Steps to Create Linux Container

After my last post about Docker Project, i start testing Linux Container but this time for lxc which is another amazing Package and should be used, if you installed and follow my steps in Previous steps here  then you can use lxc command without any suffer of installation :)

lxc stand for Linux Container.

Now i will start to describe how to create container using this command 

You need to know when lxc installed, it's create file under /etc/lxc/ called default.conf this file should contain your network interface name and you need to add it.

docker0   Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::28ce:eeff:fe80:1fc8/64 Scope:Link
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
