Nginx + Docker 多階段構建的部署學習

　　前幾天部署了一個網站，原來我一直是發佈完成之後，通過ftp把文件上傳上去，有幾個大佬給我說了多階段構建，此時我就不需要發佈再搞了，直接將項目添加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幾個COPY ，只要是和你這個項目有依賴的，統統打包，構建成一個鏡像。

然後就是Nginx了，配置文件如下。那個埠對準1314的埠必須是docker的外網埠！

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;
        }
    }
}

此時訪問39.104.53.29 就可以訪問到docker對外開放的1314 對內5001的網站了。
