1.19.2. 解决问题：独立订阅内存

安装后，找到订阅 multicluster subscription community operator 的 operator 订阅 CR。运行以下命令：
```
% oc get sub -n open-cluster-management acm-operator-subscription
```
```
% oc get sub -n open-cluster-management acm-operator-subscription
```

编辑 operator 订阅自定义资源，添加 spec.config.resources.yaml 文件，以定义资源限值。

注：不要创建新的、订阅了同一个多集群订阅社区 operator 的订阅自定义资源。因为两个 operator 订阅都连接到一个 operator，operator Pod 会被 "killed" 并由两个 operator 订阅自定义资源重启。

请参阅以下更新的 .yaml 文件示例：

apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: multicluster-operators-subscription-alpha-community-operators-openshift-marketplace
  namespace: open-cluster-management

保存资源后，确保独立订阅 Pod 被重启为有 2GB 内存限制。运行以下命令：

% oc get pods -n open-cluster-management multicluster-operators-standalone-subscription-7c8cbf885f-c94kz -o yaml

% oc get pods -n open-cluster-management multicluster-operators-standalone-subscription-7c8cbf885f-c94kz -o yaml
