# API Reference: Distroless Container Image Analysis Agent
|
|
|
|
## Dependencies
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| trivy CLI | >=0.50 | Container vulnerability scanning (subprocess) |
|
|
| docker CLI | >=24.0 | Image inspection and property checks (subprocess) |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python scripts/agent.py \
|
|
--images gcr.io/distroless/static-debian12 python:3.12-slim \
|
|
--compare python:3.12 gcr.io/distroless/python3-debian12 \
|
|
--output-dir /reports/
|
|
```
|
|
|
|
## Functions
|
|
|
|
### `run_trivy_scan(image) -> dict`
|
|
Runs `trivy image --format json --severity CRITICAL,HIGH,MEDIUM`.
|
|
|
|
### `get_image_size(image) -> int`
|
|
Runs `docker inspect --format {{.Size}}` for byte count.
|
|
|
|
### `count_vulns_by_severity(scan_data) -> dict`
|
|
Parses Trivy JSON Results for CRITICAL/HIGH/MEDIUM/LOW counts.
|
|
|
|
### `compare_images(base_image, distroless_image) -> dict`
|
|
Scans both images, computes size and vulnerability reduction percentages.
|
|
|
|
### `check_distroless_properties(image) -> dict`
|
|
Tests for shell access and package manager presence via `docker run`.
|
|
|
|
### `generate_report(images, distroless_pairs) -> dict`
|
|
Full analysis with individual scans, comparisons, and summary.
|
|
|
|
## Distroless Properties Checked
|
|
|
|
| Property | Check Method |
|
|
|----------|-------------|
|
|
| Shell access | `docker run --entrypoint "" image sh -c "echo"` |
|
|
| Package manager | `docker run --entrypoint "" image which apt/apk/yum` |
|
|
|
|
## Output Schema
|
|
|
|
```json
|
|
{
|
|
"summary": {"images_scanned": 4, "minimal_images": 2},
|
|
"comparisons": [{"size_reduction_pct": 82.3, "vuln_reduction_pct": 95.0}],
|
|
"image_scans": [{"image": "gcr.io/distroless/static", "is_minimal": true}]
