What is a Docker worker?

Docker Workers are processes or containers that perform specific tasks, often as part of a larger distributed system or workflow. In the context of Docker, a worker typically refers to a container running a workload, such as background processing, data analysis, or handling jobs from a task queue. Docker Workers allow organizations to scale tasks horizontally, making it easier to distribute workloads across multiple machines or environments. They are commonly used in continuous integration (CI) pipelines, microservices architectures, and distributed computing environments.
