clusterConfig.yaml

This YAML file contains various configuration fields of the cluster, and this file must be configured before installation. This file will define key parameters such as deployment mode and cluster node information. By default it is located in the offline/sample/ directory.

ClusterConfig Example

The following is an example of ClusterConfig.yaml.

clusterConfig.yaml

kind: ClusterConfig
metadata:
spec:
  clusterName: my-cluster

  # The domain name or IP address of the bootstrap node, by default resolves to the IP of the default gateway on the bootstrap node's network interface. You can manually enter an IP or domain name. If it is a domain name and unable to be resolved, an automatic mapping will be created between this domain name and the default IP of the bootstrap node.

Simplified configuration instructions

In the offline mode, use the builtin method to install

The builtin mode means that the required third-party software (such as ChartMuseum, Minio, Docker registry) will be deployed and provided by the installer for use in the DCE 5.0 platform.

Installation in external mode in offline mode

The external mode means that the required third-party software (such as ChartMuseum, Minio, Docker registry, etc.) does not need to be installed by the installer. Instead, the user provides the addresses for these services to be used by the DCE 5.0 platform.
