4.2. 使用节点选择器和容限创建项目

流程

1. 输入以下命令来编辑部署 Red Hat Quay 的命名空间，以及以下注解：

   $ oc annotate namespace <namespace> openshift.io/node-selector='node-role.kubernetes.io/infra='

   输出示例

   namespace/<namespace> annotated

2. 输入以下命令来获取可用 pod 列表：

   $ oc get pods -o wide

   输出示例

   NAME                                               READY   STATUS      RESTARTS        AGE     IP            NODE                                         NOMINATED NODE   READINESS GATES

3. 输入以下命令删除可用的 pod:

   $ oc delete pods --selector quay-operator/quayregistry=example-registry -n quay-enterprise

   输出示例

   pod "example-registry-clair-app-5744dd64c9-9d5jt" deleted
   pod "example-registry-clair-app-5744dd64c9-fg86n" deleted
   pod "example-registry-clair-postgres-845b47cd88-vdchz" deleted
   pod "example-registry-quay-app-64cbc5bcf-8zvgc" deleted
   pod "example-registry-quay-app-64cbc5bcf-pvlz6" deleted
   pod "example-registry-quay-app-upgrade-8gspn" deleted
   pod "example-registry-quay-database-784d78b6f8-2vkml" deleted
   pod "example-registry-quay-mirror-d5874d8dc-fmknp" deleted
   pod "example-registry-quay-mirror-d5874d8dc-t4mff" deleted
   pod "example-registry-quay-redis-79848898cb-6qf5x" deleted

   删除 pod 后，它们会自动重新启动，并应调度到专用的基础架构节点。
