curl:(7)无法连接到192.168.99.100端口31591:连接被拒绝 [英] curl: (7) Failed to connect to 192.168.99.100 port 31591: Connection refused

问题描述

这些是我的豆荚

hello-kubernetes-5569fb7d8f-4rkhs   0/1     ImagePullBackOff   0          5d2h
hello-minikube-5857d96c67-44kfg     1/1     Running            1          5d2h
hello-minikube2                     1/1     Running            0          3m24s
hello-minikube2-74654c8f6f-trrrw    1/1     Running            0          4m8s
hello-newkubernetes                 0/1     ImagePullBackOff   0          5d1h

如果我尝试

curl $(minikube service hello-minikube2 --url)
curl: (7) Failed to connect to 192.168.99.100 port 31591: Connection refused

让我们检查一下VBox

Let's check VBox

inet 192.168.99.1/24 brd 192.168.99.255 scope global vboxnet0
   valid_lft forever preferred_lft forever
inet6 fe80::800:27ff:fe00:0/64 scope link 
   valid_lft forever preferred_lft forever

为什么我的连接被拒绝?

Why is my connection refused?

tomcat-deployment   172.17.0.6:8080                   11h

我想显示服务端点

minikube service tomcat-deployment --url
http://192.168.99.100:30613

为什么该网址与get ep -o wide输出不同?

Why is this url different from get ep -o wide output?

推荐答案

显然，您正在尝试在群集外部访问服务，因此您需要公开服务IP以进行外部连接.

Apparently, you are trying to reach your service outside of the cluster, thus you need to expose your service IP for external connection.

运行kubectl edit svc hello-minikube2并更改

type: NodePort

到

type: LoadBalancer

或

kubectl expose deployment hello-minikube2 --type=LoadBalancer --port=8080

在支持负载平衡器的云提供商上，将提供一个外部IP地址来访问服务.在Minikube上，LoadBalancer类型使服务可以通过minikube service命令访问.

On cloud providers that support load balancers, an external IP address would be provisioned to access the Service. On Minikube, the LoadBalancer type makes the Service accessible through the minikube service command.

运行以下命令:

minikube service hello-minikube2
