Community features

DHI's core features are free to use, share, and build on under Apache 2.0.

  • Near-zero CVEs: continuously scanned and patched to maintain minimal known vulnerabilities
  • Distroless variants: remove unnecessary components, reducing attack surface by up to 95%
  • Non-root execution: containers run as non-root by default
  • Hardened system packages: system packages built from source, cryptographically signed, and verified by Docker
  • SLSA Build Level 3 provenance, signed SBOMs, VEX statements, and cryptographic signatures on every image
  • Built on Alpine and Debian with glibc and musl variants; dev and runtime image variants available
  • Works with existing Docker workflows, CI/CD pipelines, and tools with no retooling required
  • Helm charts: Docker-provided charts built from upstream sources, tested for compatibility with DHI, and available as OCI artifacts in the DHI catalog; include SLSA Level 3 provenance, SBOMs, and cryptographic signing

Select and Enterprise features

For organizations with strict security or compliance requirements:

  • 7-day SLA for critical and high severity CVE remediation
