kubernetes - curl : (7) Failed to connect to 192. 168.99.100 端口 30790:连接被拒绝

Question

我正在编写有关创建 Kubernetes 服务以指向大使部署的教程。

教程:https://www.bogotobogo.com/DevOps/Docker/Docker-Envoy-Ambassador-API-Gateway-for-Kubernetes.php

在运行命令时

curl $(minikube service --url ambassador)/httpbin/ip

我收到错误

curl: (7) Failed to connect to 192.168.99.100 port 30790: Connection refused
curl: (3) <url> malformed 

我实际上可以消除错误

curl: (3) <url> malformed

通过运行

minikube service --url ambassador
http://192.168.99.100:30790

进而

curl http://192.168.99.100:30790/httpbin/ip

我已经尝试过这个答案 curl: (7) Failed to connect to 192.168.99.100 port 31591: Connection refused这个答案中提到的步骤也已经在博客中，但它没有用。

这是来自博客的代码，用于 Ambassador-svc.yaml

---
apiVersion: v1
kind: Service
metadata:
  labels:
    service: ambassador
  name: ambassador
  annotations:
    getambassador.io/config: |
      ---
      apiVersion: ambassador/v0
      kind:  Mapping
      name:  httpbin_mapping
      prefix: /httpbin/
      service: httpbin.org:80
      host_rewrite: httpbin.org
spec:
  type: LoadBalancer
  ports:
  - name: ambassador
    port: 80
    targetPort: 80
  selector:
    service: ambassador

这可能是与VM相关的问题吗？

另外，我尝试在 this 上工作首先教程，但不幸的是，得到了同样的错误。

让我知道我这边是否还有其他需要。

kubectl get pods --namespace=kube-system

跑完之后

kubectl apply -f https://docs.projectcalico.org/v3.7/manifests/calico.yaml

Answer 1

kubectl 获取 pod --namespace=kube-system 应该有网络服务 pods
因此，您尚未设置用于 DNS 的网络策略。
尝试使用网络策略 Calico
通过使用命令
kubectl 应用 -f https://docs.projectcalico.org/v3.7/manifests/calico.yaml
立即查看 kubectl 获取 pod --namespace=kube-system
你应该得到这样的输出: -
