What can you do with Docker
Today, I will talk to you about what you can do with Docker. Many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.
Docker is a similar idea. Cloud computing is popular now, and cloud computing is like a freighter. Docker is the container.
1. Different applications may have different application environments. For example, websites developed by. Net and php depend on different software. if the software they rely on is installed on the same server, it will take a long time to debug, and it will be troublesome and cause some conflicts. For example, IIS and Apache access ports conflict. At this point, you need to isolate websites developed by. Net and websites developed by php. 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 from the virtual machine, and the overhead is less than the virtual machine, which means saving money.
two。 When you develop software, you use Ubuntu, but OPS manages centos. OPS will encounter some Ubuntu-to-centos problems when transferring your software from development environment to production environment, such as: there is a special version of the database, which is supported only by Ubuntu, but not by centos. In the process of transfer, OPS has to find a way to solve this problem. At this time, if you have docker, you can directly package and transfer the development environment to the operation and maintenance staff, and the operation and maintenance staff can directly deploy the docker you gave him. And the deployment is fast.
3. In terms of server load, if you open a separate virtual machine, then the virtual machine takes up free memory, which will be used when deployed by docker.
After reading the above, do you have any further understanding of what you can do with Docker? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
