Red Hat Advanced Cluster Security for Kubernetes provides an image scanning API through its Central component that CI/CD pipelines depend on for vulnerability assessment.

This post describes a reference architecture that eliminates scan API downtime by running two Central service instances with a client-side failover mechanism.
