github - 用于从git克隆的构建代码的Docker文件

Question

我已经从github克隆了FreeCAD的副本，并且试图创建一个docker文件，以便可以在我的机器上本地开发它。

目标是:

我的机器上有git代码的本地副本

我可以修改代码

我可以构建调试并释放镜像(我需要创建两个单独的镜像吗？)

可以访问我机器上的代码，以便可以将git用于源代码控制

这是我的Dockerfile的内容:

# Get base image
FROM phusion/baseimage

# Use baseimage-docker's init system.
CMD ["/sbin/my_init"]

# Get the build pre-requisites
RUN apt-get update
RUN apt-get install -y build-essential cmake python python-matplotlib libtool
RUN apt-get install -y libcoin80-dev libsoqt4-dev
RUN apt-get install -y libxerces-c-dev libboost-dev libboost-filesystem-dev
RUN apt-get install -y libboost-regex-dev
RUN apt-get install -y libboost-program-options-dev libboost-signals-dev

# to make Coin to support additional image file formats
RUN apt-get install -y libsimage-dev

# to register your installed files into your system's package manager, so yo can easily uninstall later
RUN apt-get install -y checkinstall

# needed for the 2D Drafting module
RUN apt-get install -y python-qt4 python-pivy

#  doxygen and libcoin80-doc (if you intend to generate source code documentation)
RUN apt-get install -y doxygen libcoin80-doc

# libspnav-dev (for 3Dconnexion devices support like the Space Navigator or Space Pilot)
RUN apt-get install -y libspnav-dev

# CMAke related issue for compiling on Ubuntu Xenial: http://forum.freecadweb.org/viewtopic.php?f=4&t=16292
RUN apt-get install -y libmedc-dev
RUN apt-get install -y libvtk6-dev
RUN apt-get install -y libproj-dev

# Get git
RUN apt-get install -y git

RUN git clone https://github.com/FreeCAD/FreeCAD.git freecad

RUN cd freecad
RUN mkdir freecad-debug
RUN cd freecad-debug
# command below is just a diagnostic to let me know wth I am (output is: /)
# RUN pwd
RUN cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug .
#cmake -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Release .
RUN make

我尝试使用以下命令构建镜像:
docker build -tag freeCAD-my-fork .
一切正常，直到我进行第一个cmake调用。然后，我得到以下错误:

CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
The command '/bin/sh -c cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug .' returned a non-zero code: 1

我在Dockerfile中放置了一个 RUN pwd，因此我可以找到cmake命令的运行位置，而我惊讶地发现它是从根目录运行的。

我认为问题是由我使用relative引起的，并且可以通过绝对路径解决-但是在克隆等时指定 /path/to/my/copy/freecad，问题仍然存在。

如何编写Dockerfile，以实现上面概述的目标(在问题开始时说明)？

Answer 1

docker中的默认WORKDIR是“/”。所有docker命令都将在该目录中执行。更改WORKDIR(https://docs.docker.com/engine/reference/builder/#workdir)或在一层中执行所有操作(在一个RUN命令中)有两种选择。我采用了第二种方法。

克隆和构建源代码都在Docker的一层中执行。

RUN git clone https://github.com/FreeCAD/FreeCAD.git freecad \
&& cd freecad \
&& mkdir freecad-debug \
&& cd freecad-debug \
&& cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug . \
&& make
