Clair

Clair is an open-source static analysis tool for vulnerability scanning of container images, primarily Docker and OCI images. It works by indexing container image layers and comparing them against known vulnerability databases to identify security issues. It is commonly integrated into CI/CD pipelines to automate security checks before deployment.

Also known as: Clair Scanner, Clair Vulnerability Scanner, Clair Security Tool, Clair Container Scanner, Clair Image Scanner

Why learn Clair?

Developers should use Clair to enhance container security by detecting vulnerabilities in images early in the development lifecycle, reducing risks in production environments. It is particularly valuable in DevOps and cloud-native applications where containerized deployments are frequent, helping teams comply with security standards and prevent exploits from known CVEs.
