DockerDocker containers can be run multiple times after a buildDcoker vs. virtual machines: Usually we are running Linux on the system, Linux virtualization on the systems, running various applications in the virtual host, and the virtual machines are completely isolated, while Docker is running Linux on the hardware level and doing Docker on the system. Engine,
inscrutable, and the big-god figures are not necessarily clear.Anyone who has used a virtual machine should know that starting a virtual machine is like starting a computer, the initialization process is quite slow, we need to wait a long time to see the login interface. Once the virtual machine is started, you can establish a network connection with the host to ensure that the virtual machine is connected to the host. Different virtual machines are isolated from each other, that is, they do no

The Docker containers under the same host are mutually connected by default. The IP address can be viewed by Docker inspect ID or name. Ping can be ping in a container that does not pass.
But we found by observation that each boot container's IP address is not fixed, so if we use IP address to achieve interconnection is obviously not reliable. But we found that these IP is in the same network segment and th

Docker Introduction:
Docker is an open source application container engine that allows developers to package their apps and dependencies into a portable container, and then publish it to any popular Linux machine or virtualization. Containers are completely using the sandbox mechanism, and there will be no interface between each other.
