Cgroup IntroductionCgroup is the abbreviation for control group, which provides a mechanism for the task aggregation and partitioning of the Linux kernel, which organizes some tasks into one or more subsystems through a set of parameter sets.CGROUPS is the acronym for Control groups, originally presented by Google engineers and later compiled into the Linux kernel.Cgroups is the underlying foundation of the Resource Management Control section for IaaS virtualization (KVM,

Docker is an open-source application container engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Using Linux lxc, AUFS, go language, cgroup to realize the independence of resources, can easily realize the isolation of files, resources, networks, and its ultimate goal is to achieve similar PAAs platform application isolation.Docker's notable features: File system isolation: Each process

Including a variety of virtual machine technologies, KVM, Xen and LXC, can call the Libvirt provides the API to manage the virtual machine. With so much virtual machine technology, why does it provide so much

adding other virtualization technologies to the OpenStack cluster, it is necessary to consider carefully and comprehensively the difficulties and more complex architectures that it presents. at the beginning of Openstack design, the QEMU-KVM virtualization platform was the focus of support. However, a large number of enterprises have adopted other virtualization platforms, such as: Xen,esxi. And companies are reluctant to change existing IT infrastructure facilities, so OpenStack needs to suppo

1. Docker IntroductionDocker is based on the go language, followed by the apache2.0 protocol, all source code on the GIT maintenance of open-source projects. The Docker engine is based on the Linux container (LXC) technology. Docker technology can be understood as one of the virtualization technologies, but Docker has significant differences and advantages over the traditional virtual machine approach in running the application: Docker contai

Before trying to play Docker for a while, today is the first time to formally deploy network services in Docker.Originally want and lxc similar things that nature is extremely easy, didn't think or changed a lot.The first problem encountered was that the remote connected to the Docker host was suddenly disconnected from the network. A silly drop, used to be even the intranet, has never been. This time even a reverse tunnel, incredibly broken, dumbfoun

Recently, the stable version of docker1.0 is released, which injects fresh blood into Paas. Docker is a powerful automated Distributed System: large-scale Web deployment, database clusters, continuous deployment systems, private paas, and service-oriented architecture. Docker is a Linux XC iner (lxc) technology that adds advanced APIs and provides a lightweight virtualization solution that can run Unix processes independently. It provides a way to aut

Control groups (control group) The key to running an application in isolation is to control the application to use legal resources. This ensures that the container is a good multi-tenant user on the host machine. The control group allows docker to share the hardware resources of the host to the container, and suppor

/CentOS must be version 6.6 or later, or 7. x to install docker. We recommend that you use docker on RedHat/CentOS 7 because the kernel of RedHat/CentOS 7 is upgraded to kernel 3.10, which provides better support for lxc containers.Centos6.6 install docker rpm -ivh http://mirrors.yun-idc.com/epel/6Server/x86_64/epel-release-6-8.noarch.rpmyum install docker-io chkconfig docker onservice docker startdocker version Startup Problems Question

1. Install docker on CentOS 6.4 Docker currently only supports Ubuntu, so it is troublesome to install Docker on CentOS (Issue #172 ). According to the official docker documentation, at least 3.8 of Linux kernel is required, and CentOS 6.4 is the 2.6 kernel. Therefore, I have compiled and installed the latest kernel 3.11.6. After the restart, docker still fails to run, the final reason was found because the aufs module was not integrated during compilation. Aufs needs to be compiled with kernel,

Build your own Docker private repository Service Note:For reference only, this solution may be outdated. docker run-p 5000: 5000 is written on the official docker-registry github. How can I search for images in the private repository service? You can use http: // 192.168.2.45/v1/search to obtain images in a private repository. The introduction of Docker is saved here. Docker's popularity in related fields is no less than that of Tesla in the automobile industry this year. docc.pdf even changed t
