2.5.3. 创建机器集

流程

1. 创建一个包含机器集自定义资源（CR）示例的新 YAML 文件，并将其命名为 <file_name>.yaml。

   确保设置 <clusterID> 和 <role> 参数值。

   1. 如果您不确定要为特定字段设置哪个值，您可以从集群中检查现有机器集：

      $ oc get machinesets -n openshift-machine-api

      Copy to Clipboard Toggle word wrap

      输出示例

      NAME                                DESIRED   CURRENT   READY   AVAILABLE   AGE
      agl030519-vplxk-worker-us-east-1a   1         1         1       1           55m
      agl030519-vplxk-worker-us-east-1b   1         1         1       1           55m
      agl030519-vplxk-worker-us-east-1c   1         1         1       1           55m
      agl030519-vplxk-worker-us-east-1d   0         0                             55m
      agl030519-vplxk-worker-us-east-1e   0         0                             55m
      agl030519-vplxk-worker-us-east-1f   0         0                             55m

      Copy to Clipboard Toggle word wrap

   2. 检查特定机器集的值：

      $ oc get machineset <machineset_name> -n \
           openshift-machine-api -o yaml

      Copy to Clipboard Toggle word wrap

      输出示例

      ...
      template:
          metadata:
            labels:
              machine.openshift.io/cluster-api-cluster: agl030519-vplxk 

      1

      
              machine.openshift.io/cluster-api-machine-role: worker 

      2

      
              machine.openshift.io/cluster-api-machine-type: worker
              machine.openshift.io/cluster-api-machineset: agl030519-vplxk-worker-us-east-1a

      1

      集群 ID。

      2

      默认节点标签。

2. 创建新的 MachineSet CR:

   $ oc create -f <file_name>.yaml

3. 查看机器集列表：

   $ oc get machineset -n openshift-machine-api

   Copy to Clipboard Toggle word wrap

   输出示例

   NAME                                DESIRED   CURRENT   READY   AVAILABLE   AGE
   agl030519-vplxk-infra-us-east-1a    1         1         1       1           11m
   agl030519-vplxk-worker-us-east-1a   1         1         1       1           55m
   agl030519-vplxk-worker-us-east-1b   1         1         1       1           55m
   agl030519-vplxk-worker-us-east-1c   1         1         1       1           55m
   agl030519-vplxk-worker-us-east-1d   0         0                             55m
   agl030519-vplxk-worker-us-east-1e   0         0                             55m
   agl030519-vplxk-worker-us-east-1f   0         0                             55m

   当新机器集可用时，DESIRED 和 CURRENT 的值会匹配。如果机器集不可用，请等待几分钟，然后再次运行命令。
