Use a lightweight and flexible VM of the Docker container to take over the dependency on hell. Learn how Docker is based on LXC technology to make apps portable and independent by packaging applications in containers. Imagine that you can easily package the application and its dependencies, and then test the labels in other development and testing scenarios:

Docker is an open-source engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Developers who compile tests on notebooks can be deployed in batches in a production environment, including VMS (virtual machines), bare metal, OpenStack clusters, and other underlying application platforms.Docker is typically used for the following scenarios:Automated packagi

Alpine Linux's official website:http://www.alpinelinux.org/#官方Https://pkgs.alpinelinux.org/packages #官方提供的安装包查询When you use Docker to create a container, the underlying image typically chooses Ubuntu or CentOS, regardless of the size of the image above 100MB.Alpine Linux is a security-oriented, lightweight Linux distribution.Alpine Linux employs musl libc and busybox to reduce the volume and runtime resourc

The container is the second core concept of Docker, and the simple one is that the container is a running instance of the mirror, and the difference is that it has an extra writable file layer. If the virtual machine is simulated running a full set of operating systems (providing a running state environment and other system environments) and running on the appli

Dockerfileis the raw material of the software, Docker镜像 is the delivery of the software, but it Docker容器 can be considered as the operating state of the software. From the perspective of application software, Dockerfile, Docker images and Docker containers represent three different stages of the software, Dockerfile de

Docker image, container, warehouse concept Docker mirroring Docker mirroring (image) is similar to a virtual machine image, and can be interpreted as a read-only template for the Docker engine, including a file system. For example, a mirror can fully contain the Ubuntu op

This is a creation in Article, where the information may have evolved or changed. Before Docker 1.9 was born, there were roughly three container communication scenarios across multiple hosts, such as: 1. Port mapping The port P of host A is mapped to Port P ', which is the network space listener of container C, and is only available for applications and services

Docker data volumes and data containers These two days began to learn Docker, found that Docker is really strong, so that the site deployment and maintenance efficiency greatly improved. So ready to be on hand to maintain a few station, all Docker. It is felt in the process of finishing that

Looking at the history of Docker, you'll find that Docker has been emphasizing the word "application", and Docker wants to provide containerized solutions for distributed applications.From the life cycle of the Docker application software, the development work appears to be before the

This is a creation in Article, where the information may have evolved or changed. The research on the container network has been interrupted for some time due to the reasons for the exchange of work in 2016. With the current project to kubernetes application in depth, I feel that before the shallow understanding of the container network is not enough, the container
