自服务网络¶

自服务（项目）网络仅包含虚拟组件，因此使项目能够在无需额外配置底层物理网络的情况下管理它们。OVN 机制驱动程序支持 Geneve 和 VLAN 网络类型，优先使用 Geneve。项目可以选择隔离自服务网络，通过路由器连接两个或多个网络，或通过具有适当功能的路由器将它们连接到提供商网络。与提供商网络类似，自服务网络可以使用任意名称。

注意

与提供商网络类似，自服务 VLAN 网络映射到每个计算节点上的唯一桥接，该桥接支持启动这些网络上的实例。自服务 VLAN 网络还需要在主机和 OVS 级别执行几个命令。以下示例假定使用 Geneve 自服务网络。

创建自服务网络¶

创建自服务网络涉及在网络服务级别执行几个命令，从而在 OVN 级别产生一系列操作以创建虚拟网络组件。以下示例创建一个 Geneve 自服务网络并将其绑定到一个子网。该子网使用 DHCP 分配 IP 地址给实例。

在控制器节点上，获取常规（非特权）项目的凭据。以下示例使用 demo 项目。

在控制器节点上，在网络服务中创建一个自服务网络。

OVN 机制驱动程序和 OVN 在创建自服务网络期间执行以下操作。

机制驱动程序将网络转换为 OVN 北向数据库中的逻辑交换机。

注意

这些操作不会在任何节点上创建流。

在自服务网络上创建子网¶

自服务网络至少需要一个子网。在大多数情况下，环境为实例的 IP 地址分配、默认网关 IP 地址以及名称解析等元数据提供合适的值。

在控制器节点上，创建一个绑定到自服务网络 selfservice 的子网。

OVN 操作¶

OVN 机制驱动程序和 OVN 在自服务网络上创建子网期间执行以下操作。

如果子网使用 DHCP 进行 IP 地址管理，则为服务于该子网的每个 DHCP 代理创建逻辑端口，并将它们绑定到逻辑交换机。在此示例中，该子网包含两个 DHCP 代理。
