What can a docker container do? Container technology is a way to realize operating system virtualization, which allows users to run applications and their dependencies in the process of resource isolation.

There are many things we can do with the docker container, such as the following:

1. The people who write the front end and the technical development who write the back end, or the people responsible for different modules are configured in different environments, so they conflict with each other and fail to run normally. Docker can solve this problem very well.

2. After months of painstaking research and development, it is very troublesome to build a demonstration environment when I want to demonstrate to my customers. At this time, I can provide the Docker image directly to them.

3. When multiple applications share a server, you need to restart the server after modifying a certain system parameter, and other businesses may also be affected. If you are using Docker, you only need to restart the container with the modified parameters.

4. At present, most CVM providers fully support Docker. If your development test is local and the official business is on the cloud, you need to configure a running environment on the CVM and you can use Docker at this time.

Generally speaking, we can create different virtual machines on the server and place different applications on different virtual machines, but the virtual machine overhead is relatively high. Docker can realize the function of isolating the application environment by virtual machines, and the overhead is less than that of virtual machines.

In addition, with the docker container, you can directly encapsulate and transfer the development environment to the operation and maintenance staff, who can directly deploy the docker you gave him, and the deployment speed is fast.

Container cloud products are implemented by deploying container services on cluster servers through docker technology, with tens of thousands of Linux images, powerful, easy to use, easy to use as cluster services and free to build VPCs.
