technical bottlenecks in server deployment to fully implement an immutable infrastructure, which makes it difficult to implement in a real-world environment. Some tools such as: Packer can alleviate the difficulty of creating virtual machine images to some extent, but you still need to face a whole set of environment construction work, which usually takes a long time to build and build, because you generally need to download a few g of files to build a separate system.

This menu is from the visual Studio Tools for Docker extension. This step will add basic dockerfile and other docker-compose files. With this out-of-the-box step, I've done all the configuration to

This is why the official installation method for running Docker on non-Linux systems, such as OS X and Windows, is to install Precise64 based on Ubuntu virtual machine with the assistance of Vagrant.

Docker is an open-source engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Developers who compile tests on notebooks can be deployed in batches in a production environment, including VMS (virtual machines), bare metal, OpenStack clusters, and other underlying application platforms.Docker is typically used for the following scenarios:Automated packagi

Each container has its own network device, IP address, IP routing table,/proc/net directory, port number, and so on. This also allows the same application in multiple containers on a host to be bound to port 80 on the respective container.
