Answer
Docker deletes metadata so deleted container IDs cannot be reused.
Quick Answer
When you docker rm a container, Docker removes the container metadata and its writable layer. The container ID is freed. If a restart policy was set, the container is no longer tracked — it won't restart. The OCI state directory is cleaned up, and containerd removes the container record from its internal database.
