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 host's kernel). The great value of being cont

Now that Docker is one of the hottest projects on earth, it means that people actually like it more than that.Having said that, I like to use containers, service discovery, and all the new interesting ideas and fields that have been created to switch work as an example.In this article I'll briefly describe using the Docker-py module in Python to manipulate the

Using the Docker process, we need to look at the data generated in the container, and between the container and the container, the container and the host before the data sharing, backup and other operations, where the data management of the container. The management of data currently provides the following two ways:#数据卷 Data Volumes#数据卷容器 Data Volumes containers One, data volumeA data volume, in a way that

Basic concepts of Docker mirrors, containers, and warehouses Mirror A 1.Docker mirror is a read-only template. For example, a mirror can contain a complete CentOS operating system environment in which only httpd or other applications required by the user are installed. 2. Mirroring can be used to create Docker

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 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 Docker, which is quite clea
