dotnetcore docker 简单运行

今天试用了下mac 版本的dotnetcore sdk，发现还是很方便的，同时官方的容器运行方式，相对小了好多
同时使用多阶段构建的方式运行dotnetcore

安装sdk

下载地址：
https://dotnet.microsoft.com/download
选择版本下载并安装即可

简单demo

使用dotnetcore 命令创建的

• 创建简单demo

mkdir app

cd dotnet new mvc 

• 生成发布文件

dotnet publish -c Release -o out

集成docker

• docker-compose 文件

version: "3"

services: 

  app:

    build: 

      context: ./

      dockerfile: Dockerfile

    image: dalongrong/dotnetcoreaspnet-demo:alpine

    ports: 

    - "80:80"

  app-build:

    build: 

      context: ./

      dockerfile: Dockerfile-multistage

    image: dalongrong/dotnetcoreaspnet-demo2:alpine

    ports: 

    - "8080:80"

• Dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-alpine

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

WORKDIR /app

COPY /app/out /app/

EXPOSE 80

ENTRYPOINT [ "dotnet","/app/app.dll" ]

• 几点说明
  使用多阶段构建方式，需要注意顺序，可以参考连接 https://docs.docker.com/engine/examples/dotnetcore/，这点和官方的有出入

 

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build

WORKDIR /app

COPY app/*.csproj ./

RUN dotnet restore -s https://api.nuget.org/v3/index.json

COPY app/. /app/

RUN dotnet publish -c Release -o out

​

FROM mcr.microsoft.com/dotnet/core/aspnet:2.2-alpine

LABEL AUTHOR="dalongrong"

LABEL EMAIL="1141591465@qq.com"

WORKDIR /app

COPY --from=build /app/out .

EXPOSE 80

ENTRYPOINT [ "dotnet","app.dll" ]

 

 

对于aspnet 运行时环境我使用的alpine 这样稍小点

启动&&效果

• 启动

docker-compose up  -d

• 效果
