In the process of introducing Docker technology, the first thing that the development team needs to solve is to let team members master the use of Docker command line as soon as possible. After familiar with the Docker command line, the team needs to address several key issues as follows:1) Base i

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.

By default, the Docker daemon generates a socket (/var/run/docker.sock) file for local process communication without listening to any ports, so you can only use the Docker client locally or use the Docker API to do the operation.If you want to operate the Docker host on another host, you need to have the
