12.2.11. 设置计算机器关联性

流程

1. 使用 RHOSP 命令行界面，为您的计算机器创建服务器组。例如：

   $ openstack \
       --os-compute-api-version=2.15 \
       server group create \
       --policy anti-affinity \
       my-openshift-worker-group

   Copy to Clipboard Toggle word wrap

   如需更多信息，请参阅服务器组 create 命令文档。

2. 进入包含安装程序的目录并创建清单：

   $ ./openshift-install create manifests --dir=<installation_directory>

   Copy to Clipboard Toggle word wrap

   其中：

   installation_directory

   指定包含集群的 install-config.yaml 文件的目录名称。

3. 打开 manifests/99_openshift-cluster-api_worker-machineset-0.yaml，这是 MachineSet 定义文件。

4. 将属性 serverGroupID 添加到 spec.template.spec.providerSpec.value 属性下的定义中。例如：

   apiVersion: machine.openshift.io/v1beta1
   kind: MachineSet
   metadata:
     labels:
       machine.openshift.io/cluster-api-cluster: <infrastructure_ID>
       machine.openshift.io/cluster-api-machine-role: <node_role>
       machine.openshift.io/cluster-api-machine-type: <node_role>
     name: <infrastructure_ID>-<node_role>
     namespace: openshift-machine-api
   spec:
     replicas: <number_of_replicas>
     selector:
       matchLabels:
         machine.openshift.io/cluster-api-cluster: <infrastructure_ID>
         machine.openshift.io/cluster-api-machineset: <infrastructure_ID>-<node_role>
     template:
       metadata:
         labels:
           machine.openshift.io/cluster-api-cluster: <infrastructure_ID>
           machine.openshift.io/cluster-api-machine-role: <node_role>
           machine.openshift.io/cluster-api-machine-type: <node_role>
           machine.openshift.io/cluster-api-machineset: <infrastructure_ID>-<node_role>
       spec:
         providerSpec:
           value:
             apiVersion: openstackproviderconfig.openshift.io/v1alpha1
             cloudName: openstack
             cloudsSecret:
               name: openstack-cloud-credentials
               namespace: openshift-machine-api
             flavor: <nova_flavor>
             image: <glance_image_name_or_location>
             serverGroupID: aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee

             kind: OpenstackProviderSpec
             networks:
             - filter: {}
               subnets:
               - filter:
                   name: <subnet_name>
                   tags: openshiftClusterID=<infrastructure_ID>
             securityGroups:
             - filter: {}
               name: <infrastructure_ID>-<node_role>
             serverMetadata:
               Name: <infrastructure_ID>-<node_role>
               openshiftClusterID: <infrastructure_ID>
             tags:
             - openshiftClusterID=<infrastructure_ID>
             trunk: true
             userDataSecret:
               name: <node_role>-user-data
             availabilityZone: <optional_openstack_availability_zone>

   在此处添加服务器组的 UUID。

5. 可选：备份 manifests/99_openshift-cluster-api_worker-machineset-0.yaml 文件。创建集群时，安装程序会删除 manifests/ 目录。
