In Docker, what does the term 'container orchestration' imply?

Container orchestration refers to the automated coordination and management of multiple containers running across various environments, often spanning multiple hosts. This involves tasks such as deployment, scaling, networking, load balancing, and ensuring that containers are running as expected. Orchestration tools, like Kubernetes and Docker Swarm, provide the frameworks to manage the lifecycle of containers effectively, enabling developers to create resilient applications that can scale according to demand.

In contrast, setting up a single Docker container focuses on the deployment of individual instances rather than the management of a whole ecosystem of containers. Creating Docker images is about building the blueprints for containers but does not involve their operational management. Configuring Docker CLI settings pertains to the command-line interface configuration and does not encompass the broad scope of management and orchestration of multiple containers. Therefore, the emphasis on managing multiple containers across multiple hosts truly captures the essence of container orchestration.
