ROKSへのDb2 Warehouse(SMP)デプロイログとOLTP版との手順相違点

概要

• IBM Cloud上のマネージドOpenShift環境である ROKS に Db2 Warehouseをデプロイします
• OpenShift/Kubernetes環境でDb2を動かすには、マイクロサービスとして開発された専用のDb2を導入する必要があります
  • Db2 Warehouse on Red Hat OpenShift and Kubernetes、別名Db2Uとも呼ばれます
  • Db2として公式の Kubernetes Operator が提供されます
    • 同じ Operator db2oltp(OLTP用途)とdb2wh(Warehouse:分析用)どちらかを選択してデプロイします
  • Operator導入後は、Yamlを書けばDb2を構築できます
• db2whは、db2oltpとほぼ同じ手順で構築できますが、ストレージ構成やDb2レジストリ変数などは一部変更する必要がありました

環境 / 構成

• OpenShift Container Platform 4.14.24
• Db2 Operator 110509.0.1
• Db2 for OpenShift and Kubernetes (Db2U) s11.5.9.0-cn1
  • 1node, partitionConfig total=1
• Persistent Volume Claim(PVC)構成 :

ストレージクラスは、今回の環境にて利用可能なものでDb2がサポートするクラスを指定します。

上の図はマニュアルから引用しています。
グレーの網掛けを重ねている部分は今回構成しなかったコンポーネントです。

PVC	PVC作成の必要性	アクセスモード	ストレージクラス
SHARED META	必須	RWX	ocs-storagecluster-cephfs
DATA	必須	RWO	ocs-storagecluster-ceph-rbd
アクティブログ	オプション(*1)	RWO	ocs-storagecluster-ceph-rbd
アーカイブログ	オプション(*1)	RWX	ocs-storagecluster-cephfs
一時表スペース	オプション(*2)	RWO	ocs-storagecluster-ceph-rbd
バックアップ	オプション(*2)	RWX	ocs-storagecluster-cephfs

　(*1) 専用PVCを作らない場合、DATAのPVCに保持される
　(*2) 専用PVCを作らない場合、SHARED METAのPVCに保持される

導入手順(概要)

Db2 Warehouseは元々Docker版として提供されましたが、OpenShift / Kubernetes 環境でDb2 Warehouseを利用するには、マイクロサービスとして実装される Db2 for Red Hat OpenShift and Kubernetes(Db2U) を利用します。

以下の流れでデプロイを進めます。

Step1. OpenShift プロジェクト作成
Step2. Db2 Operator導入
Step3. Security Context Constraint 設定
Step4. Db2 Warehouseエンジン導入

Step1-3までの手順は、通常のOLTP用Db2を利用する場合もDb2 Warehouseを利用する場合も共通です。

導入手順 (ログ)

IBM ROKS環境へ Db2U を導入した際の手順、スクリーンショットを記録として残します。

Step1. プロジェクト作成

Db2デプロイ用のネームスペースを作成します。

root@myhost:~# oc new-project db2-1
Now using project "db2-1" on server "https://c115-e.jp-tok.containers.cloud.ibm.com:30769".

You can add applications to this project with the 'new-app' command. For example, try:

    oc new-app rails-postgresql-example

to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:

    kubectl create deployment hello-node --image=k8s.gcr.io/serve_hostname

root@myhost:~#

Step2. Db2 Operator導入

Step2-1. IBM Operator Catalog 導入

IBM Operator CatalogをOCP環境に導入します。
Db2マニュアルに提供されるYaml定義を利用して、IBM Operator Catalog の CatalogSourceリソースを作成します。

(IBM Operator Catalog)

apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: ibm-operator-catalog
  namespace: openshift-marketplace
spec:
  displayName: "IBM Operator Catalog" 
  publisher: IBM
  sourceType: grpc
  image: icr.io/cpopen/ibm-operator-catalog
  updateStrategy:
    registryPoll:
      interval: 45m

OpenShift Webコンソール上で「＋」を押下します

YAMLのインポート画面が開くので、エディタ部分に上記Yaml定義を貼付して「作成」を押下します

即時に作成完了し、カタログソースの詳細画面に遷移します

コマンドラインからも、CatalogSource およびパッケージマニフェストが正常に作成されていることを確認します

root@myhost:~# oc get CatalogSource -n openshift-marketplace
NAME                   DISPLAY                TYPE   PUBLISHER   AGE
certified-operators    Certified Operators    grpc   Red Hat     30d
community-operators    Community Operators    grpc   Red Hat     30d
ibm-operator-catalog   IBM Operator Catalog   grpc   IBM         17d
redhat-marketplace     Red Hat Marketplace    grpc   Red Hat     30d
redhat-operators       Red Hat Operators      grpc   Red Hat     30d

"ibm-operator-catalog" が作成されていることが確認されます

Step2-2. Db2 Operator 導入

OpenShift Webコンソールを開き、メニューバーの [Operator] -> [OperatorHub] を選択します。
画面上部のテキストボックスに「Db2」と入力すると、Db2関連のオペレータに表示が絞られます。

「IBM Db2」を選択すると、Db2U Operator Readmeが表示されます。(画面右半分)
Db2U Opearator 導入後～Db2エンジンのDeployまでに実行する必要のある作業や前提条件が記載されていますので必ず目を通します。
※ Operatorインストール後も同じReadmeを参照可能です

Operator Readme 画面左上の「インストール」を押下し、Db2U Operator を導入します。
インストールモード、インストール対象となるNamespaceなど必要な項目を選択し、「インストール」を押下するとDb2U Operatorの導入が始まります。

「更新の承認」を「手動」にしている場合は、承認が要求されます

数分もかからず完了します

「Operatorの表示」を押下すると、Db2U Operator の詳細画面に遷移します

これでDb2U Operatorのセットアップが完了しました。

Step3. セキュリティ構成

Step3-1. Secret 構成

後のDb2U Cluster(Db2インスタンス本体)の導入時に必要となる Entitlement key を取得し、この key を含む Secret を作成しておきます。
Db2U Cluster導入時には、この Entitlement key を保持する Secret の名前を指定します。

①Entitlement key の取得

MyIBM のサイトにアクセスし、ライセンスが付与されているソフトウェアに関連付けられた IBMid とパスワードを入力しログインします。
https://myibm.ibm.com/products-services/containerlibrary

「Container software library」ページに表示されるライセンスを確認します。
この例では「IBM SOFTWARE ACCESS 1 YEAR : all」と表示されています。(※この画面の表示は一例です)

続いて「Entitlement keys」に移動してキーを取得します

[Copy key]ボタンを押下し、Entitlement key をコピーします(→後ほど利用するため、テキストファイル等に一時保管しておく)

②Image Pull Secret の作成

①で取得したENTITLEDKEY、 EMAILアドレス、プロジェクト(ネームスペース)名を環境に応じて設定し、oc create secret コマンドを実行します。

OS環境変数の設定：

root@myhost:~# ENTITLEDKEY="①で取得したEntitlement key"
root@myhost:~# EMAIL="[e-mail]"
root@myhost:~# NAMESPACE="db2u-1"

Secret作成：

root@myhost:~# oc create secret docker-registry ibm-registry   \
      --docker-server=cp.icr.io                   \
      --docker-username=cp                        \
      --docker-password=${ENTITLEDKEY}            \
      --docker-email=${EMAIL}                     \
      --namespace=${NAMESPACE}
secret/ibm-registry created

Secretが作成されました

root@myhost:~# oc get secret | grep ibm-registry
ibm-registry               kubernetes.io/dockerconfigjson        1      97s
root@myhost:~#

Step3-2. Security Context Constraints 構成

Db2マニュアル または Db2 Operator Readme に記載されるyaml定義をコピー＆ペーストし、SecurityContextConstraints定義を作成します。

※マニュアルとDb2U Operator Readmeに記載されるSecurity Context Constraintsのyaml文は同一です

db2u-sccが作成されていることを確認します

root@myhost:~/db2u# oc get scc | grep -i db2u-scc
db2u-scc                       true    ["SYS_RESOURCE","IPC_OWNER","SYS_NICE","CHOWN","DAC_OVERRIDE","FSETID","FOWNER","SETGID","SETUID","SETFCAP","SETPCAP","SYS_CHROOT","KILL","AUDIT_WRITE"]   MustRunAs   RunAsAny           RunAsAny    RunAsAny    10           false            ["awsElasticBlockStore","azureDisk","azureFile","cephFS","cinder","configMap","csi","downwardAPI","emptyDir","ephemeral","fc","flexVolume","flocker","gcePersistentDisk","gitRepo","glusterfs","iscsi","nfs","persistentVolumeClaim","photonPersistentDisk","portworxVolume","projected","quobyte","rbd","scaleIO","secret","storageOS","vsphere"]

Step4. Db2 WarehouseエンジンのDeploy

Db2/Db2 Warehouseは、バージョンやFixレベル、cnレベルでもyamlのフォーマットが変わるため、以下手順でデプロイするほうが確実です。

1. OCP Webコンソールでデプロイを行う(yamlの自動生成機能にできるだけ頼る)
2. フォームビューに表示される設定項目を設定
3. ストレージ構成(サイズ)など、フォームビューで編集できない項目をYamlビューで編集

Webコンソール左側のメニューバーより
「Operator」＞「インストール済みのOperator」＞「IBM Db2」を選択し、
表示された「Db2u Instance」パネル下の「インスタンスの作成」の文字をクリックします。

フォームビューとYamlビューを切り替えながら編集を行います。

変更箇所：

• 名前：db2uinstance-wh1
• Account > Image Pull Secrets
  • Step2-2で作成したsecret「ibm-registry」をドロップダウンリストから選択
• License > License
  • Acceptにチェック
• Environment
  • Database
    • Name : BLUDB1
      • 任意に指定可、デフォルトは「BLUDB」
    • Setting
      • Codeset : UTF-8
      • Collation：IDENTITY
      • Teritorry : US
    • dbConfig　　※Yamlビューで構成
      • LOGARCHMETH1 : "DISK:/mnt/logs/archive"
  • Instance
    • Password : (db2inst1ユーザのパスワードを任意に指定)
    • registry　※Yamlビューで構成
      DB2_4K_DEVICE_SUPPORT: "ON"
      DB2_ATS_ENABLE: 'NO'
      DB2_DISPATCHER_PEEKTIMEOUT: '2'
      DB2_OBJECT_STORAGE_SETTINGS: 'OFF'
• Storage ※Yamlビューで構成
  • meta / data / tmpts / activelog / archivelog / backup

編集後のyamlはこちらです。

Yamlの編集が終わったら、このままデプロイに進みます。

【補足】
再度同じ構成でデプロイを行う場合は、デプロイ前にYamlビューにて、Yaml全文をテキストファイルに保管しておくと便利です。

Step4-3. デプロイ(作成)

「作成」ボタンを押して、デプロイを開始します。

Step4-4. デプロイの進行状況確認

デプロイ中、Webコンソール上、ステータスは「NotReady」と表示されます。

デプロイ完了後は、ステータス「Ready」に変わります。

コマンドラインでは、より詳細な状況が把握できます。
oc get pod(または oc get allなど)にて確認し、以下の状態になっていればDeploy完了です。

Pod名	ステータス	備考
c-db2uinstance-wh1-db2u-0	Running	Db2エンジンのPod * db2syscが稼働
c-db2uinstance-wh1-restore-morph-z62x2	Completed	Db2セットアップの最後の処理(Restore)を行うJobに属するPod

oc get all(db2uinstance-wh1に絞った出力)

db2oltpとの違い

a. レジストリー変数 DB2_4K_DEVICE_SUPPORT: "ON" の必要性

db2whでは、DB2_4K_DEVICE_SUPPORT: "ON"を設定しないと Db2エンジンのPodが作成されませんでした。

同じ環境、同じストレージクラスを指定してデプロイした際、db2oltp s11.5.9.0-cn1 ではこのレジストリーの設定は不要でした。

b. Storageの定義箇所

マニュアル図を見る限り、Db2もDb2Warehouseも、Data/Activelogs/Tempts(赤線枠内)は Database(Db2 Engine) > Storage の配下に定義するように見えます。

Db2 Warehouseマニュアル引用：
https://www.ibm.com/docs/en/db2-warehouse?topic=db2-configuring-database-storage

db2oltpでは Database > Storage 配下に定義可能でしたが、db2whの場合は同じストレージ構成でYamlを記述すると、Data/Activelogs/Tempts のPVC/PVが作成されず、デプロイ失敗となりました。

補足

今回デプロイしたDb2 Warehouse環境の構成情報を取得。
