我正在尝试创建一个用于armhf交叉编译的docker容器。
我一直在https://wiki.debian.org/CrossToolchains关注指南，根据我的理解，下面的Dockerfile就足够了。不幸的是，它找不到gcc-arm-linux-gnueabihf和g ++-arm-linux-gnueabihf依赖项。
FROM debian:jessie
# Install curl so that we can download the keys
RUN apt-get update && apt-get install -y curl
RUN echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
RUN curl http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
RUN dpkg --add-architecture armhf
RUN apt-get update && apt-get install -y cross-gcc-dev
RUN apt-get install -y crossbuild-essential-armhf
BUILD：
sudo docker build .

有人可以指出我正确的方向吗？我知道还有其他容器已经进行了交叉编译，但对我来说创建自己的容器非常重要。
