本文使用的环境是：

获得nsenter

如果已经存在镜像压缩包 先解压再运行

erichan@ubuntu14_04_1-pd:~/docker-tars$ d load -i nsenter.tarerichan@ubuntu14_04_1-pd:~/docker-tars$ d run -v /usr/local/bin:/target jpetazzo/nsenter

如果本地没有 直接运行docker命令 从云端下载

erichan@ubuntu14_04_1-pd:~/docker-tars$ d run -v /usr/local/bin:/target jpetazzo/nsenterInstalling nsenter to /targetInstalling docker-enter to /target

调试

获得已经运行的容器进程号

erichan@ubuntu14_04_1-pd:~/docker-tars$ PID=$(d inspect --format {
   {.State.Pid}} sinopia)

sinopia 是运行中的容器进程的别名

使用nsenter进入该名字空间

erichan@ubuntu14_04_1-pd:~/docker-tars$ sudo nsenter --target $PID --mount --uts --ipc --net --pid

进入已经运行的容器中 调试环境已经搭好
