The exposure of user data from container registries highlights the importance of securing the entire software supply chain. Container images pulled from public registries can contain vulnerabilities or even malicious code if not properly verified.
Securing Your Container Supply Chain
Running a private registry gives you full control over which images are available to your infrastructure. Harbor, GitLab Container Registry, and AWS ECR provide enterprise-grade features including vulnerability scanning and role-based access control.
Image signing with Docker Content Trust ensures that only images signed by trusted publishers are pulled and run. This cryptographic verification prevents man-in-the-middle attacks and image tampering throughout the distribution pipeline.
Regularly scan your container images for known vulnerabilities using tools like Trivy, Clair, or Anchore. Automate scanning in your CI/CD pipeline to catch issues before they reach production environments.
