docker~aspnetcore2.0镜像安装软件的加速器_.NET_编程开发_程序员俱乐部

一般对于安装软件加速时，我们大多数会选择阿里云，而对于aspnetcore2.0这个进项来说，由于使用的是Debian操作系统，所有我们要找到它对应的mirror列表，下面是我整理的一个sources.list加速列表，我们把它放在和Dockerfile相同的位置，在Dockerfile生成镜像时把它复制到里面去，替换之前的apt-update地址源即可。

source.list内容

deb http://mirrors.aliyun.com/debian wheezy main contrib non-free
deb-src http://mirrors.aliyun.com/debian wheezy main contrib non-free
deb http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free
deb http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free
deb-src http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free

然后我们对Dockerfile进行一些修改，在生成镜像时把它复制到镜像里

FROM microsoft/aspnetcore:2.0
ARG source
COPY sources.list /etc/apt/sources.list
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone
RUN apt-get update && apt-get -y install libgdiplus
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "SMS.dll"]

然后我们再去生成镜像，就会非常非常快了！

当然，你也可以不添加这个文件，而直接把文本覆盖到原来的source.list文件里

FROM microsoft/aspnetcore:2.0
ARG source

RUN echo "deb http://mirrors.aliyun.com/debian wheezy main contrib non-free \
deb-src http://mirrors.aliyun.com/debian wheezy main contrib non-free \
deb http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free \
deb-src http://mirrors.aliyun.com/debian wheezy-updates main contrib non-free \
deb http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free \
deb-src http://mirrors.aliyun.com/debian-security wheezy/updates main contrib non-free" > /etc/apt/sources.list

RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone
RUN apt-get update &&  apt-get install libgdiplus -y
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "Pilipa.SMS.dll"]

上面的做法也是完全没有问题的！

你要是在阿里云服务器上，那就是内网对内网，更快！
