（二）搭建dotNetCore项目发布到k8s

阅读之前请先参考博客：发布dotNetCore程序到Kubernetes

流程主要为 创建项目->打包项目->发布项目, 其它的基本都不重要

手动操作验证： 

项目为netCore 3.1版本

1.创建一个基本的netCoreApi 项目，能正常跑起来

2.项目右键-> 添加 -> Dockerfile 支持，自动生成Dockerfile 文件

3. Dockerfile 环境修改

mcr.microsoft.com/dotnet/core/aspnet:3.1-nanoserver-1903    ->   mcr.microsoft.com/dotnet/core/aspnet:3.1

mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1903   -> mcr.microsoft.com/dotnet/core/sdk:3.1 

 

 1 #See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
 2 
 3 #Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.
 4 #For more information, please see https://aka.ms/containercompat
 5 
 6 FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base
 7 WORKDIR /app
 8 EXPOSE 80
 9 
10 FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
11 WORKDIR /src
12 COPY ["k8s-netcore-demo.csproj", ""]
13 RUN dotnet restore "./k8s-netcore-demo.csproj"
14 COPY . .
15 WORKDIR "/src/."
16 #RUN dotnet build "k8s-netcore-demo.csproj" -c Release -o /app/build
17 
18 FROM build AS publish
19 #RUN dotnet publish "k8s-netcore-demo.csproj" -c Release -o /app/publish
20 
21 FROM base AS final
22 WORKDIR /app
23 #COPY --from=publish /app/publish .
24 ENTRYPOINT ["dotnet", "k8s-netcore-demo.dll"]
Dockerfile

4.构建打包项目

准备工作：

4.1 先拉取3.1版本环境镜像，如果没有，后续打包会有各种问题

docker pull mcr.microsoft.com/dotnet/core/aspnet:3.1 

docker pull mcr.microsoft.com/dotnet/core/sdk:3.1  

 4.2 打包项目

 

 

 4.3 推送到k8s上面

先创建好yaml发布配置文件 deploy.yaml

 1 apiVersion: apps/v1
 2 kind: Deployment
 3 metadata:
 4   name: k8s-netcore-demo
 5   namespace: k8s-netcore
 6   labels:
 7     k8s-app: k8s-netcore-demo
 8 spec:
 9   replicas: 1
10   selector:
11     matchLabels:
12       k8s-app: k8s-netcore-demo
13   template:
14     metadata:
15       labels:
16         k8s-app: k8s-netcore-demo
17     spec:
18       containers:
19       - name: k8s-netcore-demo
20         image: k8s-netcore-demo:v.202011291958
21         ports:
22         - containerPort: 80  
23 ---
24 # ------------------- Service ------------------- #
25 kind: Service
26 apiVersion: v1
27 metadata:
28   labels:
29     k8s-app: k8s-netcore-demo
30   name: k8s-netcore-demo
31   namespace: k8s-netcore
32 spec:
33   type: NodePort
34   ports:
35     - port: 80
36       targetPort: 80
37   selector:
38     k8s-app: k8s-netcore-demo
deploy.yaml

推送到k8s

k8s面板可查看相关信息

 最后就是访问项目

端口号可根据 kubectl get svc -n k8s-netcore  查看 CLUSTE-IP (4.3步操作)

 

 

 

常用命令：

 1 #创建dotNetCore项目
 2 dotnet new webApp -o k8s-netcore-demo --no-https
 3 #将dotNetCore程序构建为镜像
 4 docker build -t k8s-netcore-demo .
 5 #启动代理
 6 kubectl proxy
 7 #创建namespace
 8 kubectl create namespace k8s-netcore
 9 #部署Kubernetes
10 kubectl create -f deploy.yaml --validate
11 #删除Kubernetes
12 kubectl delete -f deploy.yaml
13 #迭代Kubernetes
14 kubectl apply -f deploy.yaml --record
15 #查看指定命名空间的部署情况
16 kubectl get deploy -n k8s-netcore
17 #查看指定命名空间的资源情况
18 kubectl get svc -n k8s-netcore
