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
(CPU, memory, Disk input and output, etc.) and associate these types of resources to the Cgroup specified in the hierarchy to implement the resource allocation.Note: Cgroups is the underlying foundation of the Resource Management Control section for IaaS virtualization (KVM, LXC, etc.), PAAs container sandbox (docker, etc.)

Lxc is abbreviated as Linux containers. It is an operating system-level virtualization technology, which is a user space interface for Linux kernel container functions. It packs an application software system into a software container containing the Code of the application software and the required oper

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 to various cloud computing solutions, it is a little difficult for me. However, after learning about docker for a month, I still want to talk about it briefly. I hope it will be helpful for beginners of docker.Docker history

LXC, also known as Linux container, is a virtualized solution, which is a kernel-level virtualization. (Main solutions Xen, KVM, LXC)Introduced
By namespace resource isolation, the process under Gust1 is independent of the process under Guset2 and can be seen as running on two physical machines. The Contaniner management tool is the management of guest (cre
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.

Libvirt can manage qemu and lxc, but commands are complicated during execution management, such as viewing the status of qemu virtual machines.

Libvirt is able to manage qemu and LXC but commands are more complex when performing management, such as viewing qemu virtual machine status

Background: Because of job testing needs, testing software features on different hosts, but no separate virtual machines can be used, think of using LXC for lightweight virtualization. The LXC virtual machine chooses the virtual Macvlan NIC on the host for use by the virtual machine.

access the Linux namespace and the Cgroup kernel. Before installing Nsinit, you first need to install the GO Runtime environment:
$ apt-get installgit golang-go
$ mkdir-p $HOME/go-dev/binmkdir-p $HOME/go-dev/src
$ echo "Export gopath=\ $HOME/ Go-dev ">> ~/.profileecho" path=\ $PATH: \ $GOPATH/bin ">> ~/.profile
$ source~/.profile
Next Install Nsinit:
$ apt-get installgit golang-go
$ mkdir-p $HOME/go-dev/binmkdir-p $HOME/go-dev/src
$ echo "Export gopath
