千家信息网最后更新 2026年11月03日Tungsten Fabric入门宝典丨多编排器用法及配置

在多个编排器之间共享控制平面有很多好处，包括routing/bridging、DNS、security等。

下面我来描述每种情况的使用方法和配置。

K8s+OpenStack

Kubernetes + OpenStack的组合已经涵盖并且运行良好。

https://github.com/Juniper/contrail-ansible-deployer/wiki/Deployment-Example:-Contrail-and-Kubernetes-and-Openstack

另外，Tungsten Fabric支持嵌套安装（nested installation）和非嵌套安装（non-nested installation），因此你可以选择其中一个选项。

https://github.com/Juniper/contrail-kubernetes-docs

K8s+K8s

将多个Kubernetes集群添加到一个Tungsten Fabric中，是一种可能的安装选项。

由于kube-manager支持cluster_name参数，该参数修改了将要创建的租户名称（默认为"k8s"），因此这应该是可行的。不过，我在上次尝试该方法时效果不佳，因为有些对象被其它kube-manager作为陈旧对象（stale object）删除了。

https://github.com/Juniper/contrail-container-builder/blob/master/containers/kubernetes/kube-manager/entrypoint.sh#L28

在将来的版本中，可能会更改此行为。

注意：

从R2002及更高版本开始，这个修补程序解决了该问题，并且不再需要自定义修补程序。

注意：应用这些补丁，似乎可以将多个kube-master添加到一个Tungsten Fabric集群中。

由于kube-master创建的pod-network都在同一个Tungsten Fabric controller上，因此在它们之间实现路由泄漏（route-leak）是可能的:)

由于cluster_name将成为Tungsten Fabric的fw-policy中的标签之一，因此在多个Kubernetes集群之间也可以使用相同的标签

OpenStack+OpenStack

我还没有尝试将两个OpenStack集群添加到一个Tungsten Fabric controller中，但如果它们不使用相同的租户名称，那么应该是可行的。

K8s+vCenter

Kubernetes和vCenter的组合可以同时使用。用例类似于Kubernetes + OpenStack。

OpenStack+vCenter

OpenStack和vCenter的组合有点奇怪，因为OpenStack仪表盘可能用作vCenter网络的管理UI。

根据我的尝试，vcenter-plugin会检查所有可用租户下的所有virtual-network，而不是"vCenter"租户下的virtual-network，因此，如果创建了virtual-network或其它Neutron组件，也可以在ESXi上的vRouterVM上使用。通过此设置，vCenter用户可以自己实现网络功能，就像使用EC2 / VPC一样。
