docker build速度过慢问题_docker build很慢

docker速度过慢的原因在于，docker的默认源主要是在国外，因此会慢，解决办法是替换掉它.

我这里使用的是阿里的源：

RUN sed -i "s/archive.ubuntu./mirrors.aliyun./g" /etc/apt/sources.list
RUN sed -i "s/deb.debian.org/mirrors.aliyun.com/g" /etc/apt/sources.list
RUN sed -i "s/security.debian.org/mirrors.aliyun.com\/debian-security/g" /etc/apt/sources.list
RUN sed -i "s/httpredir.debian.org/mirrors.aliyun.com\/debian-security/g" /etc/apt/sources.list

python 的pip也替换成国内的阿里源

RUN pip install -U pip
RUN pip config set global.index-url http://mirrors.aliyun.com/pypi/simple
RUN pip config set install.trusted-host mirrors.aliyun.com

以上命令均写在Dockerfile中.
