What can Docker be used for?

1. Automated packaging and release of web applications;

2. Automated testing, continuous integration and release;

3. Deployment and deployment in a service-oriented environment Adjust the database or other back-end applications;

4. Recompile or extend the existing OpenShift to build a PaaS environment.

Benefits of Docker

Docker is an open platform for developing, delivering and running applications. Docker enables you to separate applications from infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure the same way you manage your applications. By leveraging Docker's approach to quickly delivering, testing, and deploying code, you can significantly reduce the delay between writing code and running it in production.

1. Deliver your applications quickly and consistently

Docker simplifies the life of development by allowing developers to work in a standardized environment using local containers for the applications or services you provide. cycle.

Containers are great for continuous integration and continuous delivery (CI/CD) workflows, consider the following example scenario:

Your developers write code locally and share it with colleagues using Docker containers their job.

They use Docker to push their applications to test environments and perform automated or manual testing.

When developers find a bug, they can fix it in the development environment and then redeploy it to the test environment for testing and verification.

After testing is complete, pushing the patch to production is as simple as pushing the updated image to production.

2. Responsive deployment and scaling

Docker is a container-based platform that allows highly portable workloads. Docker containers can run on the developer's local machine, on a physical or virtual machine in the data center, on a cloud service, or in a hybrid environment.

Docker’s portability and lightweight nature also makes it easy for you to dynamically manage your workload and scale up or tear down applications and services in real time as business needs dictate.

3. Run more workloads on the same hardware

Docker is lightweight and fast. It provides a viable, cost-effective, and efficient alternative to hypervisor-based virtual machines so you can leverage more computing power to achieve your business goals. Docker is ideal for high-density environments as well as small and medium-sized deployments, where you can do more with fewer resources.
