Foreword Docker is a container engine project based on lightweight virtualization technology Docker.inc Company Open Source, the entire project is based on go language development and complies with the Apache 2.0 protocol. With tiered mirroring standardization and kernel virtualization technology, Docker enables application developers and operational engineers to publish applications across platforms in a unified manner, and to provide resource-isolated applications running environments with little overhead. Due to many novel features and the openness of the project itself, Docker in less than two years to quickly obtain a lot of I. ...

Editor's note: With Docker, we can deploy Web applications more easily without having to worry about project dependencies, environment variables, and configuration issues, Docker can quickly and efficiently handle all of this. This is also the main purpose of this tutorial. Here's the author: first we'll learn to run a Python Dewar application using the Docker container, and then step through a cooler development process that covers the continuous integration and release of applications. The process completes the application code on the local functional branch. In the Gith ...

OpenStack was rated as the most popular Open-source project for the cloud, followed by Docker and KVM. It is noteworthy that OpenVZ and other container technology existed very early, even more mature than Docker, why Docker development so fast? A Linux capacity ...

Compared with Vm,docker, it has obvious advantages in light weight, configuration complexity and resource utilization. With the maturing of Docker technology, more and more enterprises begin to consider improving their IT system through Docker. This article enumerates some Docker practical application scenes, in order to be able to play the role of the trigger, to help us to use Docker more conveniently.

The Docker has been in use for more than a year and has been installed on both local Linux systems and cloud platforms. At that time learned a lot about managing mirroring, the flexibility to create mirrors for any platform, learn to write some of your own programs that are not relevant to Docker. I've tried to summarize my experience to the following five points, providing references for those who just started using Docker. When making a mirror you need to be particularly clear I try to run my application without the root user. Most Linux distributions have one advantage: when you install a service, the operating system ...
