[1] Network ノードで Magnum サービス をインストールします。インストール中の問いには全て [No] で OK です。
root@network:~#
apt -y install magnum-api magnum-conductor python3-magnumclient nginx libnginx-mod-stream
[2] Magnum の設定です。
root@network:~#
mv /etc/magnum/magnum.conf /etc/magnum/magnum.conf.org

root@network:~#
vi /etc/magnum/magnum.conf
# 新規作成

[cinder]
default_docker_volume_type = lvm-magnum

[cinder_client]
region_name = RegionOne

[magnum_client]
region_name = RegionOne

root@network:~#
chgrp magnum /etc/magnum/magnum.conf

root@network:~#
mkdir /var/lib/magnum/{tmp,certificates}

root@network:~#
chown magnum:magnum /var/lib/magnum/{tmp,certificates}

root@network:~#
sed -i -e "s/UWSGI_BIND_IP=\"\"/UWSGI_BIND_IP=\"127.0.0.1\"/" /etc/init.d/magnum-api

[3] ネットワークノード用の SSL/TLS 証明書を取得 または 自己署名の証明書を作成して、Nginx にプロキシの設定をします。
root@network:~#
unlink /etc/nginx/sites-enabled/default

root@network:~#
vi /etc/nginx/nginx.conf
# 最終行に追記

stream {
    upstream magnum-api {
        server 127.0.0.1:9511;
    }
    server {
        listen 10.0.0.50:9511 ssl;
        proxy_pass magnum-api;
    }
    ssl_certificate "/etc/letsencrypt/live/network.srv.world/fullchain.pem";
    ssl_certificate_key "/etc/letsencrypt/live/network.srv.world/privkey.pem";
}
[4] データベースにデータを追加して Magnum サービスを起動します。
root@network:~#
su -s /bin/bash magnum -c "magnum-db-manage upgrade"

root@network:~#
systemctl restart magnum-api magnum-conductor

root@network:~#
systemctl enable magnum-api magnum-conductor

root@network:~#
systemctl restart nginx

[5] Control ノードでステータスを確認します。[up] 状態であれば OK です。
また、[magnum.conf] で設定した Magnum 用の Cinder ボリュームタイプを作成しておきます。
