1.2.11.5. 现在支持 Operator API

流程

1. 因为 Operator API 标签自动应用于 OpenShift Container Platform 4.6 中的相关资源，所以您必须删除之前手动应用的所有 operators.coreos.com/<name> 标签。

   1. 您可以通过运行以下命令，检查当前为 Operator 标记了哪些资源，并查看 status.components.refs 部分：

      $ oc describe operator <operator_name>

      例如：

      $ oc describe operator etcd-test

      Copy to Clipboard Toggle word wrap

      输出示例

      ...
      Status:
        Components:
          Label Selector:
            Match Expressions:
              Key:       operators.coreos.com/etcd-test
              Operator:  Exists
          Refs:

      资源类型。

      2

      资源名称。

   2. 从所有相关资源中删除标签。例如：

      $ oc label sub etcd operators.coreos.com/etcd-test- -n test-project
      $ oc label ip install-6c5mr operators.coreos.com/etcd-test- -n test-project
      $ oc label csv etcdoperator.v0.9.4 operators.coreos.com/etcd-test- -n test-project
      $ oc label crd etcdclusters.etcd.database.coreos.com operators.coreos.com/etcd-test-
      $ oc label crd etcdbackups.etcd.database.coreos.com operators.coreos.com/etcd-test-
      $ oc label crd etcdrestores.etcd.database.coreos.com operators.coreos.com/etcd-test-

      Copy to Clipboard Toggle word wrap

2. 删除 Operator 自定义资源定义（CRD）：

   $ oc delete crd operators.operators.coreos.com

   Copy to Clipboard Toggle word wrap

3. 从 OLM Operator 中删除 OperatorLifecycleManagerV2=true 功能门。

   1. 编辑 OLM Operator 的 Deployment 对象：

      $ oc -n openshift-operator-lifecycle-manager \
          edit deployment olm-operator

      Copy to Clipboard Toggle word wrap

   2. 从 Deployment 对象的 args 部分中删除以下标记：

      ...
          spec:
            containers:
            - args:
      ...
              - --feature-gates 

      1

      
              - OperatorLifecycleManagerV2=true 

      2

      Copy to Clipboard Toggle word wrap

      1 2

      删除这些标记。

   3. 保存您的更改。

4. 重新启用 OLM 的 CVO 管理：

   $ oc patch clusterversion version \
       --type=merge -p \
       '{
          "spec":{
             "overrides":[
                {
                   "kind":"Deployment",
                   "name":"olm-operator",
                   "namespace":"openshift-operator-lifecycle-manager",
                   "unmanaged":false,
                   "group":"apps/v1"
                }
             ]
          }
       }'

5. 验证 Operator 资源已不再可用：

   $ oc get operators

   Copy to Clipboard Toggle word wrap

   输出示例

   error: the server doesn't have a resource type "operators"
