以下是运行 bmctl create cluster 命令时创建的 YAML 文件的示例。如需详细了解此命令以及如何使用它来创建不同类型的集群配置，请参阅以下主题：

# bmctl configuration variables. Because this section is valid YAML but not a valid Kubernetes
# resource, this section can only be included when using bmctl to
# create the initial admin/hybrid cluster. Afterwards, when creating user clusters by directly
# applying the cluster and node pool resources to the existing cluster, you must remove this
# section.

# Cluster type. This can be:
# 1) admin: to create an admin cluster. This can later be used to create user clusters.
# 2) user: to create a user cluster. Requires an existing admin cluster.
# 3) hybrid: to create a hybrid cluster that runs admin cluster components and user workloads.
# 4) standalone: to create a cluster that manages itself, runs user workloads, but does not manage other clusters.

# Load balancer configuration
loadBalancer:
# Load balancer mode can be either 'bundled' or 'manual'.
# In 'bundled' mode a load balancer will be installed on load balancer nodes during cluster creation.
# In 'manual' mode the cluster relies on a manually-configured external load balancer.
mode: bundled
# Load balancer port configuration
ports:
# Specifies the port the load balancer serves the Kubernetes control plane on.
# In 'manual' mode the external load balancer must be listening on this port.
controlPlaneLBPort: 443
# There are two load balancer VIPs: one for the control plane and one for the L7 Ingress
# service. The VIPs must be in the same subnet as the load balancer nodes.
vips:
# ControlPlaneVIP specifies the VIP to connect to the Kubernetes API server.
# This address must not be in the address pools below.
controlPlaneVIP: 10.0.0.8
# IngressVIP specifies the VIP shared by all services for ingress traffic.
# Allowed only in non-admin clusters.
# This address must be in the address pools below.
# ingressVIP: 10.0.0.2
# AddressPools is a list of non-overlapping IP ranges for the data plane load balancer.
# All addresses must be in the same subnet as the load balancer nodes.
# Address pool configuration is only valid for 'bundled' LB mode in non-admin clusters.

# A load balancer node pool can be configured to specify nodes used for load balancing.
# These nodes are part of the Kubernetes cluster and run regular workloads as well as load balancers.

# path specifies the host machine path where subdirectories will be created on each host. A local PV
# will be created for each subdirectory.

# Authentication; uncomment this section if you wish to enable authentication to the cluster with OpenID Connect.
