Explain what are Docker objects and namespaces?
Docker objects: The Docker objects refer to the Docker images, containers and services. A Docker image is a read-only template having the configuration and runtime instructions for Docker instructions. Under the service instruction scaling of the containers across multiple Docker, daemons are allowed. All this together works as Swarm.
Docker namespaces: It refers to a technology that provides individual and isolated workspaces known as containers. Docker namespaces also provide a layer of isolation for containers.
