DockerLint: Automated Dockerfile Security Linting
DockerLint is a lightweight Python CLI tool that performs automated security linting on Dockerfiles. It identifies common misconfigurations, security risks, and best-practice violations in your container definitions.
Features
- Fast, dependency-free Python CLI
- Detects privilege escalation risks
- Identifies missing security contexts
- Checks for outdated base images
- Validates layer caching strategies
- JSON and human-readable output
Quick Start
pip install dockerlint
dockerlint scan Dockerfile
Why Use DockerLint?
Docker security is often overlooked in the CI/CD pipeline. DockerLint catches issues before they reach production:
- Run as non-root: Enforces principle of least privilege
- Multi-stage builds: Reduces final image size and attack surface
- Signed base images: Verifies container image provenance
- Health checks: Ensures containers can signal readiness
