SYNOPSIS

docker image command [options]

docker image manages Docker images, which are read-only templates used to create containers. Images contain the application code, runtime, libraries, environment variables, and configuration files needed to run software in an isolated environment.Docker images are built in layers, with each instruction in a Dockerfile creating a new layer. This layering system enables efficient storage through layer sharing between images and faster builds through caching. Images are identified by repository name, optional tag (defaulting to "latest"), and a unique SHA256 digest.The docker image command group provides comprehensive image lifecycle management, from pulling images from registries, building custom images via Dockerfile, tagging for organization, to cleaning up unused images that consume disk space.
