Linux Namespace Learning Tutorial (1) UTS

[Editor's Note] The problem with the Docker core is to use LXC to implement VM-like functionality, thus using more cost-effective hardware resources to provide users with more computing resources. The LXC implementation of the isolation is mainly from the kernel's namespace, where pid, net, ipc, mnt, uts and other namespace will be the container process, […]
