Installing and upgrading
HCL™ Accelerate consists of services and other tools that are stored in Docker containers. A Docker container is a single unit that contains a software application, often called a service, and the environment needed to run it. Containers can be created and destroyed as needed.
HCL™ Accelerate consists of over 10 containers. Because of the number of containers, another application, called a container orchestrator, is used to manage the containers. Docker Compose is recommended for proof of concepts such as trials or test environments. For production environments, Kubernetes or another Kubernetes-based orchestrator, such as OpenShift, is only supported platform.
For Docker Compose installations, resources are defined in a file named
docker-compose.yml that is found in the installation folder. For
Kubernetes and Openshift installations, the resources are combined into a single file
called a Helm chart. You can change a resource by modifying the affected template file
or the corresponding resource in the Helm chart.
| Docker Compose | Kubernetes | |
|---|---|---|
| Product core configuration | 15 containers | 43 resources, 1 Helm chart |
| External communication | 13 exposed ports | Ingress for communication. NodePort exposed for external communication. |
| Storage | 4 volumes | None |
System requirements
System requirement is an initial setup required before starting the installation. For more information about system requirement, see this page
Docker Compose versus Kubernetes versus OpenShift platform support
HCL™ Accelerate installations on Docker Compose are not supported for production environments. The Docker Compose installation includes security and performance issues. The Docker Compose installation cannot control container runtimes and complex calculations, which impacts multiple UI components. For example, the random import of plug-ins impact the performance of product features, like the value stream, releases, and API response time.
Kubernetes installations using Helm provides good security and permissions. Kubernetes supports controlling the container runtime and manages complex calculations.
Considering the security and performance practices, use the Kubernetes and OpenShift platform installations for best results in production environments. For the supported version of Kubernetes and OpenShift platform, see system requirements.

Docker Compose is recommended only for proof of concept such as test or trial environments. Kubernetes or another Kubernetes-based orchestrator, such as OpenShift, is must for production environment.
