, when you only need to use a small amount of resources, is it necessary to virtualize a whole machine?Google has long encountered this problem: we need to release software faster and cheaper, and the computing resources required to support service operation have never been larger, how can this problem be solved? To meet this requirement, we need to abstract existing resources at a higher level so that the service can control resources at a finer gran
billed in at least 10 minutes (or, for an entire hour). ), if you run only a single test program, you may not be consuming as many resources as you test. However, if you run thousands of test-driven programs every day, the cost of resources can go up in a straight line. If you use containers to do the same test work, you only need to use the same resource consumption (the same resource consumption as using a single virtual machine) to complete the thousands of tests, which will greatly save you
technology developed by the company to run cloud services on thousands of servers. It is written in the Go language. The Go language is a static programming language developed by Google based on C language and with loose syntax. After six to nine months of rapid development, the company hired a new CEO, joined the Linux Foundation, and changed the company name to Docker, it also announced that it would focus on the development of Docker containers and their ecosystems.

Each partition is called a security context, in which the virtual system is called a virtual private ser

Objective
In the era of mobile Internet, new technologies need to support the environment, new software delivery process and it architecture, so as to realize the platform of architecture, delivery continuity and business service. Containers will become standard deliverables for next-generation applications, and the container
advantage of a container is that you do not need to tell it in advance how many objects you want to store, as long as you create a container object and call the methods it provides reasonably, all the processing details will be completed by the container itself. It can apply for or release the memory for you and use the best algorithm to execute your commands.

network stack with another container.user-defined NetworkIn this mode, users can use Docker network driver or external network driver plugin to create a custom network. Users can connect multiple containers to the same network. Once a container is connected to a user-defined network, the container can use another container's IP address or name to communicate with each other. This feature requires a version
mirror image in a dockerfile file, typically based on a system-type image, then describe what software to install, what configuration to do, what ports to advertise, and so on, and execute the Docker build command to generate this image. You can publish your own images in a public or private mirrored warehouse.

The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansi

Fundamentally, almost all of the major software, even open-source software, was designed before the advent of mirror-based container technology. This means that putting the software in a container is equivalent to a platform migration. This also means that some pr

"Docker" should be one of the hottest technologies of the 2014, if you haven't heard of it, then you're out, and 2015 will start a new leap. The goal of the Docker project is to implement lightweight operating system virtualization solutions. Docker is based on the Linux
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 Docker build, and then containerized testing, deployment, and operations are all tied to the Docker container. It must be sa
A container holds a collection of objects of a particular type.The standard library vector type is a sequential container. It aggregates a single type element called a container, and then stores and accesses the elements based on their location, which is the sequential container. The order of the elements in a sequenti

Because of its performance, block storage is typically used for database applications. Block storage is also commonly used to provide snapshot functionality, which allows volume to be rolled back to a specific point in time without having to restore the backup.
For containers, block storage is sometimes implemented in the form of container-defined storage. A

that era, a big guy in the industry, Martin Fowler, a leading software leader, proposed the concept of Di (Dependency injection, Dependency injection) instead of IOC.The concept of dependency injection and the concept of inversion of control are essentially the same, but they are described from different sides. The concept of dependency injection describes the dependency of the calling class on an interface implementation class with a third-party
