使用阿里云容器镜像服务示例

构建镜像

Dockerfile文件内容，可以用VS2019直接生成，注意COPY路径和存放位置。

#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 ["WebAPI/WebAPI.csproj", "WebAPI/"]
COPY ["Common/Common.csproj", "Common/"]
RUN dotnet restore "WebAPI/WebAPI.csproj"
COPY . .
WORKDIR "/src/WebAPI"
RUN dotnet build "WebAPI.csproj" -c Release -o /app/build

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

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

拉取镜像

登录阿里云Docker Registry

$ sudo docker login --username=[你的阿里云用户名] registry.cn-qingdao.aliyuncs.com

用于登录的用户名为阿里云账号全名，密码为开通服务时设置的密码。
您可以在访问凭证页面修改凭证密码。
从Registry中拉取镜像

$ sudo docker pull registry.cn-qingdao.aliyuncs.com/zztnet/demo:[镜像版本号]

查看镜像
