Overview
Use the Install section to plan and complete Core installation.
Core installation deploys the global cluster, which provides the platform management plane for web console access, cluster management, users and roles, and extension management. For the platform architecture and definitions of global cluster and workload cluster, see Architecture and Glossary.
Core installation does not create workload clusters, import existing clusters, or install Extensions Packages. Operators and Cluster Plugins that are delivered as Extensions are installed after Core through the Extend workflow.
Core installation does not support direct installation of the global cluster into an existing Kubernetes environment. Prepare new nodes that meet the hardware, network, storage, and OS requirements before you start installation.
Installation Scope
Core installation provides the foundation for the platform management plane. After Core is installed and verified, you can create or connect workload clusters and install Extensions according to your platform scenario.
The procedure described in this section installs the global cluster onto a traditional operating system such as Ubuntu or RHEL. If you want the global cluster to run on Immutable Infrastructure (MicroOS on Huawei DCS, VMware vSphere, or Huawei Cloud Stack), see Installing the global Cluster on Immutable Infrastructure instead.
The following work is outside the Core installation flow:
- Creating workload clusters.
- Connecting existing Kubernetes clusters.
- Uploading and installing Extensions Packages.
- Installing Operators or Cluster Plugins that are delivered as Extensions.
- Configuring optional platform capabilities such as storage, monitoring, backup, registry, or identity integrations.
Installation Workflow
Core installation follows this high-level path:
- Plan. Choose the deployment architecture and confirm install-time decisions.
- Prepare for installation. Prepare resources, network access, storage, and nodes.
- Download. Obtain the official Core Package from the Customer Portal.
- Installing. Upload the Core Package, start the installer, and configure installation parameters.
- Validation. Confirm that the platform Web UI, core applications, and Pods are healthy.
- Next Steps. Install the Product Docs plugin and follow scenario-based next steps.
The Customer Portal is the official source for installation packages. For download requirements and package architecture options, see Download.
If you have already downloaded Extensions Packages, install Core first. Upload and install Extensions Packages only after Core installation is complete.
