Kubernetes与TF的集成
contrail-kube-manager和kube-api-server
Contrail CNI

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

[KUBERNETES]cluster_project = {'domain': 'default-domain', 'project': 'kubernetes'}
Flat IPAM
IPAM
虚拟网络“cluster-network”的安全组k8s-default-default-default和k8s-default-default-sg
虚拟网络

apiVersion: v1kind: Podmetadata: name: nginx-1spec: containers: - name: nginx image: docker.io/nginx imagePullPolicy: IfNotPresentkubectl create -f nginx-1.yaml -nkubectl get pods -n
创建虚拟机
在启动Pod的虚拟路由器中,添加对VM的引用。
参考以下内容,创建VMI
SG k8s-default-
SG k8s-default-
VN
在VN cluster-network中从pod-ipam分配IP地址(cluster IP)。Subnet UUID被指定为从Flat IPAM pod-ipam进行分配。
apiVersion: v1kind: Namespacemetadata: name: "dev-isolated" annotations: { "opencontrail.org/isolation" : "true" }
虚拟网络
安全组k8s-default-
创建虚拟机
在启动了Pod的虚拟路由器中,添加对VM的引用。
参考以下内容,创建VMI
SG k8s-default-
SG k8s-default-
VN
在VN
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-
虚拟网络默认域名:具有pod-ipam的default:cluster-network和service-ipam
apiVersion: v1kind: Namespacemetadata: name: "dev-unisolated"
项目default-domain:
在项目缺省域:
在虚拟网络缺省域:default:cluster-network
从IPAM缺省域:default:pod-ipam获取地址
附带安全组k8s-default-default-default和k8s-default-default-sg
apiVersion: v1kind: Namespacemetadata: name: "dev-isolated" annotations: { "opencontrail.org/isolation" : "true" }
项目缺省域:
虚拟网络default-domain:
安全组default-domain:
在项目default-domain:
在虚拟网络default-domain:
从IPAM default-domain:default:pod-ipam获取地址
附带安全组default-domain:
apiVersion: v1kind: Namespacemetadata: name: "dev-customized" annotations: { "opencontrail.org/network": '{"domain": "default-domain", "project": "demo", "name": "red"}' }
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?
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?

Service
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
kind: ServiceapiVersion: v1metadata: name: web-qaspec: selector: app: web-qa ports: - protocol: TCP port: 80 targetPort: 80
参照以下内容,创建LB VMI
SG k8s-default-
SG k8s-default-
VN
在VN cluster-network中从service-ipam分配LB IP地址(service IP)。不需要subnet UUID。
创建负载均衡器
VIP是LB IP地址
VMI是LB VMI
提供者是“native”
创建浮动IP作为LB IP的子IP,地址相同,利用FIP支持端口NAT。
创建LB侦听器
创建LB池
创建LB成员
在FIP中设置端口映射。
将所有成员的VMI添加到FIP。
kind: ServiceapiVersion: v1metadata: name: web-qaspec: selector: app: web-qa ports: - protocol: TCP port: 80 targetPort: 80 type: LoadBalancer
