Question

What can you use Docker for?

Answer 1

• Docker simplifies the development process by allowing developers to operate in structured environments and using local containers to deliver the software and services. CI/CD workflows benefit greatly from containers. Take the following scenario as an example: A group of programmers run programs locally and use Docker containers to share the programs with their colleagues. They use Docker to deploy their applications and run automated and manual tests in a test environment. Also, the programmers fix bugs in the development environment before deploying the programs to the test environment for further testing or validation. When the testing is done, it's only a matter of pushing the modified Image to the manufacturing environment to bring the patch to the consumer.
• The container-based Docker framework enables highly portable workflows. Docker containers can run on a desktop, data center, cloud, or hybrid environment.
• Because of Docker's portability and lightweight design, it can handle workloads dynamically and scale them up or down in real-time.
• It provides a better, cost-effective solution to hypervisor-based VMs, allowing you to make better use of your computing resources. Docker is ideal for high-density environments as well as medium and small deployments where limited resources are available.
