Description: Image cleanup in the context of containerization refers to the process of removing unused or dangling images to free up disk space. As containers are created and used, multiple images can accumulate over time, taking up valuable space on the system. This process is crucial for maintaining an efficient development or production environment, as unused images can consume unnecessary resources and slow down system performance. Image cleanup can be performed using specific container management commands, such as ‘docker image prune’, which allows for the removal of images that are not associated with any running containers. Additionally, options can be specified to remove images that have not been used for a certain period. Proper management of images not only optimizes disk space usage but also facilitates the organization and maintenance of the container environment, ensuring that only necessary images are available for use. In summary, image cleanup is an essential practice in container management that contributes to the efficiency and effectiveness of container handling.
