IBM Cloud pak for Watson AIOps. 4.1.0をデプロイする

Last updated at Posted at 2023-07-03

下記のドキュメントを参考にIBM Cloud Pak for Watson AIOpsの構築を行う。
現在の最新バージョンは4.1.0
3.7.xのインストールはこちらを参照。

前回の3.7のデプロイ記事と大まかな流れは変わらないです。
しかしながらyamlファイルの指定バージョンを4.1に変える所以外にも変更がすこしあるので注意してください。

なお、前回のデプロイ記事同様、検証環境をデプロイすることを前提とした記事なのであしからず。

↓　参考とするドキュメント　↓

前提条件(前回と同じままなので要編集)

  • Watson AIOpsをインストールするOpenshift Container Platformがインストールできている

  • 最低限Worker合計でリソースの余裕がある

    • vCPU:56
    • Memory:140GB
    • CoreoOS root disk 360GB

  • Worker個々で以下のリソースがある(最低3worker必要)

    • vCPU:8
    • memory:12GB
    • Local disk Storage 120

  • その他スループットなど細かいrequirementは下記を参照

インストール作業

namespace 作成

oc create namespace cp4waiops

Operator Group作成

cat << EOF | oc apply -f -
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: cp4waiops-operator-group
  namespace: cp4waiops
spec:
  targetNamespaces:
    - cp4waiops
EOF

pullsecretを作成

コンテナイメージを引っ張ってくるためのパスワードとしてENTITLEMENT_KEYが必要。
$YOUR_ENTITLEMENT_KEYは
https://myibm.ibm.com/products-services/containerlibrary
より取得してください。

oc create secret docker-registry ibm-entitlement-key \
    --docker-username=cp\
    --docker-password=$YOUR_ENTITLEMENT_KEY \
    --docker-server=cp.icr.io \
    --namespace=cp4waiops

AI Managerの外向け通信を許可

if [ $(oc get ingresscontroller default -n openshift-ingress-operator -o jsonpath='{.status.endpointPublishingStrategy.type}') = "HostNetwork" ]; then oc patch namespace default --type=json -p '[{"op":"add","path":"/metadata/labels","value":{"network.openshift.io/policy-group":"ingress"}}]'; fi

カタログソース作成

cat << EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: ibm-operator-catalog
  namespace: openshift-marketplace
spec:
  displayName: ibm-operator-catalog
  publisher: IBM Content
  sourceType: grpc
  image: icr.io/cpopen/ibm-operator-catalog:latest
  updateStrategy:
    registryPoll:
      interval: 45m
EOF

前提条件のチェック

ツールでインストールの前提条件が満たされているか確認を行う
チェック内容はOCPのバージョン、CPU、メモリなどのリソース状況やStorage classが所望のものができているかなどをチェックしてくれる。

git clone https://github.com/IBM/cp4waiops-samples
cd cp4waiops-samples/prereq-checker/4.1
oc project cp4waiops
./prereq.sh

出力結果(長いので注意)

AI Ops Operatorのインストールを行う

Operatorのインストール確認

下記コマンドでOperatorのインストールが上手くいっているかどうかが分かる.大体数分でインストールは終了します

oc get csv -n cp4waiops | egrep "ibm-aiops-orchestrator|ibm-automation|ibm-common-service"

出力例

ドキュメントに記載があるのですが、この段階ではIBM Elasticのインストールがfailします。ですが、気にせずAI Managerのインストールに進んでください。AI ManagerをインストールするとIBM ElasticのインストールもSucceededになります。

[root@itz-664002upfl-0kba ~]# oc get csv -n cp4waiops | egrep "ibm-aiops-orchestrator|ibm-automation|ibm-common-service"

ibm-aiops-orchestrator.v4.1.0         IBM Cloud Pak for Watson AIOps AI Manager          4.1.0                                        Succeeded

AI Managerをインストールする

変数である'storage_class_name'と
'large_block_storage_class_name'
は下記ドキュメントの'Table 2. Supported storage providers'
を参照。Storage providerにより値が変わります.

cat << EOF | oc apply -f -
apiVersion: orchestrator.aiops.ibm.com/v1alpha1
kind: Installation
metadata:
  name: ibm-cp-watson-aiops
  namespace: cp4waiops
spec:
  imagePullSecret: ibm-entitlement-key
  license:
    accept: true
  pakModules:
  - name: aiopsFoundation
    enabled: true
  - name: applicationManager
    enabled: true
  - name: aiManager
    enabled: true
  - name: connection
    enabled: false
  size: small
  storageClass: <storage_class_name>
  storageClassLargeBlock: <large_block_storage_class_name>
  topologyModel: application
EOF

私の環境ではODFを使っており、下記のように書き換えを行いました。
ODFの場合

storage_class_name =　ocs-storagecluster-cephfs

large_block_storage_class_name = ocs-storagecluster-ceph-rbd

なので、下記のように書き換えます。

cat << EOF | oc apply -f -
apiVersion: orchestrator.aiops.ibm.com/v1alpha1
kind: Installation
metadata:
  name: ibm-cp-watson-aiops
  namespace: cp4waiops
spec:
  imagePullSecret: ibm-entitlement-key
  license:
    accept: true
  pakModules:
  - name: aiopsFoundation
    enabled: true
  - name: applicationManager
    enabled: true
  - name: aiManager
    enabled: true
  - name: connection
    enabled: false
  size: small
  storageClass: ocs-storagecluster-cephfs
  storageClassLargeBlock: ocs-storagecluster-ceph-rbd
  topologyModel: application
EOF

インストールには60-90分かかるらしいのでしばらく待ちます。

AI Manager のインストール確認

しばらく寝かせておいたあとにインストールの確認コマンドを打ちます

oc get installations.orchestrator.aiops.ibm.com -n cp4waiops
