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

The ultimate evolution of DockerGuideIn the past six months, many changes have taken place around Docker security, storage, and orchestration. These changes make it easier for users to use Docker, and also cause a huge earthquake in the entire container ecosystem.
With the security, storage, and orchestration of containers, the entire ecosystem has undergone rapid changes over the past few months. What you

Brief introduction:Docker can run a configured server on a single command, which is handy.But there is also a problem is that when the parameters are more, the mapping directory is more, map port more ...I used to write a script, start with a foot, very low ah.Also see some of the Docker Image introduction page has introduced Docker-compose, but because has been a small application, also did not seriously l
five minutes to meet DockerWhat is Docker?Think of him as an ultra-lightweight virtual machine that is implemented in a novel way, which is probably the right thing to do. Of course, in the implementation of the principle and application is still a huge difference with the VM, and the professional term is the application container (application Container).Why use Docker?So what does the application container
The 1.docker is a very lightweight application container engine, and for better management and use of Docker, the use of web visual management tools seems to be more in line with the needs of most people. Here, I share with you some of the Web tools that I've used: Docker UI, Shipyard, PortainerBecause the fear of their own academic not fine misleading beginners,
In the traditional model, the development team completes the software development in the development environment, does the unit test itself, passes the test, ᨀ to the Code version Management library. Operation of the application deployment to the test environment, QA testing, no problem, notify the deployment of the release to the production environment. The above process involves at least three environments: development, testing, and production. The reality is that the development of self-test

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
enough to become a substitute for the complete server virtualization solution-at least for the moment.
This is because the virtualization field is filled with a large number of extremely complex management infrastructure, designed to help users save, log on and run virtual machine systems, in addition, migration between different hosts, creation of high-availability clusters, and other similar tasks. Solutions represented by VMware vCenter, Microsoft's System Center Virtual Machine manager, and
