In front of our lab environment, only one Docker host container is running on this host. However, in a real environment, there will be multiple host containers that start, run, stop, and destroy related containers in these hosts, regardless of whether they are located in the same host.How can we manage such a multi-host environment efficiently?The first problem we faced was installing and configuring Docker
About Docker
Docker refers to containerized technology, which is used to support the creation and experimentation of Linux Container. With Docker, you can use containers as lightweight, modular virtual machines, and you get a high degree of flexibility to efficiently create, deploy, and replicate containers, and migrate them from one environment to another.

Three docker components: Image and docker1. Images of Docker's three major components.
A corresponding image must exist locally before Docker runs the container. If the image does not exist locally, Docker downloads the image from the image repository (default isDocker Hub Public Registry server warehouse ).Obtain images from the repository, manage images on the
take a look at what benefits we get after introducing Docker:
1. ensure the consistency of the running environment. The online environment and the test environment use the same image. After the test environment passes the test, no bugs will occur after the launch due to environment differences.
2. It is convenient and convenient to deploy new projects. Automatic deployment fails because of operating system

When using docker run to create a Docker container, you can use the -- net option to specify the container network mode. Docker has the following four network modes:
· Host mode, specified using -- net = host.
· Container mode, w
