Versions:
dget is a lightweight command-line utility created by developer 刘铭 that enables direct downloading of container images from Docker Hub without requiring the full Docker engine to be installed. Released in a single build dated 2024.07.13.1, the tool is positioned within the developer-tools/system-utilities category and addresses situations where bandwidth is limited, Docker daemon startup is restricted, or only specific image layers are needed for offline analysis. Typical use cases include CI pipelines that must cache base images before runtime, security researchers who need to fetch and inspect individual layers, and Windows or Linux administrators who want to distribute container payloads across air-gapped networks through scripts. By parsing Docker Hub registry endpoints, dget reconstructs the requested image tarball locally, exposing the same checksums published by upstream maintainers so integrity can be verified without registry write access. The binary is distributed as a portable executable with no external dependencies, making it suitable for ephemeral build agents, minimal containers, or rescue environments where package managers are unavailable. Although the project remains at version 1, its date-stamped release cadence allows users to track incremental improvements such as enhanced retry logic, concurrent layer fetching, and automatic platform selection that matches the host architecture. All functionality is triggered through straightforward arguments, eliminating the learning curve associated with heavyweight registry clients while still respecting Docker Hub rate limits and authentication scopes. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
