Tungsten Fabric解决方案指南-Kubernetes集成

作者：Tony Liu 译者：TF编译组

1 Kubernetes与TF的集成

集成方案中，在Kubernetes和Tungsten Fabric（编者按：原文为Contrail，其开源版已更名为Tungsten Fabric，本文出现Contrail之处均以Tungsten Fabric替换）之间有两个连接。

contrail-kube-manager和kube-api-server
Contrail CNI

1.1 contrail-kube-manager

此服务连接到kube-api-server以接收更新。然后，它会连接到Tungsten Fabric配置API服务器，来创建必要的配置（VM，VMI /端口，IP等），以将容器连接到overlay层。它还会将更新发送到kube-api-server。

1.2 Contrail CNI

每个node/minion上的Kubelet都使用CNI参数运行。启动容器时，kubelet调用CNI来建立网络。Contrail CNI连接到vRouter代理REST API：

1）获得必要的配置
2）将容器网络接口插入vRouter

1.3 Gateway

Tungsten Fabric使用gateway连接overlay和underlay网络，以提供外部访问。我们需要使用gateway来支持Kubernetes的暴露服务和ingress功能。

必须在Tungsten Fabric中创建一个浮动IP池。

在/etc/contrailctl/kubemanager.conf中配置这个FIP池的FQ名称，以进行配置（provisioning）。

[KUBERNETES_VNC]public_fip_pool = {'domain': 'default-domain', 'project': 'default', 'network': 'public', 'name': 'public-fip-pool'}

在容器condir-kube-manager中，浮动IP池在/etc/contrail/contrail-kubernetes.conf中进行配置。

[VNC]public_fip_pool = {'domain': 'default-domain', 'project': 'default', 'network': 'public', 'name': 'public-fip-pool'}

在Kubernetes中公开service或创建ingress时，将从该池中分配一个FIP作为外部IP。

2 Namespace

与Tungsten Fabric集成时，Kubernetes命名空间（namespace）可以映射到项目/租户（project/tenant）或虚拟网络。

2.1 单租户（Single-tenant）

如果有设置/etc/contrail/contrail-kubernetes.conf中的[KUBERNETES].cluster_project，它是单租户（single-tenant），Kubernetes命名空间将映射到Tungsten Fabric中的虚拟网络。所有非隔离命名空间都映射到默认虚拟网络“cluster-network”。而每个隔离命名空间都映射到一个单独的虚拟网络“-vn”。

这里有一个示例，说明在/etc/contrailctl/kubemanager.conf中设置[KUBERNETES].cluster_project以启用单租户的情形。

[KUBERNETES]cluster_project = {'domain': 'default-domain', 'project': 'kubernetes'}

以下是由Condir-kube-manager在初始化期间创建的。

Flat IPAM ：具有子网的pod-ipam
IPAM ：service-ipam
虚拟网络“cluster-network”的安全组k8s-default-default-default和k8s-default-default-sg
虚拟网络：具有pod-ipam和service-ipam的cluster-network

（参见附录A.1）

2.1.1 非隔离的命名空间

创建一个非隔离的命名空间。

apiVersion: v1kind: Namespacemetadata: name: "dev-unisolated"

当Kubernetes创建一个非隔离命名空间时，Tungsten Fabric将创建两个SG，即k8s-default--sg和k8s-default--sg。这里不创建虚拟网络。所有非隔离的NS中的容器都将位于cluster-network上。

在非隔离命名空间中启动一个Pod。

apiVersion: v1kind: Podmetadata:  name: nginx-1spec:  containers:  - name: nginx    image: docker.io/nginx    imagePullPolicy: IfNotPresentkubectl create -f nginx-1.yaml -n kubectl get pods -n

在非隔离命名空间中启动Pod时，Tungsten Fabric（contrail-kube-manager）将执行以下操作。

不同非隔离命名空间中的Pod可以相互连接，因为它们位于Tungsten Fabric中的同一虚拟网络上。

2.1.2 隔离的命名空间

创建一个隔离的命名空间。

apiVersion: v1kind: Namespacemetadata: name: "dev-isolated" annotations: {   "opencontrail.org/isolation" : "true" }

在Kubernetes中创建隔离命名空间时，Tungsten Fabric将创建以下内容。

虚拟网络:-vn
安全组k8s-default--default和k8s-default--sg

在隔离命名空间中启动Pod时，Tungsten Fabric将执行以下操作。

由于端口位于不同的虚拟网络上，因此不同的隔离命名空间中的Pods无法相互连接。

2.2 多租户（Multi-tenant）

如果未设置/etc/contrail/contrail-kubernetes.conf中的[KUBERNETES].cluster_project，它就是多租户，Kubernetes命名空间将映射到Tungsten Fabric中的租户/项目（tenant/project）。非隔离命名空间中的Pod在默认虚拟网络“cluster-network”上启动。而每个隔离命名空间都映射到一个单独的虚拟网络“-vn”。

在初始化时，contrail-kube-manager创建以下内容：

为每个现有的Kubenetes命名空间（如default、kube-public和kube-system）提供一个项目/租户。
Flat IPAM 默认域：default:pod-ipam
IPAM 默认域：default:service-ipam
每一个命名空间的安全组：k8s-default--sg和k8s-default--sg
虚拟网络默认域名：具有pod-ipam的default:cluster-network和service-ipam

2.2.1 非隔离的命名空间

创建一个非隔离的命名空间。

apiVersion: v1kind: Namespacemetadata: name: "dev-unisolated"

Contrail-kube-manager将创建以下内容。

当在非隔离命名空间中启动Pod时，conventil-kube-manager将创建端口：

不同非隔离命名空间中的Pod可以相互连接，因为它们位于Tungsten Fabric中的同一虚拟网络上。

2.2.2 隔离的命名空间

创建一个隔离的命名空间。

apiVersion: v1kind: Namespacemetadata: name: "dev-isolated" annotations: {   "opencontrail.org/isolation" : "true" }

Contrail-cube-manager将创建以下内容。

项目缺省域：
虚拟网络default-domain::-vn与default-domain:default:pod-ipam关联。
安全组default-domain::k8s-default--default和default-domain::k8s-default--sg

当在非隔离命名空间中启动Pod时，conventil-kube-manager将创建端口。

在项目default-domain:中
在虚拟网络default-domain::-vn上
从IPAM default-domain:default:pod-ipam获取地址
附带安全组default-domain::k8s-default--default和default-domain::k8s-default--sg

由于端口位于不同的虚拟网络上，因此不同的隔离命名空间中的Pods无法相互连接。

2.3 自定义命名空间

创建一个自定义命名空间。

apiVersion: v1kind: Namespacemetadata: name: "dev-customized" annotations: {   "opencontrail.org/network": '{"domain": "default-domain", "project": "demo", "name": "red"}' }

在自定义命名空间中启动Pod时，contrail-kube-manager将创建端口。

在项目default-domain:default中
在虚拟网络上映射到自定义命名空间
从与该虚拟网络关联的IPAM上获取地址
安全组？

2.4指定虚拟网络上的Pod

在指定的虚拟网络上启动Pod。

当在指定的虚拟网络上启动Pod时，conutil-kube-manager将创建端口。

在项目中映射到指定或默认的命名空间
在指定的虚拟网络上
从与特定虚拟网络关联的IPAM上获取地址
安全组？

2.5 Kubernetes网络策略

Kubernetes网络策略将照常运行，它由Tungsten Fabric中的安全组实现。该版本将与4.0.1一起发布。

2.6 POD SNAT

Tungsten Fabric支持该功能，可以在Tungsten Fabric中配置一个路由器（配置对象），使其成为启动容器的虚拟网络的外部网关。这与支持OpenStack的外部网关是一样的。

3 Service

Kubernetes service支持ClusterIP，NodePort，LoadBalancer和ExternalName。它还支持使用ExternalIP指定IP。Tungsten Fabric支持ClusterIP和LoadBalancer，以及ExternalIP。

在Kubernetes中创建service时，Tungsten Fabric中会创建一个负载均衡器（loadbalancer）。负载均衡器的提供者为“native”，而ECMP负载均衡由vRouter实现。浮动IP被创建为VIP。

创建具有多个实例的应用程序。

apiVersion: v1kind: ReplicationControllermetadata:  name: web-qaspec:  replicas: 2  selector:    app: web-qa  template:    metadata:      name: web-qa      labels:        app: web-qa    spec:      containers:      - name: web        image: docker.io/nginx        imagePullPolicy: IfNotPresent

3.1 ClusterIP

在这些应用程序前面创建service。默认的service类型是ClusterIP。

kind: ServiceapiVersion: v1metadata:  name: web-qaspec:  selector:    app: web-qa  ports:    - protocol: TCP      port: 80      targetPort: 80

当service被创建后，conventil-kube-manager将执行以下操作。

当LB被创建后，“原生”LB驱动程序将执行以下操作。

在FIP中设置端口映射。
将所有成员的VMI添加到FIP。

当service类型为ClusterIP时，只能在集群内访问该service。FIP从集群网络（cluster-network）中的service FIP池中分配，并映射到所有的Pod地址。当访问集群内的service地址时，vRouter将在Pod之间平衡流量。

3.2 Loadbalancer

创建一个LoadBalancer类型的service。

kind: ServiceapiVersion: v1metadata:  name: web-qaspec:  selector:    app: web-qa  ports:    - protocol: TCP      port: 80      targetPort: 80  type: LoadBalancer

对于服务类型LoadBalancer，服务被暴露于外部。从服务FIP池中分配FIP，用于集群内的访问，同时从公共FIP池中分配FIP，映射到所有POD地址。该FIP将被通告给网关，网关将在POD之间进行ECMP负载均衡。
