Host-based installation

This article describes how to install Kubernetes(RKE2) cluster and Rainbond cluster through graphical interface on Linux system.

tip

This installation method supports Linux x86 and Arm64 operating systems.

Prerequisites

• Ensure your environment meets the RKE2 installation requirements. If NetworkManager is installed and enabled on your host, pleaseensure it is configured to ignore CNI managed interfaces.
• If the host kernel supports AppArmor, you must also have AppArmor tools (usually available through the apparmor-parser package) before installation.
• The installation must be performed as the root user.

danger

If you have already performedquick installation, you cannot perform host-based installation on the same host again, as this will cause conflicts.

2. After filling in the configuration information, enter the Rainbond cluster installation page. On this page, you can see the installation progress information, and each component can be clicked to view the status and event information.
3. Wait for all components to start, then complete the docking in the next step.

If you are familiar with Kubectl commands, you can use the kubectl get pods -n rbd-system command to view the cluster status.

export KUBECONFIG=/etc/rancher/rke2/rke2.yaml
/var/lib/rancher/rke2/bin/kubectl get nodes

Next step

• Complete thequick start tutorial.
• Migrate theconsole to the Kubernetes cluster.
