About Docker
Docker refers to containerized technology, which is used to support the creation and experimentation of Linux Container. With Docker, you can use containers as lightweight, modular virtual machines, and you get a high degree of flexibility to efficiently create, deploy, and replicate containers, and migrate them from one environment to another.
Docker technology has been on fire a few years ago, and with the popularity of this year's devops, this technology has been sought after by the technology community. The mention of Docker is easily assumed to be a technology under the Linux platform. NET technology doesn't seem to matter to him, but it's a non-. NET core technology, and since the new push of. NET core technology can support the platform, th

Four Docker containers and four docker containersAfter using Docker to create a container, you are concerned about how to enter the container. In fact, there are several ways to enter the Docker container, here we will talk about several common methods to enter the Docker co
Some Questions about learning
How do I heat update mirrors (images)? (You can quickly start or destroy the container.) This time is almost real-time.
How to hot update the game suit?
The advantage is that the environment of each application is independent of each other, even if a container crashes will not affect other containers;
How do you maintain each container using ports? (Method 1 is written in dockerfile, not flexible; Method 2 is specified at run time);
That way, ther
port 80 on the respective container.
User namespaces
Starting with Linux 2.6.23 completed on Linux 3.8)
User and group ID spaces
The user and group IDs of the processes in user namespace can be different from the host, and each container can have a different user and group ID, and a non-privileged user on a host can be a privileged user in the user namespace ;
The concept of Linux namespace is simple, simple and complex. Simply put, we just need to know tha

BackgroundAgile development has been popular for a long time, and now more and more enterprises are beginning to practice agile development advocated by people-centric, iterative, progressive development concept. The first goal of introducing Docker technology in this scenario is to use the virtualization provided by Docker to create a reusable development environment for the development team, allowing t
