Nginx + Docker 多阶段构建的部署学习

　　前几天部署了一个网站，原来我一直是发布完成之后，通过ftp把文件上传上去，有几个大佬给我说了多阶段构建，此时我就不需要发布再搞了，直接将项目添加docker支持。

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["amusinghoS.App/amusinghoS.App.csproj", "amusinghoS.App/"]
COPY ["amusinghoS.Entity/amusinghoS.EntityData.csproj", "amusinghoS.Entity/"]
COPY ["amusinghoS.Shared/amusinghoS.Shared.csproj", "amusinghoS.Shared/"]
COPY ["amusinghoS.Services/amusinghoS.Services.csproj", "amusinghoS.Services/"]
COPY ["amusinghoS.Redis/amusinghoS.Redis.csproj", "amusinghoS.Redis/"]
RUN dotnet restore "amusinghoS.App/amusinghoS.App.csproj"
COPY . .
WORKDIR "/src/amusinghoS.App"
RUN dotnet build "amusinghoS.App.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "amusinghoS.App.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "amusinghoS.App.dll"]

其中最重要的就是那几个COPY ，只要是和你这个项目有依赖的，统统打包，构建成一个镜像。

然后就是Nginx了，配置文件如下。那个端口对准1314的端口必须是docker的外网端口！

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include mime.types;
    default_type  application/octet-stream;
    sendfile on;
    keepalive_timeout  65;
    server {
        listen 80;
        server_name localhost;
        error_page 500 502 503 504 /50x.html;
        location / {
                proxy_pass http://39.104.53.29:1314;
                proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection keep-alive;
        proxy_set_header Host $http_host;
        proxy_cache_bypass $http_upgrade;
        }
    }
}
