要指定 OLM 部署 OpenShift Virtualization Operator 的节点，在 OpenShift Virtualization 安装过程中编辑 Subscription 对象。
目前，您无法使用 Web 控制台为 Subscription 对象配置节点放置规则。
Subscription 对象不支持 关联性 节点放置规则。
使用 nodeSelector 规则的 Subscription 对象示例
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
name: hco-operatorhub
namespace: openshift-cnv
spec:
source: redhat-operators
sourceNamespace: openshift-marketplace
name: kubevirt-hyperconverged
startingCSV: kubevirt-hyperconverged-operator.v4.17.43
channel: "stable"
config:
nodeSelector:
example.io/example-infra-key: example-infra-value
OLM 在带有 example.io/example-infra-key = example-infra-value 的节点上部署 OpenShift Virtualization Operator。
带有 tolerations 规则的 Subscription 对象示例
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
name: hco-operatorhub
namespace: openshift-cnv
spec:
source: redhat-operators
sourceNamespace: openshift-marketplace
name: kubevirt-hyperconverged
startingCSV: kubevirt-hyperconverged-operator.v4.17.43
channel: "stable"
config:
tolerations:
- key: "key"
operator: "Equal"
value: "virtualization"
effect: "NoSchedule"
OLM 在带有 key = virtualization:NoSchedule 污点的节点上部署 OpenShift Virtualization Operator。只有具有匹配容限的 pod 才会调度到这些节点上。
