Container — Container Technology Reference
Quick-reference skill for container internals, image formats, and runtime mechanics.
When to Use
- Understanding how containers provide process isolation
- Debugging container networking, storage, or resource issues
- Learning OCI image specification and layer mechanics
- Comparing container runtimes (runc, containerd, CRI-O)
- Optimizing Dockerfile builds for smaller, faster images
Commands
intro
