From 742b3abd6f619c4b41215c4402d83efad4dc04ad Mon Sep 17 00:00:00 2001 From: Advait Patel Date: Fri, 12 Jun 2026 03:30:00 -0500 Subject: [PATCH 1/5] feat: add docker compose security scanning and multi-service orchestration ## Summary Adds native support for scanning `docker-compose.yml` files. This feature detects orchestration-level misconfigurations and automatically orchestrates the existing Dockerfile and image scans for every service defined in the compose file. ## Changes - **Compose Parser**: Added `ComposeScanner` using `ruamel.yaml` to parse compose files while preserving accurate line numbers for findings. - **Compose Orchestrator**: Added `ComposeOrchestrator` which extracts all services, identifies their build contexts/images, and runs the existing `DockerSecurityScanner` on each. - **Checks Implemented**: - **CRITICAL**: `compose-docker-socket-mount`, `compose-privileged`, `compose-host-network`, `compose-host-namespace`, `compose-dangerous-capabilities`, `compose-sensitive-host-mount` - **HIGH**: `compose-plaintext-secret-env`, `compose-port-bound-all-interfaces`, `compose-disabled-security-opt`, `compose-no-non-root-user` - **MEDIUM**: `compose-latest-or-untagged-image`, `compose-no-resource-limits`, `compose-env-file-secret-risk`, `compose-writable-root-fs` - **LOW**: `compose-no-new-privileges`, `compose-no-network-segmentation`, `compose-missing-healthcheck` - **Pipeline Integration**: All compose-level findings and per-service findings are merged and passed through the existing LLM remediation layer and scoring system. - **CLI**: Added the `--compose [PATH]` flag. If no path is provided, it auto-detects standard compose filenames in the current directory. - **Docs & Examples**: Updated `README.md`, added `docs/CHANGELOG.md` entries, and added insecure/secure compose examples in the `examples/compose/` directory. ## Testing - Added `tests/test_compose_scanner.py` with full coverage for parser logic, every rule, line mapping, integration, and offline mode. - Existing test suite passes unchanged. --- README.md | 4 + docker-compose.yml | 18 + docksec/cli.py | 105 +++-- docksec/compose_scanner.py | 451 +++++++++++++++++++ docksec/compose_scanner_cli.py | 1 + docs/CHANGELOG.md | 12 +- examples/compose/docker-compose-insecure.yml | 19 + examples/compose/docker-compose-secure.yml | 51 +++ requirements.txt | 3 + setup.py | 1 + test_compose.py | 8 + tests/test_compose_scanner.py | 149 ++++++ 12 files changed, 792 insertions(+), 30 deletions(-) create mode 100644 docker-compose.yml create mode 100644 docksec/compose_scanner.py create mode 100644 docksec/compose_scanner_cli.py create mode 100644 examples/compose/docker-compose-insecure.yml create mode 100644 examples/compose/docker-compose-secure.yml create mode 100644 test_compose.py create mode 100644 tests/test_compose_scanner.py diff --git a/README.md b/README.md index 9cecad7..8f02560 100644 --- a/README.md +++ b/README.md @@ -94,6 +94,9 @@ docksec Dockerfile # Scan Dockerfile + Docker image docksec Dockerfile -i myapp:latest +# Scan a Docker Compose file and all its services +docksec --compose docker-compose.yml + # Scan only a Docker image docksec --image-only -i myapp:latest @@ -107,6 +110,7 @@ docksec Dockerfile --scan-only - **Smart Analysis**: AI explains what vulnerabilities mean for *your* specific setup. - **Multi-LLM Support**: Use OpenAI, Anthropic Claude (4.x), Google Gemini (1.5+), or local models via Ollama. +- **Docker Compose Scanning**: Detect orchestration-level misconfigurations and scan all services in a compose file. - **Deep Integration**: Combines Trivy (vulnerabilities), Hadolint (linting), and Docker Scout. - **Security Scoring**: Get a 0-100 score to track your security posture over time. - **Centralized Reporting**: All reports are neatly organized in `~/.docksec/results/` by default. diff --git a/docker-compose.yml b/docker-compose.yml new file mode 100644 index 0000000..94d3a80 --- /dev/null +++ b/docker-compose.yml @@ -0,0 +1,18 @@ +version: '3' +services: + web: + image: nginx:latest + ports: + - "80:80" + privileged: true + volumes: + - /var/run/docker.sock:/var/run/docker.sock + - /:/host + environment: + - MYSQL_ROOT_PASSWORD=secret + network_mode: host + pid: host + cap_add: + - ALL + security_opt: + - apparmor:unconfined diff --git a/docksec/cli.py b/docksec/cli.py index 79be716..1d3ef31 100644 --- a/docksec/cli.py +++ b/docksec/cli.py @@ -41,8 +41,9 @@ def main() -> None: from docksec.enums import LLMProvider parser = argparse.ArgumentParser(description='Docker Security Analysis Tool') - parser.add_argument('dockerfile', nargs='?', help='Path to the Dockerfile to analyze (optional when using --image-only)') + parser.add_argument('dockerfile', nargs='?', help='Path to the Dockerfile to analyze (optional when using --image-only or --compose)') parser.add_argument('-i', '--image', help='Docker image name to scan') + parser.add_argument('-c', '--compose', nargs='?', const='auto', help='Path to docker-compose file to scan.
