Centos container on ubuntu.

Users can choose from a large number of distribution templates for their container including but not limited to ubuntu fedora debian red hat and centos. Docker is an open source and popular operating system level virtualization commonly known as containerization technology that primarily runs on linux and windows docker makes it easier to create deploy and run applications by using containers. In the above screenshot you can see that finally we got the ip address for our ubuntu install lxc linux containers. Our main focus is system containers.

Everything is set up its time to install some lxc templates which are basically a script to fetch and install the os images available on the lxc official website such as centos ubuntu alpine.
