Kubernetes-Ingress与Minikube

Question

我通过玩迷你库贝来学习库伯内特。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-deployment
spec:
  replicas: 2
  selector:
    matchLabels:
      component: web
  template:
    metadata:
      labels:
        component: web
    spec:
      containers:
        - name: myapp
          image: myid/myimage

apiVersion: v1
kind: Service
metadata:
  name: my-ip-service
spec:
  type: NodePort
  externalIPs:
  - 192.168.99.100
  selector:
    component: web
  ports:
    - port: 3000
      nodePort: 30002
      targetPort: 8080

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-ingress
spec:
  backend:
    serviceName: my-ip-service
    servicePort: 3000

NAME           HOSTS   ADDRESS   PORTS   AGE
test-ingress   *                 80      41m

如何与Minikube一起使用ingress？或者如何将minikube ip与ingress服务绑定--这样就可以在不使用nodeport的情况下将应用程序公开到外部

Answer 1

您可以通过以下方式获取minikube节点的IP地址：

minikube ip

入口的IP地址将不会填充在minikube中，因为minikube缺少负载均衡器。如果您希望minikube集群具有负载均衡器的功能,https://github.com/knative/serving/blob/master/docs/creating-a-kubernetes-cluster.md#loadbalancer-support-in-miniKube建议运行以下命令为集群打补丁：

sudo ip route add $(cat ~/.minikube/profiles/minikube/config.json | jq -r ".KubernetesConfig.ServiceCIDR") via $(minikube ip)
kubectl run minikube-lb-patch --replicas=1 --image=elsonrodriguez/minikube-lb-patch:0.1 --namespace=kube-system
