1.17.2. 解决这个问题: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

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。

备注：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
spec:
  channel: release-2.1
  config:
    resources:
      limits:
        cpu: 750m
        memory: 2Gi
      requests:
        cpu: 150m
        memory: 128Mi
  installPlanApproval: Automatic
  name: multicluster-operators-subscription
  source: community-operators
  sourceNamespace: openshift-marketplace

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

apiVersion: v1
kind: Pod
