3.6.2.2. 環境変数の設定
次の環境変数をエクスポートします。
export OPERATOR_NAMESPACE=<namespace where the 3scale operator is running>
export THREESCALE_NAMESPACE=<namespace where the 3scale instance is running>さらに、レプリカ数に次の変数を割り当てます。これは、3scale インスタンスを再びスケールアップする際に、スケールダウンした時と同じレプリカ数に確実に復元するために行われます。
APICAST_PRODUCTION_REPLICA_COUNT=$(oc get deployment -n $THREESCALE_NAMESPACE apicast-production -o=jsonpath='{.spec.replicas}')

ZYNC_QUE_REPLICA_COUNT=$(oc get deployment zync-que -n $THREESCALE_NAMESPACE -o=jsonpath='{.spec.replicas}')必要に応じて、レプリカ数をバックアップとしてファイルに書き込む場合は、次のコマンドを実行します。
set | grep REPLICA_COUNT > replica_counts.txt
先ほど作成したすべての変数とその値が replica_counts.txt ファイルに記載されます。
