【Azure Developer】已釋出好的.NET Core專案檔案如何打包為Docker映象檔案
問題描述
在博文(【Azure App Service For Container】建立ASP.NET Core Blazor專案並打包為Linux映象釋出到Azure應用服務)中我們通過VS 2019可以為專案新增Dockerfile並自動生成Docker Image檔案。但是如果不借助於VS2019我們如何來操作呢?
解決步驟
準備Dockerfile
進入專案資料夾中,建立Dockerfile並COPY以下內容:
#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging. #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. #For more information, please see https://aka.ms/containercompat FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build ENV ASPNETCORE_URLS=http://+:8000
WORKDIR /app EXPOSE 8000 EXPOSE 5000 COPY . /app/ ENTRYPOINT ["dotnet", "MyLife.Blazor.Server.dll"]
- FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base 和 FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build 可以在Docker Hub中查詢到對於的版本映象(https://hub.docker.com/_/microsoft-dotnet-sdk)
- COPY . /app/ 即把dockerfile所在的目錄中所有檔案複製到映象中app目錄中
生成映象
通過CMD進入到當前目錄, 使用 docker build -t mywebimages . (特別注意:在命令中必須要點.,黃色高亮的部分替代為自定義的映象名。詳細的命令參考Docker說明:https://docs.docker.com/engine/reference/commandline/build/)
當命令執行完成後,在Docker Desktop頁面中可以看見當前Images
執行映象,驗證專案執行成功
在Docker Desktop中Run當前Image或者通過docker run命令啟動Container: docker run --name testweb -p 8080:8000 mywebimages
命令啟動輸出:
C:\MyCode\MyLife\MyLife.Blazor\MyLife.Blazor\Server\bin\Release\net5.0\publish>docker run --name testapidemo -p 8080:8000 mywebimages |
訪問Docker Container指定的埠8080結果為:
