Questions tagged [container-image]

Container images are packages used to create Docker containers.

Container images are the basis of Docker or OCI containers. They usually reside in container image registries. When a container is built, the requested base image is downloaded from the corresponding registry if not available already locally.

More information on building container images can be found on the Docker documentation page.
