Session
Container Images are foundational to modern infrastructure, yet their internal structure can often be opaque and difficult to debug. Large image sizes, hidden redundant files, and inefficient layering can lead to slower deployments and wasted resources. Manually dissecting layers or understanding disk usage across an image stack is often cumbersome and time-consuming.
This lightning talk introduces skiff, a powerful command-line utility designed to simplify OCI image introspection. Built using podman's container libraries, skiff provides developers and operators with tooling to introspect image layers. We will demonstrate how skiff can be used for the following tasks:
- Identify large layers and files
- Explore layer contents directly
- Diff installed packages
- Locate wasted space
Join this session to learn how skiff can help you analyze, debug, and optimize container images for better performance and resource utilization.
