Docker Image:A docker image is a read-only template, for example, an image can contain the Ubuntu operating system environment, which installs Apache or other applications that the user needs.Mirroring can be used to create Docker containers. Docker provides a simple mechanism to create a mirror or update an existing i

The Docker container starts a single process at startup, such as an ssh or apache daemon service. But we often need to enable multiple services on one mach
Basic concepts:
Container
Container. Each container can be viewed as a standalone host. The creation of container usually has an image as its template. Analogy to a virtual machine can be understood as image is the mirror of the virtual machine, and container is a running virtual machine. A virtual machine image can create multiple running virtual hosts and be independent of each other. Note: Once created, container will persist if not removed with the RM command. So remember to de

This article describes the use of Docker-machine to build a Docker swarm cluster; Docker swarm is the official Docker-built container cluster orchestration tool, and container orchestration allows you to use a cluster like a machine, The container you are running may run on any node in the container;First, steal a
When you create a Docker container, you should have a new namespace (if you have a separate network), you can see the namespace through the IP netns command, but you can't actually see it.After checking the data, we found that IP netns can only view the network namespace below/var/run/netns. Unlike OpenStack Neutron, Docker automatically creates namespace names in this file and needs to be created manually.

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
