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.

is so large is that many companies are using Docker at an alarming rate. At this July's Open source Conference (OSCon), I encountered countless businesses that had already moved server applications from virtual machines (VMS) to containers. Indeed, James Turnbull, vice president of Docker's executive services and support, told me at the meeting that three of the big banks have been using Docker's beta version and are now using

A Docker image is a read-only template.For example, an image can contain a complete CentOS operating system environment where only httpd or other applications are installed.

The above process involves at least three environments: development, testing, and

ObjectiveIn a previous blog, "Setting up a Docker registry private warehouse in Ubuntu" introduces a simple way to build a Docker private repository. But it was used to modify the "--insecure-registry" parameters, which is used in the local area network, but also reluctantly suitable. But if you want to build a private warehouse server for a production environmen

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 support pluggable, and now ther

different in kernel use. Each virtual machine uses one kernel. The Docker container shares the kernel among all containers. The shared kernel brings some efficiencies, but at the expense of high availability and redundancy. If the virtual machine has a kernel crash, only the virtual opportunity on this kernel is affected. And the Docker container if the kernel crashes, all containers will be affected.
