1.7. 创建集群
了解如何使用 Red Hat Advanced Cluster Management for Kubernetes 跨云供应商创建 Red Hat OpenShift Container Platform 集群。
1.7.1. 在集群创建过程中配置额外清单
您可以在创建集群的过程中配置额外的 Kubernetes 资源清单。如果您需要为配置网络或设置负载均衡器等场景配置额外清单，这可以提供帮助。
在创建集群前，您需要添加对 ClusterDeployment 资源的引用，该资源指定包含其他资源清单的 ConfigMap。
注： ClusterDeployment 资源和 ConfigMap 必须位于同一命名空间中。以下示例演示了您的内容看起来如何。
带有资源清单的 ConfigMap
包含具有另一个
ConfigMap资源的清单的ConfigMap。资源清单ConfigMap可以包含多个键，并在data.<resource_name>\.yaml模式中添加资源配置。kind: ConfigMap apiVersion: v1 metadata: name: <my-baremetal-cluster-install-manifests> namespace: <mynamespace> data: 99_metal3-config.yaml: | kind: ConfigMap apiVersion: v1 metadata: name: metal3-config namespace: openshift-machine-api data: http_port: "6180" provisioning_interface: "enp1s0" provisioning_ip: "172.00.0.3/24" dhcp_range: "172.00.0.10,172.00.0.100" deploy_kernel_url: "http://172.00.0.3:6180/images/ironic-python-agent.kernel" deploy_ramdisk_url: "http://172.00.0.3:6180/images/ironic-python-agent.initramfs" ironic_endpoint: "http://172.00.0.3:6385/v1/" ironic_inspector_endpoint: "http://172.00.0.3:5150/v1/" cache_url: "http://192.168.111.1/images" rhcos_image_url: "https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911192044.0/x86_64/rhcos-43.81.201911192044.0-openstack.x86_64.qcow2.gz"使用引用的资源清单
ConfigMap的 ClusterDeployment资源清单
