how to start docker

Before we did the experiment is on a host, in fact, in the real environment there are multiple hosts, containers on these hosts to start, run, stop and destroy, related containers will communicate with each other over the network, whether they are running on the same host.For this kind of song Multi-host environment, how should we manage it efficiently?The first problem is: Install and configure Docker for

: Using a latest mirror at a point in time, the application container is functioning correctly, and then another point in time follows the corresponding dockerfile,build out mirror to run the application container and fails. Cause Analysis: Docker official about the same type of Docker mirror latest label, does not permanently give a specified Docker mirror, but

advantages over traditional virtualization approaches.First, the launch of a Docker container can be implemented in seconds, which is much faster than a traditional virtual machine, and secondly, Docker has a high utilization of system resources and can run thousands of Docker containers simultaneously on a single host.In addition to running applications, the co

this container are completely customized by the assembler. 2. Basic concepts of docker Docker itself is a container running carrier. To run a container, you must correctly understand the concepts of warehousing, image, and container. As described above, the meaning of the image is clear when you deploy a running instance of the container. An image is a packaged and deliverable running environment. when we

a container, packaged containers can be published on any popular Linux machine, the Linux machine in this case is not accurate, thanks to the Docker for Windows project and Hyper-V Development, Dockeryou can also run on a Windows 10 system in a good state, but the author does not recommend it Docker for Windows for production environments.

, that is, after configuring mirror, you can still enter docker pull ubuntu to pull the Docker hub image, in addition to the speed is faster, and no difference before.Docking the Docker hub ecosystem in a more convenient way, using registry mirror naturally became my first choice. Next I'll take a look at Docker's process of using mirror to pull the mirror. In th
