In front of our experimental environment there is only one Docker host, and all the containers are running on this host. However, in a real environment there will be multiple hosts, where containers are started, run, stopped, and destroyed, and related containers communicate with each other over the network, regardless of whether they are located in the same host

that no files are added to the new layer of mirrors at this time, but the mirrored JSON file is updated to obtain this information when the container is launched through this image. CMD ["./run.sh"]: Sets the default execution entry for the mirror, which also does not add any files to the new image, but updates the JSON file for the new image only on the basis of the previous layer of mirrored JSON files.

complete, you can start the Redis container with the following command, remember to bring the "-D" parameter:$ docker Run--name myredis-itsmine-d RedisThe function of the "-D" parameter is to let Redis run in the background, because this is the appropriate way to run the background in this case, so here we write this parameter. If you do not have the "-D" parameter, it will be troublesome to deal with, in

Simply put: By using Nsenter, you can go into an already existing container, although this container does not run SSH or any special-purpose daemons. Where do I get the nsenter?

Docker provides a method for direct access to multiple containers, the simplest way is to specify the mapped port directly using the port mapping -p parameter or -P to map all the ports, and multiple containers are accessed directly over the network port. However, network port mapping is not the only way to connect multiple containers in Docker, and you can use D

Using the Docker process, we need to look at the data generated in the container, and between the container and the container, the container and the host before the data sharing, backup and other operations, where the data managem
