Docker in my eyes (1) docker, vm, lxcPreface
What is docker? What can docker do? Why is docker so popular? I believe many people have this question. I also have. I think docker involves too many technologies. From the linux kernel

How to create and manage LXC containers on Ubuntu?
Although the concept of containers was introduced more than a decade ago to securely manage shared host hosting environments such as FreeBSD prison ), however, Linux, such as LXC and Docker, has recently entered the mainstream because of the increasing need to deploy applications for cloud computing. Despite the
"Containers" are used to secure the host environment, a concept that existed a decade ago (for example, FreeBSD's jail virtualization technology), but until recently, as the deployment of cloud architectures became more demanding, containers such as LXC and Docker were the focus of attention. Of course, thanks to the powerful backers of mainstream manufacturers (such as Amazon's main push AWS, Microsoft's m

LXC container Virtualization
After some tossing, I initially deployed LXC virtual on my work notebook. This is a very lightweight virtual solution, especially suitable for testing environments with limited hardware and a good environment for our system administrator technical training.

The following installation pr
the execution driver of Docker container, is responsible for creating container running namespace, responsible for statistics and restriction of container resource usage, and responsible for the real running of process inside container. In the implementation of the Execdriver, it was possible to use the LXC driver to invoke the LXC interface to manipulate the co
What LXC can do:You can bind specific CPUs and memory to a container, assign a specific percentage of CPU time, IO time, limit the amount of memory that can be used (including memory and swap space), provide device access control, and provide an independent namespace (network, PID, IPC, MNT, UTS).The default LXC configuration is to isolate PIDs (process) SysV IPC (interprocess communication), and mount poin

Containers can provide lightweight virtualization to isolate processes and resources, without the need to provide command interpretation mechanisms and other complexities of full virtualization. This document describes the container tool Linux containers (lxc) step by step ). The author demonstrates how to set and use them.
Containers effectively divide resources managed by a single operating system into isolated groups to better balance confl
Linux containers,linux containers, containers, it can be imagined as a large jar of things, the jar mouth is large, it can be installed in many of the same shape, but small jars of different sizes. Professional words, called a container-based operating system-level virtualization technology. In this large container, there can be a lot of small containers, each container has a complete operating environment, such as a specific CPU, memory node, the allocated CPU time, IO time, limited memory size
The largest feature of lxc 1.0 is a non-privileged container. Through clever uidmap, the common users (UID and GID) of the physical machine are mapped to the root (uid = 0, gid = 0), greatly improving the lxc security.
Lxc 1.0 has requirements on the kernel and Python versions. Therefore, the following uses Ubuntu 14.04 as an example to create a non-privileged
