Versions:
Port 2.4.0, authored by Kevin Boss, belongs to the Developer Tools category and serves as a lightweight command-line utility engineered to orchestrate multiple Docker images and their associated tags from a single interface. Released as the sixth iteration in its release history, the software targets developers and DevOps engineers who routinely juggle numerous local container variants during iterative testing, continuous-integration pipelines, or micro-service prototyping. Users can enumerate every downloaded image, inspect available tags, and interactively select which combination should be launched into a container, eliminating the need for lengthy docker pull and docker run sequences. Once a container is active, Port exposes snapshot primitives that capture the running state as a new image layer, enabling instant roll-back or parallel experimentation without jeopardizing the baseline. Image lifecycle operations such as deletion, renaming, or retagging are exposed through sub-commands that respect Docker’s internal dependency graph, thereby preventing accidental removal of still-referenced layers. Because the utility is statically compiled, it adds no runtime footprint to the containers it manages, and its JSON output mode integrates cleanly with shell scripts and CI dashboards. Configuration is minimal: by default Port binds to the local Docker socket, yet it can be pointed to remote daemons through standard environment variables. The tool is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation alongside other applications.
