OpenStack Caracal : ネットワークを構成する2024/08/06 |
|
仮想マシンインスタンスが利用するネットワークを構成します。 All in One 構成の Neutron サービス または ノード毎に分離設定した Neutron サービスを事前に構成済みであることが前提です。
当例では、以下のような All in One 構成の環境を前提に、シンプルな FLAT タイプのネットワークを構成します。
eth0|10.0.0.30
+-----------+-----------+
| [ dlp.srv.world ] |
| (Control Node) |
| |
| MariaDB RabbitMQ |
| Memcached Nginx |
| Keystone httpd |
| Glance Nova API |
| Nova Compute |
| Neutron Server |
| Open vSwitch |
| OVN Metadata Agent |
| OVN-Controller |
+-----------+-----------+
eth1|(UP with no IP)

| [1] | Neutron サービスに追加設定します。 |

# ブリッジ追加 [root@dlp ~(keystone)]# ovs-vsctl add-br br-eth1
# 追加したブリッジのポートに [eth1] を追加 # [eth1] は環境によって異なるため自身の環境に置き換え [root@dlp ~(keystone)]# ovs-vsctl add-port br-eth1 eth1
# ブリッジと [physnet1] をマッピング : [physnet1] の名称は任意 [root@dlp ~(keystone)]# ovs-vsctl set open . external-ids:ovn-bridge-mappings=physnet1:br-eth1
