LXC is a shorthand for Linux container. The Linux container container is a kernel virtualization technology that provides lightweight virtualization to isolate processes and resources without the need for instruction interpretation mechanisms and other complexities of full virtualization. Equivalent to namespace in C + +. Containers effectively divide resources managed by a single operating system into orphaned groups to better balance conflicting res

Core uses LXC (Linux namespace Container) technology and bridge technology to achieve virtual host and virtual network simulation. LXC uses the Process Group resource Management framework in the Cgroups subsystem to implement a virtual host as a relatively independent process for the same group.

B use 50% of resources. It can be seen that the function of cgroup is to limit resources rather than divide resources. For more information about how to operate cgroup commands and Subsystem Configuration files, seeHow to use cgroup [4]. 7. How can I quickly switch resource allocation after changing the container status? Modify the cgroup configuration file of the container. 8. Why is a user directory automatically created in each cgroup? -Ubuntu 14.04 Refer to the explanations in help.ubuntu

Quick understanding of Docker-container-level virtualization SolutionsSimply put , Docker is a lightweight VM solution built on top of LXC , based on process containers (processcontainer) By analogy with the transport of goods in the real world , in order to solve the problem of transporting goods of various types and sizes in various transport vehicles , we invented the container The purpose of Docker is to package applications and the running
