在高山码头工人中找不到 dotnet

Question

我有以下 dockerfile：

FROM jenkins/jenkins:lts-alpine

USER root

RUN apk update
RUN apk add bash icu-libs krb5-libs libgcc libintl libssl1.1 libstdc++ zlib wget
RUN apk add libgdiplus --repository https://dl-3.alpinelinux.org/alpine/edge/testing/

USER jenkins

RUN wget https://dot.net/v1/dotnet-install.sh -O $HOME/dotnet-install.sh
RUN chmod +x $HOME/dotnet-install.sh
RUN $HOME/dotnet-install.sh -c 5.0

RUN dotnet --info

EXPOSE 2376 23676

但是当我运行 docker-compose 时，它​​给了我：

我遵循了 Microsoft 文档中的每一步，但总是失败。我在这里做错了什么？

使用jenkins/jnlp-slave:alpine图像

FROM jenkins/jnlp-slave:alpine

USER root

RUN apk add bash icu-libs krb5-libs libgcc libintl libssl1.1 libstdc++ zlib wget
RUN apk add libgdiplus --repository https://dl-3.alpinelinux.org/alpine/edge/testing/

RUN mkdir -p /usr/share/dotnet \
    && ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet 

RUN wget https://dot.net/v1/dotnet-install.sh
RUN chmod +x dotnet-install.sh
RUN ./dotnet-install.sh -c 3.1 --install-dir /usr/share/dotnet
RUN ./dotnet-install.sh -c 5.0 --install-dir /usr/share/dotnet
RUN ./dotnet-install.sh -c 6.0 --install-dir /usr/share/dotnet
