Несколько версий ядра dotnet на образе Linux-докера

Question

Я хочу знать, как я могу запустить и установить несколько версий ядра dotnet core Framework 2.1 и 1.1 в Docker-контейнере на Linux. Ниже мой текущий dockerfile, и я хочу добавить к нему dotnet 1.1

FROM microsoft/dotnet:2.1.403-sdk-bionic

ENV DOTNET_SKIP_FIRST_TIME_EXPERIENCE true
ENV DOTNET_CLI_TELEMETRY_OPTOUT true

RUN apt-get update && \
    apt-get install -y zip  

Answer 1

Вот пример структуры ядра с несколькими точками.

FROM microsoft/dotnet:2.2-runtime-deps-stretch-slim

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        curl \
        wget \
        gpg \
        apt-transport-https \
    && rm -rf /var/lib/apt/lists/*

RUN apt-get update

# Install .NET Core Runtime v1.1.2
ENV DOTNET_VERSION 1.1.2
ENV DOTNET_DOWNLOAD_URL https://dotnetcli.blob.core.windows.net/dotnet/release/1.1.0/Binaries/$DOTNET_VERSION/dotnet-debian-x64.$DOTNET_VERSION.tar.gz

RUN curl -SL $DOTNET_DOWNLOAD_URL --output dotnet.tar.gz \
    && mkdir -p /usr/share/dotnet \
    && tar -zxf dotnet.tar.gz -C /usr/share/dotnet \
    && rm dotnet.tar.gz \
    && ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet

# Install ASP.NET Core
ENV ASPNETCORE_VERSION 2.2.1
RUN curl -SL --output aspnetcore.tar.gz https://dotnetcli.blob.core.windows.net/dotnet/aspnetcore/Runtime/$ASPNETCORE_VERSION/aspnetcore-runtime-$ASPNETCORE_VERSION-linux-x64.tar.gz \
    && aspnetcore_sha512='e027a5dada5d139a44675f28090f996375e49fbd72f7897aa925e48803632d5bf187d4f22dc8225505ac33e6a7a05dcdd8ed19d8b6d5e46b22e628315cf13e3e' \
    && echo "$aspnetcore_sha512  aspnetcore.tar.gz" | sha512sum -c - \
    && mkdir -p /usr/share/dotnet \
    && tar -zxf aspnetcore.tar.gz -C /usr/share/dotnet \
    && rm aspnetcore.tar.gz \
    && ln -sf /usr/share/dotnet/dotnet /usr/bin/dotnet

А вот результат из экземпляра
