv-migration | 0.0.x | 1.2.x |
| mtv-plan | 0.0.x | 1.2.x |

2 - Deploy From Kustomize
Deploy workflows by Kustomize
The workflows can be deployed by Kustomize.
Under each workflow folder, there is a README file with detailed instructions on how to install the workflow separately.
