使Docker Container支持运行SWT程序
1, 下载安装JDK的docker container
我是从这个源下载已经做好的JDK8的container：
https://registry.hub.docker.com/u/dockerfile/java/
docker run -it --rm dockerfile/java:oracle-java8
2, 添加GUI支持
有好几种方案，我使用的是这种：

还有一种是：

我没有试过。
3，安装swt-gtk
但是这时候运行swt程序，还是会抛如下错误：
java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-gtk-3740 in java.library.path no swt-gtk in java.library.path Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk-3740.so
Can't load library: /home/gabriel/.swt/lib/linux/x86_64/libswt-gtk.so
需要：
1） 添加architecture i386
sudo dpkg --add-architecture i386
sudo apt-get update

http://askubuntu.com/questions/551840/unable-to-locate-package-libc6-dbgi386-in-docker
2）安装gtk
sudo apt-get install libgtk2.0-0:i386
参考：

3）安装swt支持
sudo apt-get install libswt-gtk-3-jni libswt-gtk-3-java
并拷贝到
sudo cp /usr/lib/jni/libswt-*3740.so ~/.swt/lib/linux/x86_64/
