Deploying HCL Commerce+ Transaction Server

This section provides details on deploying HCL Commerce+ Transaction Server. It explains how to download the Docker images and Git bundles that comprise the product, how to create a minimal environment, and how to plan for a full deployment. It details supported software versions, patches, and configurations to ensure the platform performs well.

A typical HCL Commerce+ Transaction Server deployment involves creating and testing a minimal environment before implementing a complete production environment. The deployment uses a combination of Git bundles and Docker containers. Helm charts control Kubernetes configurations during the deployment.

The minimal environment is a learning environment that uses basic versions of the systems your production environment will need. You deploy this minimal setup within a Kubernetes environment.
The production environment is specific to your business, and its exact setup is beyond the scope of this documentation. You will develop it according to your own needs in consultation with your stakeholders and technologists.
To customize HCL Commerce+ Transaction Server you can add a eXternalized Customization (xC) environment. You can use xC environments to build extensions to the default Commerce+ Transaction Server functionality. The Commerce+ Transaction Server Core integrates xC extensions as modules separate from their primary functions. You can easily and frequently update xC extensions without worrying about any core functionality being overwritten.

The following sections guide you through deploying these environments.
