Containerization requirements and limitations

This section describes the requirements to deploy the HCL Digital Experience 9.5 images to container platforms and current limitations.

Attention

Beginning with HCL Digital Experience 9.5 Container Update CF200, HCL has discontinued releasing the HCL Digital Experience (DX) Operator-based deployments and will provide support only for Helm-based deployments. There will be no further updates or code fixes provided for the Operator-based deployments. HCL requires all customers to migrate to Helm-based deployments for their DX installations. HCL will work with our customers as they transition from Operator-based to Helm-based deployments. For more information on the migration process, see Migrating from Operator-based to Helm-based deployments.

Consult the HCL Digital Experience 9.5 Support Statements on the HCL DX Support pages for the latest updates on supported platforms, components, and release levels.

Requirements and limitations for Helm-based deployments

This section describes the requirements and limitations for HCL Digital Experience 9.5 Container Update CF200 and later deployments using Helm.

HCL DX 9.5 CF200 and later is designed to run on any certified Kubernetes platform (https://www.cncf.io/certification/software-conformance), provided that,

For the list of Kubernetes versions that are tested and supported by HCL, refer to the HCL DX supported hardware and software statements page.

Even though the platforms might be Certified Kubernetes platforms, you might find the environments varying slightly based on the vendors. HCL Support will make a reasonable effort to assist the customer in problem resolution in scenarios where the Kubernetes version is still under support by the vendor. If there are any unresolved issues, HCL Support will provide alternative implementation recommendations or open Feature Requests for the problem scenario.

Internally, HCL tests DX against a range of Kubernetes platforms that is regularly reviewed and updated. We do not test with every single platform vendor, but aim to cover a representative sample of popular Kubernetes implementations. See the HCL DX supported hardware and software statements on the HCL Support Knowledge Base for additional details.

To deploy HCL Digital Experience 9.5 CF200 to the supported Kubernetes platforms using Helm, the following are required:

  • Helm installation:

    Download and install Helm to your target environment. HCL DX 9.5 CF200 and later container deployment is tested and is supported with Helm v3. For more information regarding the supported Helm version for individual Kubernetes versions, refer Helm documentation.

  • Migration:

    For information about migrating from Operator-based to Helm-based deployments, see Migrating from Operator-based to Helm-based deployments.

  • Container platform capacity resource requirements:

    The following table outlines the minimal possible amount of resource requests by the HCL DX 9.5 Container Components in the Helm-based deployments, as well as the minimum of Pods required of each component. If you want to use this minimal configuration, adjust the resource requests in your custom-values.yaml accordingly. Please consider that every Kubernetes node requires some headroom for Kubernetes specific services. Ensure that your Kubernetes Node has enough capacity to host both the Kubernetes services as well as HCL DX. Please be aware that the overall requested amount of resources may vary based on disabled/enabled applications.
