What is Docker? Simply put, Docker is a "container" for programs written by the Go language (Linux containers, LXCS); At present, the cornerstone of cloud services is operating system-level isolation, virtual multiple hosts on the same physical server. Docker implements an application-level isolation; It changes our basic development, Operation unit, by direct O

Application background:Docker is the first to run on Ubuntu and Debian, using AUFS memory. Because Docker is becoming more popular, many companies want to use it on Rhel, but the upstream kernel does not include AUFS, so Rhel cannot use Aufs.Eventually, developers developed a new back-end storage engine Devicemapper, based on existing device mapper technology, and made Docker

To see the read-write layer, the role of this layer is very large, docker of the mirror layer and the top two add up, the process within the Docker container only write permission to the read-write layer, the other layer for the process is read-only ( Read-Only ). such as Aufs and other file systems, w

First, what is Dokcer?Docker is an open source project that was born in early 2013 and was originally an amateur project within the DotCloud company. It is based on Google's launch of the Go language implementation. The project later joined the Linux Foundation and complied with the Apache 2.0 protocol, and the project code was maintained on GitHub.Docker has been widely watched and discussed since the open source, so that DotCloud company later chang

that can be compiled and executed. In order for these code to execute smoothly, the development team also has to prepare a complete deployment file to allow the transport team to deploy the application, but even so, there is still a lot of deployment failure. Sun Hongliang said that Docker through the image file, the operating system core, operating the application needs of the system environment, from the bottom of the packaging, to achieve the seam

It stores the mirrored directory as a/data directory, bound to the/docker-registry/data of the host.Then, the Nginx container will also be created, Nginx container through the-link parameters, and registry container connection, so that the Nginx container will know how to communicate with the registry container (in fact, the registry container IP will be bound to the Nginx container of/E Tc/hosts file).4 Starting th

This ensures that the running environment of the current application is independent and that containers are independent of each other. A product from development to launch, from the operating system, to the running environment, and then to the application configuration. As develope

Docker Introduction Docker is an open source application container engine that allows developers to package their apps and dependencies into a portable container, and then publish it to any popular Linux machine or virtualization. Containers are completely using the sandbox mechanism, and there will be no interface between each other. Profile Docker to give a
