概要

これまでの記事では、nebula-f1をフロントエンド（管理ノード）専用として構成してきました。この記事では、OneDeployの設定を更新し、nebula-f1をコンピュートノードとしても機能させるための準備を行います。

前提条件

OpenNebula 7.0がOneDeployでデプロイ済み
OneDeploy実行環境（Ansibleコントロールノード）にアクセス可能
example.yamlファイルが保存されている
nebula-f1, nebula-n1, nebula-n2が稼働中

環境情報

ホスト名	IPアドレス	現在の役割	変更後の役割
nebula-f1	192.168.11.110	Frontend	Frontend + Compute
nebula-n1	192.168.11.111	Compute	Compute
nebula-n2	192.168.11.112	Compute	Compute

作業手順

1. OneDeploy実行環境へのアクセス

# OneDeploy実行環境（Ansibleコントロールノード）にログイン

cd ~/one-deploy/my-one

# example.yamlの存在確認
ls -l example.yaml

2. 現在のexample.yamlの確認

cat example.yaml

現在の設定例:

flathill@nebula-f1:~/one-deploy/my-one$ cat example.yml
---
all:
  vars:
    ansible_user: flathill
    ansible_become: true
    ansible_become_method: sudo
    one_version: '7.0'
    one_pass: opennebulapass
    ensure_hosts: true
    ensure_keys: true
    features:
      evpn: false
      evpn_greedy: false
    ds:

        managed: true
        template:
          VN_MAD: bridge

          NETWORK_ADDRESS: 192.168.11.0
          NETWORK_MASK: 255.255.255.0
          GATEWAY: 192.168.11.1
          DNS: 1.1.1.1

frontend:
  hosts:

    nebula-n1: { ansible_host: 192.168.11.111 }
    nebula-n2: { ansible_host: 192.168.11.112 }

3. example.yamlのバックアップ

# 元の設定をバックアップ
cp -p example.yml example.yml.backup.$(date +%Y%m%d_%H%M%S)

# バックアップの確認
ls -l example.yaml*

4. example.yamlの編集

vi example.yaml

修正後の内容:

    nebula-n2: { ansible_host: 192.168.11.112 }

変更点: nodes セクションに nebula-f1 (192.168.11.110) を追加しました。

保存して終了（Ctrl+O, Enter, Ctrl+X）

5. 設定変更の確認

# 差分の確認
diff -ruN example.yaml.backup.* example.yaml

6. Ansible接続テスト

# nebula-f1への接続確認
ansible -i example.yml f1 -m ping

7. OneDeployの再適用（nebula-f1のみ）

# nebula-f1のみにKVMノード設定を適用
ansible-playbook -i example.yml opennebula.deploy.main --limit nebula-f1

10. Sunstone WebUIでの確認

Sunstone WebUI (http://192.168.11.110:9869) にアクセス
Infrastructure > Hosts を開く
nebula-f1 が表示され、状態が on であることを確認

まとめ

この記事では、OneDeployの設定を更新し、nebula-f1をコンピュートノードとしても機能させるための設定を完了しました。

完了した作業:

example.yamlに nebula-f1 を nodes として追加
Ansible Playbookを再適用し、KVM関連パッケージとlibvirtdを設定
OpenNebulaホストとして nebula-f1 (f1) を登録
