That's where the image registry comes in. An image registry is a centralized location for storing and sharing your container images. It can be either public or private. Docker Hub is a public registry that anyone can use and is the default registry....
A Docker container is a running instance of a Docker image. However, unlike in traditional virtualization with a type 1 or type 2 hypervisor, a Docker container runs on the kernel of the host operating system. Within a Docker image there is no separate operating system, as illustrated in Fig...

Docker containers provide immutable infrastructure for application packaging and deployment. Containerization improves agility, scalability, and efficient utilization of resources.
Kubernetes vs. Docker Docker technology is used to create and run containers. Docker is made up of the client CLI tool and the container runtime. The CLI tool executes instructions to the Docker runtime, while the Docker runtimes create containers and run them on the OS. Docker also contains...
