About:
Dive is a command-line interface (CLI) tool designed to analyze Docker images, focusing on their layered structure. It provides a detailed breakdown of each layer within an image, allowing users to understand file changes, sizes, and permissions. The tool's primary value is in optimizing image builds by identifying inefficiencies and unnecessary files.

Key Features:

Interactive UI for exploring image layers
Efficiency calculation to detect wasted space
CI integration for build validation
File tree view for each layer

Use Cases:

Optimizing Dockerfile instructions to reduce image size
Auditing third-party images for security risks or bloat
Educating developers on how Docker layering works

Alternatives:

docker history – Native Docker command providing basic layer info, but lacks interactive exploration and efficiency metrics.
docker-slim – Focuses on automatically minifying images rather than detailed analysis of existing layers.
