Linux Container is a key open source of delivery technology along with application packaging. It also combines the lightweight application isolation and flexibility of image based set-up method. It is a service provided by the Linux. It runs in a completely isolated atmosphere on top of the kernel. The services of one container cannot be accessed from another due to the security features. Due to its popularity distributors are taking into consideration the container management.
These containers can be used on any Linux distribution and this is made possible by Systemd which is basically a service manager. It can manage cgroups and chroot which in turn helps the isolation containers to rely. nspawn is used in systemd to start containers and came into existence with Red Hat Linux 7.1.
A thorough study of Linux courses will make you more acquainted with the concept of Linux container and show you how to create an nspawn container by enabling the system-nspwan@service, which can be operated only against the backdrop where the service of the container is started.
