Images & Compose

Images

• Pull with optional registry authentication and per-layer progress.
• Build from a Dockerfile — pick the context, tag, target stage, build args and cache option, and watch the log stream live. You can also drag a Dockerfile onto the window, or use Open With → Gantry.
• Tag and remove images; prune dangling or all unused.
• Inspect an image's layers/history and raw JSON, and see which containers use it.

Compose

On apple/container hosts, open a docker-compose.yml from Docker → Open Compose File…, Finder's Open With, or by dropping it on the window. Choose the host, toggle recreate / no-cache, and bring the project up with a live, colorized log stream. When it's up, Gantry jumps to the host's Containers grouped by the Compose project.
