Docker application scenarios
-
Automated packaging and publishing of web applications.
-
Automated testing and continuous integration, release.
-
Deploy and tune databases or other background applications in a service-based environment.
- Build your own PaaS environment by compiling or extending an existing OpenShift or Cloud Foundry platform from scratch.
Advantages of Docker
-
1. Simplify the process:
Docker allows developers to package their applications and dependencies into a portable container, and then publish it to any popular Linux machine, enabling virtualization. Docker has changed the way of virtualization, allowing developers to put their work directly into Docker for management. Convenience is already the biggest advantage of Docker. In the past, tasks that took days or even weeks can be completed in seconds under the processing of Docker containers. -
2. Avoid choice phobia:
If you have choice phobia, it is still a senior patient. Docker helps you pack your tangle! For example, Docker images; Docker images contain the runtime environment and configuration, so Docker can simplify the deployment of multiple application instances. For example, web applications, background applications, database applications, big data applications such as Hadoop clusters, message queues, etc. can be packaged into an image deployment. -
3. Cost savings:
On the one hand, with the advent of the cloud computing era, developers do not have to configure expensive hardware in pursuit of results. Docker has changed the mindset that high performance must be expensive. The combination of Docker and the cloud makes the cloud space more fully utilized. It not only solves the problem of hardware management, but also changes the way of virtualization.
