In this lesson, we'll find out the basics of running Docker containers. We'll go to the download images from Docker Hub, what's happens when you stop containers, how to restart a container on Ce it ' s been stopped, and also how to remove containers.Run a container:Docker run MONGO // run the container, if container not exists, download from hubThis would output the console log in the command lineAnother-

Docker is useless and unnecessary for small and medium-sized enterprises to build Paas. It is a little less useful to use it as a personal sandbox, I personally think that docker can be used as a standard development, testing, and production environment for small and medium-sized enterprises.I drew a simple figure:Docker occupies a small amount of resources. It is more than enough to deploy 100 containers o

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.How do we manage this multi-host environment effectively?The first problem we faced was i

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 all hostsPreviously, we installed a
