【问题描述】：
我正在尝试在我的 Mac 上将单个 Web 应用程序部署到 Minikube，然后在浏览器中访问它。我正在尝试使用最简单的设置，但它不起作用，我只是收到“连接被拒绝”错误，我不知道为什么。
这就是我正在尝试的：
$ minikube start --insecure-registry=docker.example.com:5000
???? minikube v1.12.3 on Darwin 10.14.6
✨ Using the docker driver based on existing profile
???? Starting control plane node minikube in cluster minikube
???? Restarting existing docker container for "minikube" ...
???? Preparing Kubernetes v1.18.3 on Docker 19.03.8 ...
???? Verifying Kubernetes components...
???? Enabled addons: default-storageclass, storage-provisioner
???? Done! kubectl is now configured to use "minikube"
$ eval $(minikube -p minikube docker-env)
$ docker build -t web-test .

$ minikube ssh
docker@minikube:~$ curl 10.102.19.201:8080
Up and Running
docker@minikube:~$
如您所见，Web 应用程序已启动并正在运行，我可以通过 minikube ssh 从集群内部访问它，但从集群外部，它不会连接。这些是我的服务和部署清单：
web-test-service.yaml:
apiVersion: v1
kind: Service
metadata:
labels:
app: web-test
name: web-test
spec:
type: NodePort
ports:
- nodePort: 31317
port: 8080

web-test-deployment.yaml：

有人知道我做错了什么吗？或者也许我可以尝试进一步诊断问题？我已经允许尝试部署一个入口，但这也不起作用。
【问题讨论】：
-
你可以试试
minikube service web-test -
谢谢 Arghya - 这似乎工作谢谢。但是，我担心为什么标准方法不起作用，以及是否存在阻止我部署到远程集群的问题，例如k3s.
-
在我的情况下，是
curl在访问minikube service web-test --url输出的地址时被阻止，而是访问浏览器中的url。
