kubernetes - Kubernetes入门-部署Docker Compose

Question

我正在尝试遵循本教程中的指示信息:https://docs.docker.com/docker-for-windows/kubernetes/#use-docker-commands。我已按照以下步骤操作:

1)在Docker Desktop中启用Kubernetes。

2)在Visual Studio 2019中创建一个简单的asp.net core 3.1应用程序，并添加容器编排支持(Docker Compose)。

3)在Visual Studio 2019中运行该应用程序，以确认它已在Docker中成功运行。

4)在DOS中运行以下命令:docker-compose build kubernetesexample
5)在DOS中运行以下命令:docker stack deploy --compose-file docker-compose.yml mystack
6)在DOS中运行以下命令:kubectl get services。结果如下:



如何浏览到我的应用程序？我尝试浏览到:http://localhost:5100和http://localhost:32442。

这是我的docker-compose.yml:

    services:
      kubernetesexample:
        environment:
          - ASPNETCORE_ENVIRONMENT=Development
        ports:
          - "45678:80"

Here is the result of running: kubectl get svc kubernetesexample-published -o yaml:

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: "2020-03-14T17:51:41Z"
  labels:
    com.docker.service.id: mystack-kubernetesexample

    com.docker.stack.namespace: mystack

  loadBalancer:
    ingress:
    - hostname: localhost

请注意，端口现已更改:

Answer 1

Service - An abstract way to expose an application running on a set of Pods as a network service.

而是使用Kubernetes文档。他们在浏览器中互动了示例。我看到您尝试使用 LoadBalancer，这必须在云提供商或正确设置的环境中得到支持。所有发布服务均为 here。尝试使用NodePort，简单的配置例如:

apiVersion: v1
kind: Service
metadata:
  name: np-kubernetesexample
  labels:
    app: kubernetesexample
spec:
  type: NodePort
  ports:
    port: 5100
    protocol: TCP
    targetPort: 5100
  selector:
    app: kubernetesexample

...根据我从提供的SC和说明中收集到的信息，请检查端口和标签。如果成功，当您键入 kubectl get services， xxxx:3xxxx/TCP时，应用程序应该在本地主机localhost:3xxxx上可用，该端口在PORTS下描述。
