About
Docker Hardened Images is a catalog of secure, minimal, production-ready container images published through Docker Hub. The catalog includes hardened base images and packaged components for common runtimes, infrastructure tools, and Kubernetes add-ons.
The free offering is centered on the hardened images catalog, where individual images can be used without charge. The catalog spans multiple technical areas, including databases, monitoring, networking, security, developer tools, and language runtimes.
- Secure minimal container images
- Production-ready hardened image catalog
- Debian and Alpine image variants
- linux/amd64 and linux/arm64 support
- CIS, FIPS, and STIG compliance options
- Helm chart and image packages
Free Tier Value
The page explicitly states “They’re free to use,” and no caps, credits, trials, or paid plan pricing are shown in the provided text. Per the rules, an always-free offering with no visible limits is treated as unbounded, so the free tier value is null and always_free_unbounded is true. Because the page includes sign-in/sign-up flows and does not explicitly say no credit card is required, no_cc_required is false.
