5.4. 将网络服务用于 RHOSO 数据平面

将现有 Red Hat OpenStack Platform 中的 Networker 服务部署到 OpenShift (RHOSO)数据平面上的 Red Hat OpenStack Services 中。Networker 服务可以在 Controller 节点或专用 Networker 节点上运行。您决定要在 Networker 节点上运行哪些服务，并为 Networker 节点创建单独的 OpenStackDataPlaneNodeSet 自定义资源(CR)。如果选项适用于您的环境，您可能还决定实现以下选项：

根据您的拓扑，您可能需要在节点上运行 neutron-metadata 服务，特别是为 Compute 节点上托管的 SR-IOV 端口提供元数据时。
如果要在 Networker 节点上运行 OVN 网关服务，请在要部署的列表中保留 ovn 服务。
可选：您可以在 Networker 节点上运行 neutron-dhcp 服务，而不是在 Compute 节点上运行。除非部署使用 DHCP 转发或 dnsmasq 支持的高级 DHCP 选项，否则您可能不需要将 neutron-dhcp 与 OVN DHCP 实施一起使用。

当节点设置为 OVN chassis 网关时，将现有 Red Hat OpenStack Platform 部署中的每个 Controller 或 Networker 节点采用到 OpenShift 上的 Red Hat OpenStack Services (RHOSO)。任何参数设置为 enable-chassis-as-gw 的节点都被视为 OVN 网关机箱。在这种情况下，此类节点将在使用后成为 edpm 网络器节点。

检查运行 OVN Controller 网关代理 的节点。代理列表因您启用的服务而异：

oc exec openstackclient -- openstack network agent list

先决条件

定义 shell 变量。根据上面的代理列表输出，controller-0、controller-1、controller-2 是我们的目标主机。如果您有 Controller 和 Networker 节点都运行 networker 服务，那么请在下面添加所有这些主机。
```
declare -A networkers
networkers+=(
  ["controller-0.localdomain"]="192.168.122.100"
  ["controller-1.localdomain"]="192.168.122.101"
  ["controller-2.localdomain"]="192.168.122.102"
  # ...
)
```
```
declare -A networkers
networkers+=(
  ["controller-0.localdomain"]="192.168.122.100"
  ["controller-1.localdomain"]="192.168.122.101"
  ["controller-2.localdomain"]="192.168.122.102"
  # ...
)
```

- 根据您的环境，将 ["<node-name>"]="192.168.122.100" 替换为相应 Networker 或 Controller 节点的名称和 IP 地址。

流程

为您的节点部署 OpenStackDataPlaneNodeSet CR：

注意

您可以重复使用为 Compute 节点指定的 OpenStackDataPlaneNodeSet CR 中的大多数 nodeTemplate 部分。您可以省略一些变量，因为 Networker 节点上运行的一组有限服务。

验证完成后，确认 Ansible EE pod 的状态为 Completed ：

等待部署变为 Ready 状态：

为 Networker 节点部署 OpenStackDataPlaneDeployment CR：

oc apply -f - <<EOF
apiVersion: dataplane.openstack.org/v1beta1
kind: OpenStackDataPlaneDeployment
metadata:
  name: openstack-networker
spec:
  nodeSets:
  - openstack-networker
EOF

$ oc apply -f - <<EOF
apiVersion: dataplane.openstack.org/v1beta1
kind: OpenStackDataPlaneDeployment
metadata:
  name: openstack-networker
spec:
  nodeSets:

注意

另外，在部署主 OpenStackDataPlaneDeployment CR 前，您可以在 nodeSets 列表中包含 Networker 节点。您不能在部署后将新节点设置为 OpenStackDataPlaneDeployment CR。

清理不再运行的任何网络服务(neutron)代理。

注意

在某些情况下，来自被替换或停用的旧数据平面的代理保留在 RHOSO 中。提供的这些代理可能由 RHOSO 中运行的新代理提供，或者功能可能被其他组件替代。例如，可能不再需要 DHCP 代理，因为 RHOSO 中的 OVN DHCP 可以提供此功能。

列出代理：

oc exec openstackclient -- openstack network agent list

$ oc exec openstackclient -- openstack network agent list

如果列表中的任何代理在 Alive 字段中显示 XXX，请验证 Host 和 Agent Type，如果不再需要此代理，且代理已在 Red Hat OpenStack Platform 主机上永久停止。然后，删除代理：
```
oc exec openstackclient -- openstack network agent <agent_id>
```
```
$ oc exec openstackclient -- openstack network agent <agent_id>
```

- 将 <agent_id > 替换为要删除的代理 ID，例如 856960f0-5530-46c7-a331-6eadcba362da。

验证

确认所有 Ansible EE pod 都到达 Completed 状态：

watch oc get pod -l app=openstackansibleee

$ watch oc get pod -l app=openstackansibleee

等待 data plane 节点设置为 Ready 状态：
```
oc wait --for condition=Ready osdpns/<networker_CR_name> --timeout=30m
```
```
$ oc wait --for condition=Ready osdpns/<networker_CR_name> --timeout=30m
```
Copy to Clipboard Toggle word wrap
- 将 <networker_CR_name > 替换为您为 Networker 节点部署的 CR 名称，如 openstack-networker。

验证 Networking 服务(neutron)代理是否正在运行。代理列表因您启用的服务而异：

oc exec openstackclient -- openstack network agent list

$ oc exec openstackclient -- openstack network agent list
