第9章 デプロイメントプロセスの監視およびデバッグ

手順

1. 次のコマンドを入力して、デプロイメントのステータスを確認します。

   $ oc get quayregistry -n quay-enterprise -o yaml

   出力例

   デプロイメント直後に、QuayRegistry オブジェクトに基本設定が表示されます。

   apiVersion: v1
   items:
   - apiVersion: quay.redhat.com/v1
     kind: QuayRegistry
     metadata:
       creationTimestamp: "2021-09-14T10:51:22Z"
       generation: 3
       name: example-registry
       namespace: quay-enterprise
       resourceVersion: "50147"
       selfLink: /apis/quay.redhat.com/v1/namespaces/quay-enterprise/quayregistries/example-registry

   kind: List
   metadata:
     resourceVersion: ""
     selfLink: ""

2. oc get pods コマンドを使用して、デプロイされたコンポーネントの現在の状態を表示します。

   $ oc get pods -n quay-enterprise

   出力例

3. デプロイメントが進行中、QuayRegistry オブジェクトに現在のステータスが表示されます。この場合、データベースの移行が行われ、その他のコンポーネントは完了するまで待機します。

     status:
       conditions:
       - lastTransitionTime: "2021-09-14T10:52:04Z"

           type: Available

4. デプロイメントプロセスが正常に終了すると、QuayRegistry オブジェクトのステータスには正常でないコンポーネントは表示されません。

     status:
       conditions:
       - lastTransitionTime: "2021-09-14T10:52:36Z"
         lastUpdateTime: "2021-09-14T10:52:36Z"

         message: all objects created/updated successfully
         reason: ComponentsCreationSuccess
         status: "False"
