Configuring OpenShift for FIPS 140-3 Compliance

The cluster was ready. Encryption modules stood idle, waiting for the signal. You know the rules: without FIPS 140-3 compliance, the platform is not approved for federal or regulated workloads. Openshift can meet that bar, but only if you configure it with precision.

FIPS 140-3 is the current U.S. government standard for cryptographic modules. It sets strict requirements for how cryptographic algorithms and keys are implemented, tested, and validated. Openshift, built on Kubernetes, supports deploying workloads that run entirely in FIPS-compliant mode. The key is enabling FIPS mode across the operating system, container images, and any service offering encryption.

On Red Hat Enterprise Linux CoreOS, you can enable FIPS mode during installation by setting the appropriate boot parameters. This ensures system libraries use only FIPS-approved algorithms. Every container image you build and deploy must also be compiled against FIPS-validated OpenSSL and other approved modules. That means checking dependencies, rebuilding with the correct libraries, and verifying the chain of compliance.

Cluster-wide, OpenShift needs its control plane components—API server, etcd, ingress controllers—to run with FIPS-compliant builds. Etcd encryption at rest, TLS termination, and service-to-service communication must all use approved cipher suites. Audit logs should confirm no disallowed algorithms are in use.

Openshift’s compliance operator can help verify FIPS 140-3 configurations. You can integrate automated tests that fail builds when non-compliant modules are detected. Security teams should review every change to ensure continuous alignment with FIPS 140-3 requirements, especially in CI/CD pipelines.

Without full-stack FIPS compliance in OpenShift, workloads could fail audit and trigger costly remediation. With it, you get a hardened platform ready for regulated industries, defense contracts, and federal deployments.
