# Pentesting Docker Registry (port 5000)
## When to Use
- Default port `5000/tcp`, served over **HTTP or HTTPS** (must determine which first). May sit behind an HTTP proxy where nmap misses it.
- When `nmap` shows `5000/tcp open http Docker Registry (API: 2.0)`, or `/v2/` returns `{}`.
- A registry stores named, tagged images organized into repositories; access lets you pull images (and any secrets baked into layers) or push backdoored images consumed downstream.
## Quick Enumeration
```bash
# Fingerprints:
# GET / -> empty response
# GET /v2/ -> {}
# GET /v2/_catalog -> repo list or UNAUTHORIZED error
