Download the addon offline package. You can download the latest version from the Download Center (optional).

Set up the cluster configuration file clusterConfig.yaml. You can find this file in the offline/sample directory of the offline package and modify it as needed. The reference configuration is as follows:

apiVersion: provision.daocloud.io/v1alpha3
kind: ClusterConfig
metadata:
spec:
  clusterName: oracle-cluster
  loadBalancer:
    type: metallb
    istioGatewayVip: 172.30.41.XXX/32

  masterNodes:
    - nodeName: "g-master"
      ip: 172.30.41.XXX
      ansibleUser: "root"

    osPackagePath: "/root/workspace/os-pkgs/os-pkgs-oracle9-v0.5.4.tar.gz"
  imagesAndCharts:

  kubeanConfig: |-
    # Enable recommended sysctl settings to avoid 'too many open files' issues
    node_sysctl_tuning: true
    # Disable kubespray from installing public repo for Oracle Linux
    use_oracle_public_repo: false

Note

Due to an error with the kpanda-controller-manager component during installation, stating failed to create fsnotify watcher: too many open files., it is necessary to set node_sysctl_tuning: true in the clusterConfig.yaml file.

Start the installation of DCE 5.0.
```
./dce5-installer cluster-create -m ./sample/manifest.yaml -c ./sample/clusterConfig.yaml
```
Note

Here are some parameter introductions. You can refer to ./dce5-installer --help for more parameters:
- -z: Minimal installation
- -c: Specify the cluster configuration file (not required when exposing the console using NodePort)
- -d: Enable debug mode
- --serial: Run all installation tasks in a serial manner
After the installation is complete, the command line will prompt for a successful installation. Congratulations! 🎉 Now you can explore the brand new DCE 5.0 using the default account and password (admin/changeme) provided in the URL shown on the screen.
