如何在docker中编译使用内核函数的C代码，在容器中使用pci设备

Question

我有一个Makefile一些使用PCI设备的c++代码

all:
    g++ -o executable main.cpp dragon.pb.cc -std=c++11 -O3 -I/usr/include/postgresql -I/usr/include/hiredis -lzmq -lprotobuf -lpthread -lpq -lhiredis

clean:
    rm executable

并且它依赖于使用内核函数的C库。这个库的Makefile是

    # dist and build are folders, not phony targets
.PHONY: all package clean
all: dragon.pb.cc dragon_pb2.py package
dragon.pb.cc: dragon.proto
    protoc --cpp_out=. dragon.proto
dragon_pb2.py: dragon.proto
    protoc --python_out=. dragon.proto
package: build
clean:
    rm -f dragon.pb.*
    rm -f dragon_pb*
    rm -rf build
    rm -rf dist
    rm -f MANIFEST

这是我的Dockerfile

FROM ubuntu:14.04
ENV PG_MAJOR 9.3
RUN apt-get update
RUN apt-get install -y git make protobuf-compiler libhiredis-dev postgresql-server-dev-${PG_MAJOR}
RUN apt-get install -y g++
RUN apt-get install -y libzmq-dev
RUN apt-get install -y libprotobuf-dev
RUN apt-get install -y linux-headers-$(uname -r)
ADD deployment_key /root/.ssh/id_rsa
RUN chmod 600 /root/.ssh/id_rsa

RUN echo "StrictHostKeyChecking no" >> /root/.ssh/config
RUN echo >> /root/.ssh/config
RUN echo "Host bitbucket.org" >> /root/.ssh/config

RUN mkdir -p /usr/src/app/
WORKDIR /usr/src/app/
RUN git clone [e-mail]:opticsdevelopment/dragon-protocols.git
WORKDIR ./dragon-protocols
RUN make dragon.pb.cc
RUN cp ./dragon.pb.* ../
COPY . /usr/src/app
WORKDIR ../
RUN git clone [e-mail]:opticsdevelopment/dragon-module.git
WORKDIR ./dragon-module
RUN make all
WORKDIR ../
RUN make
EXPOSE 5570
CMD ["dragon"]

现在的问题是在安装linux-headers。它找不到头文件

E: Unable to locate package linux-headers-3.13.0-19-generic
E: Couldn't find any package by regex 'linux-headers-3.13.0-19-generic'

Answer 1

如果你的应用程序可以编译任何通用的linux头文件

在你的Dockerfile变化

RUN apt-get install -y linux-headers-$(uname -r)

RUN apt-get install -y linux-headers-generic 

或者如果您需要与主机系统相同的特定属性为什么不直接用-v把这个目录从主机卷链接到docker容器呢?

:

sudo apt-get install linux-headers-$(uname -r)

/usr/src/linux-headers-$(uname -r)/include

现在在你的docker容器上运行命令，链接卷，像

-v /usr/src/linux-headers-$(uname -r)/include:/usr/src/linux-headers-$(uname -r)/include
