2.8. 移动默认 registry

流程

1. 查看 config/instance 对象：

   $ oc get configs.imageregistry.operator.openshift.io/cluster -o yaml

   Copy to Clipboard

   输出示例

   apiVersion: imageregistry.operator.openshift.io/v1
   kind: Config
   metadata:
     creationTimestamp: 2019-02-05T13:52:05Z
     finalizers:
     - imageregistry.operator.openshift.io/finalizer
     generation: 1
     name: cluster
     resourceVersion: "56174"
     selfLink: /apis/imageregistry.operator.openshift.io/v1/configs/cluster
     uid: 36fd3724-294d-11e9-a524-12ffeee2931b
   spec:
     httpSecret: d9a012ccd117b1e6616ceccb2c3bb66a5fed1b5e481623
     logging: 2
     managementState: Managed
     proxy: {}
     replicas: 1
     requests:
       read: {}
       write: {}
     storage:
       s3:
         bucket: image-registry-us-east-1-c92e88cad85b48ec8b312344dff03c82-392c
         region: us-east-1
   status:
   ...

   Copy to Clipboard

2. 编辑 config/instance 对象：

   $ oc edit configs.imageregistry.operator.openshift.io/cluster

   Copy to Clipboard

3. 修改对象的 spec 部分，使其类似以下 YAML：

   spec:
     affinity:
       podAntiAffinity:
         preferredDuringSchedulingIgnoredDuringExecution:
         - podAffinityTerm:
             namespaces:
             - openshift-image-registry
             topologyKey: kubernetes.io/hostname
           weight: 100
     logLevel: Normal
     managementState: Managed
     nodeSelector:
       node-role.kubernetes.io/infra: ""

   Copy to Clipboard

4. 验证 registry pod 已移至基础架构节点。

   1. 运行以下命令，以识别 registry pod 所在的节点：

      $ oc get pods -o wide -n openshift-image-registry

      Copy to Clipboard

   2. 确认节点具有您指定的标签：

      $ oc describe node <node_name>

      Copy to Clipboard

      查看命令输出，并确认 node-role.kubernetes.io/infra 列在 LABELS 列表中。
