If the virtual machine is simulated running a full set of operating systems (providing a running state environment and other system environments) and running on the appli

Objective Today, in the Docker, we are able to easily package our applications with containers and deploy them on our servers and run them. However, talking about how to stop the Docker container in the running and terminate the program correctly is a very worthwhile topic to discuss. In fact, in our daily projects, this is a problem that we often have to confr

in our when Docker container operation, sometimes misoperation or other reasons inadvertently quit the container in operation, you may worry that some of your operations have not been saved, there is no need to worry, this article will provide a variety of methods for your reference (my recommendation to use the last one).

If you want to do data persistence, Docker provides data volume or data container

Docker data volumes and data containers These two days began to learn Docker, found that Docker is really strong, so that the site deployment and maintenance efficiency greatly improved. So ready to be on hand to maintain a few station, all Docker. It is felt in the process of finishing that

In real life, a container is a thing to hold something. Put your application in the container, the environment in the container you can freely customize, you can install anything you need in the configuration application, and then you can take the container of the application and run it anywhere, where you don't need t

Docker is an open-source tool that allows users to conveniently deploy Linux iner containers. Docker quickly became an unofficial standard for the iner technology, so it was

Jérôme Petazzoni (Docker evangelist) Translator: Mark Shao (senior engineer, EMC China) If you use Docker on CentOS, Rehl, Fedor, or other Linux distributions that do not have AUFS support by default, you may need to use Device Mapper's storage plug-in. By setting this plugin as the default, it will store all your containers in a short 100G file and limit the maximum of 10GB per
