How can I enhance security in my CircleCI Docker setup?

To enhance security in your CircleCI Docker setup, consider using Docker's built-in security features, such as user namespaces and seccomp profiles.

What are user namespaces and how do they help?

User namespaces allow you to map user IDs inside the container to different IDs on the host, reducing the risk of privilege escalation.

Are there any specific CircleCI configurations I should use?

Yes, you can use CircleCI's built-in security features like context and environment variables to manage sensitive data securely.

What about scanning images for vulnerabilities?

You should integrate a vulnerability scanner like Trivy or Clair into your CI/CD pipeline to automatically scan Docker images for known vulnerabilities.
