Introduction to Docker creating background项目的开发环境和部署环境不一致，部署环境配置难度大。集群技术的发展，集群的相同配置操作难度大。Basic concept使用Go语言实现的云开源项目，"一次编译，处处运行"，只需要一次配置环境，就可以在其他环境一键部署，软件即容器，虚拟化。Virtualization Technology虚拟机：一种带环境安装的解决方案，模拟整套操作系统，笨重。容器：将所有运行环境打包成互相隔离的容器，不进行硬件虚拟。Development/Operations (DEVOPS)开发自运维、一次开发，处处运维。Official informationDockerDocker ChineseDocker HubEnvironmental Installation System Requirements 1.

treats GID in the same way as the UID. Many students simply understand the Docker container as a lightweight virtual machine, although this simplifies the difficulty of understanding container technology but it also leads to a lot of misunderstandings. In fact, unlike virtual machine technology: All containers running on the same host share the same kernel (the

How to delete docker images/containers Docker images often occupy hard disk space unconsciously. To clear redundant images, you can use the following methods: 1. Enter the root permission Sudo su 2. Stop all container to delete the images: Docker stop $ (

When using Docker, we often encounter the application that I need two or more containers, some of which need to use the services provided by other containers. For example, we need a container to provide MySQL database services, while the other two containers are connected as clients to use the MySQL database service. L

Docker Mirrors: First of all, we know that the operating system is divided into kernel and user space, compared to Linux, the kernel boot, will mount the root file system to provide user space support. and Docker mirror image, it is equivalent to a root file system, but this file system is a little special, provide the container runtime needs of the program, libr

Let's start with today's two main characters: NFS and DockerWhat is NFS?The NFS (Network File system), which is one of the file systems supported by FreeBSD, allows computers in the network to share resources across TCP/IP networks. In an NFS application, a local NFS client application can transparently read and write to files located on the remote NFS server, just as you would access a local file. Excerpt from Baidu EncyclopediaWhat is Docker?This is

containers, This is hard to do with traditional virtual machine technology.The main issues that Docker solves(1) environmental dependenceFor example, Java's web development deployment environment needs to specify JDK version, Web server and its version, various jar packages and their versions, etc.Docker is a container that can be put into a specific version of the operating system, then install

For friends who know about the Docker container network, I think the network of virtual machines is not unfamiliar, after all, we are the people who follow this era to learn and progress together. Compared to Vm,docker's network is gradually maturing, this article mainly for the Macvlan to do a simple introduction.Why Macvlan?First we compare the VMS and the different networks in

The three main advantages of Docker containers are: First: A constant feature – operating system, library version, configuration, folders, and applications are all covered. You can introduce the test images used in the quality inspection process to the production environment intact. Second: lightweight – The container is very small in size. Compared

In the previous articles, we discussed how to install Docker in Ubuntu14.04 (64-bit) and how to deploy an Apache server in Docker and access the server on an external computer, and deploy in Docker A MySQL database and access the database on an external computer. The following is a discussion of the Docker between the

web. The general process should be consistent with the following: (The following is just a guess, because the author does not have much time to study its source code)1. Create a net Namespace netns1.2, create a pair of Veth, add Peer to netns1, the other end of the connection to the bridge BRIDGE0.3. Assign IP to these two veth.4. Use NETNS1 to start the procedure in the container such as/bin/bash.Unfortunately, the Docker run does not have an option

Docker creates containers and mirrors that support SSH services Use CentOS as a container here, so first download CentOS images Sudo docker pull CentOS Download and run a CentOS container, Here I use CENTOS6 as my Test Container Sudo docker run--name=centos-ssh-i-T centos:centos6/bin/bash
