Docker plays a crucial role in DevOps, especially if you are working on microservices. Docker is used to build containers in CI flow, where you will perform source code analysis, unit test cases on the source code, if it works fine then you will be building and pushing this image to the registry.
In CD, you will deploy this container in Kubernetes and performs some application-level test cases. This you will continue in different stages (For example Development, Staging, Production). Once a container is deployed in production, further you will monitor logs using ELK stack using containers and analyze metrics using GHI stack using Containers. Most of the tools which are used to create a workflow will be running in Docker containers. “So the entire DevOps workflow is Containerized”
