（编者按：在上一篇文章中，我们聊了关于TF组件安装中的HA行为、多NIC安装、集群规模等问题，以及如何安装具有Tungsten Fabric CNI的Kubernetes HA环境。）
OpenStack
Openstack HA的安装可以由anstack-deployer直接完成。
对于此示例的设置，我使用了5个EC2实例（AMI相同，ami-3185744e），每个实例具有2个vCPU、8 GB内存、20 GB磁盘空间。VPC的CIDR为172.31.0.0/16。

$ 注意：如果计算节点不支持kvm，则可能需要添加此设置。
vi /etc/kolla/nova-compute/nova.conf
(add them in [libvirt] section)
virt_type=qemu
cpu_mode=none
docker restart nova_compute注意：如果是使用AWS，则还需要从EC2实例的右键菜单中设置网络>管理IP地址，以允许从其它节点访问haproxy VIP。
这样，控制器之间的HA和2个计算节点之间的overlay都完全配置好了！
有些要点本文档没有覆盖，例如某些控制节点宕机时的行为，或在计算节点之间执行实时迁移。上次我尝试实时迁移时，发现有大约1秒钟的报文丢包，但是请注意自己的设置，因为有很多要注意的地方（例如前缀将在实时迁移完成后更新）。
查看每个控制器的邻居状态和路由表，您会发现它们之间的有趣之处。

[root@ip-172-31-6-90 ~]# 由于vRouter始终具有2个XMPP连接，所以当存在3个控制器时，XMPP的连接状态在控制器之间是不同的，并且它们之间的路由表也可能有所不同。考虑到路由目标过滤，如果某些控制器未从XMPP接收到某些特定的路由目标，则它们甚至可能具有完全不同的路由表。
这就是由于Tungsten Fabric的横向扩展行为带来的结果。
有关ansible-ployer的更详细的配置（包括多NIC示例），您可以看看这些文档。

vCenter
Tungsten Fabric可以很好地与vCenter集成在一起，我们在“编排器集成”的部分有所描述。
要尝试此功能，可以按照以下说明进行操作。
- https://github.com/Juniper/contrail-ansible-deployer/blob/master/README_vcenter.m
- 请注意vRouterVM的OVF文件目前还未公开提供
由于Tungsten Fabric的HA行为与Kubernetes和OpenStack安装中的行为完全相同，因此我将不对其进行详细描述。
对于编排器端的HA，vCenter HA是完全可用的。
- 我尚未尝试过这种组合，但是由于vCenter HA将使用与vCenter服务相同的IP，因此我认为vcenter-plugin与vCenter HA一起使用的可能性很高。
多vCenter或跨vCenter（使用链接模式时）将是一个很有趣的主题。我将在附录部分进一步讨论它们。
容器标签的使用
容器注册表docker.io/opencontrailnight具有各种各样的标签。
关于在新的安装中选择什么样的标签，我有一些考虑。
我经常使用的是三个标签：latest，5.1.0-latest，5.0-latest。它们位于每个Tungsten Fabric分支的头部（master/R5.1/R5.0），并且每个分支中都包含各种错误修复。因此，您可以为用例选择其中的标签。如果需要R5.1中的新功能（例如可选的analytics组件），那么你可以选择5.1.0-latest标签。
由于latest是真正的开发分支，因此我不建议您将它们作为常规使用的标签，因为在某些情况下，此版本已被“破坏”以添加新的功能。
其它发行版本的分支更加稳定，因为在大多数情况下，它们只是进行了错误修复，尽管在创建新的分支后的某些特定时期内，发行版本的分支似乎也具有新的功能。
要指定标签，您可以使用这些参数，并且当针对ansible-deployer和conutil-container-builder输入git clone时，还需要指定同一分支。
(ansible-deployer)
git clone -b R5.1 http://github.com/Juniper/contrail-ansible-deployer
contrail_configuration:
CONTRAIL_CONTAINER_TAG: 5.1.0-latest
(kubeadm)
git clone -b R5.1 https://github.com/Juniper/contrail-container-builder.git
common.env in contrail-container-builder repo
CONTRAIL_CONTAINER_TAG: 5.1.0-latest需要注意的一点是，由于与OpenStack一起使用的容器（例如nova-init、neutron-init、heat-init等）具有OpenStack发行版的版本依赖性，因此标记可能需要更改为5.1.0-latest-queens、5.1.0-latest-rocky等。
由于安装了一些带有特定版本的OpenStack模块，因此，如果标签不同，则OpenStack容器将无法正常工作。
