Docker Host Maintenance
Docker does not remove unused Docker objects, such as images, containers, volumes, and networks. Piling up such objects may quickly fill up the storage space. It is essential to eliminate such dangling objects (often called garbage collection) to maintain the resources and health of the Docker host.
Docker provides the prune command option to clean up unused docker objects. For more information about Docker Official, refer to https://docs.docker.com/config/pruning/
With docker unused objects, QCSA residues is stored in Docker Host's shared or common directory. QCSA objects such as installed rpms and temporary scan data is stored.
Monitor the storage, arrange a quick downtime, and clean QCSA residues when needed.
