Learn some of the latest trends Docker is a new and good thing.1 About DockerDocker provides an envelope (envelope), or container, that can run your application. It was originally an amateur project launched by DotCloud, and was open source in the early days. It attracts a lot of attention and discussion, causing DotCloud to rename it to Docker Inc. It was originally written in the Go language, which is equivalent to a pipeline added to the LXC (LinuX

Learn about Docker from today, and record it through the collection and learning of online materials. What is it?Docker is a VMS-like, ultra-lightweight virtual machine based on the LXC implementation.It differs from VMS in that VMS provide a complete operating system virtual environment, from the hardware level, contains a lot of similar hardware drivers, virtual processors, network interfaces and so on not needed information, and the virtual m

Docker is an open source project that was born in early 2013 and was originally an amateur project within the DotCloud company. It is based on Google's launch of the Go language implementation. The project later joined the Linux Foundation and complied with the Apache 2.0 protocol, and the project code was maintained on GitHub.Docker has been widely watched and discussed since open source, so that DotCloud company later changed its name to Docker INC. Redhat has focused on supporting Docker;goog

Server virtualization refers to the operating system and hardware to add a layer, called the hypervisor layer, the next control hardware, on the host operating system, operating system OS in file form, known as virtual machine, the main problem is the hardware utilization and flexibility of the problem, the common solution for VMware Vsphere,xen,kvm,hyper-v.. Container virtualization refers to the application of packaging in the OS to run in the form of processes, applications and applications a

Contribute an article:Cloud hosts can select operating system images to quickly create a host, which is more convenient than a virtual machine, and we can do this locally because of the Docker thing. It relies on LXC (Linux Container) to get a configured Linux image from the network, and it is very easy to run its own applications in an isolated system. Also because its underlying core is a LXC, you need to

ObjectiveDocker is designed to provide an automated deployment solution for an application that quickly creates a container (lightweight virtual machine) on a Linux system and deploys and runs the application, making it easy to automate the installation, deployment, and upgrade of applications with configuration files. Because of the use of containers, it can be very convenient to the production environment and development environment, independent of each other, this is the most common Docker pl

Python Socket programming and pythonsocket Programming Socket is the foundation of network applications. Python makes network socket programming very simple. In this introduction, we will create a simple server for receiving requests from the corresponding client program.I am a little obsessed with Linux Containers recently, so we will also implement two Containers on the server. At the same time, we can create other hosts in a few seconds in the container, which can simulate a network very easi

discussion, causing DotCloud to rename it to Docker Inc. It was originally written in the Go language, which is equivalent to a pipeline added to the LXC (LinuX containers,linux container), allowing developers to work at a higher level of concept. Docker extends the Linux container (Linux Containers), or LXC, with a high-level API that provides a lightweight virtual environment for the process alone. Docke

First of all. Because Docker implementations require some Linux components to support itself and kernel features. Make sure that the CentOS version number is greater than 6, and that the kernel version number is greater than 2.6.32-431.
