2.3.2. GCP 上机器设置自定义资源的 YAML 示例

此 YAML 示例定义了一个在 Google Cloud Platform (GCP) 中运行的机器集,并创建通过 node-role.kubernetes.io/<role>: "" 标记的节点。

在本例中,<infrastructure_id> 是基础架构 ID 标签,该标签基于您在置备集群时设定的集群 ID,而 <role> 则是要添加的节点标签。

指定基于置备集群时所设置的集群 ID 的基础架构 ID。如果已安装 OpenShift CLI,您可以通过运行以下命令来获取基础架构 ID:
$ oc get -o jsonpath='{.status.infrastructureName}{"\n"}' infrastructure cluster

指定要添加的节点标签。

指定当前机器集中使用的镜像的路径。如果已安装 OpenShift CLI,您可以通过运行以下命令来获取镜像的路径:
$ oc -n openshift-machine-api \
    -o jsonpath='{.spec.template.spec.providerSpec.value.disks[0].image}{"\n"}' \
    get machineset/<infrastructure_id>-worker-a
