What is Docker?

Docker - Testing and Deployment

Summary

• Docker is a computer program that performs operating-system-level virtualization, also known as containerization.

• A container is a standardized unit of fully packaged software used for local development, shipping code, and deploying system.

• Though Docker presents on how to deal with each of the individual microservices, we also need an orchestrator to handle the whole cluster of services. For that, Kubernetes is the open-source winner, and it has excellent support from the leading cloud vendors.
