docker

Docker is an open-source software product for Linux that builds and runs container images. It is intended for Linux users who need to create or execute software environments packaged as container images. Its core purpose is to provide these build and runtime operations within a Linux-based workflow.

The product supports building container images from the relevant source and running those images on a Linux system. Building is useful when users need to produce an image, while running is used when an existing image needs to be executed. These capabilities define Docker’s role as a tool for working with container images rather than as a general-purpose application.

MirrorNest places Docker in its Networking category because container-based software is commonly used in networked computing environments. Its listed platform is Linux, so the catalog entry is intended for users seeking the Linux version. The open-source license also allows the product to be used within the terms of its source distribution.

MirrorNest mirrors the official build directly onto its own storage before making it available through the catalog. Each mirrored file is scanned for malware before publishing. The software is built by Canonical from source code published by Docker, Inc., while the mirrored catalog copy is distributed by MirrorNest.
