Canonical (Chiseled Ubuntu)

Distroless-style chiseled slices of Ubuntu with up to 12 years of CVE maintenance under Ubuntu Pro, from the company behind the most-deployed cloud Linux.

best_for

Ubuntu-standardized enterprises with long-lived services that care about decade-scale maintenance more than catalog breadth.

strengths

  • Longest security maintenance window in the set: up to 12 years via Ubuntu Pro / Legacy add-on
  • glibc Ubuntu compatibility: what runs on Ubuntu runs in chiseled Ubuntu
  • Everything LTS program extends CVE maintenance to arbitrary open source dependencies
  • Microsoft partnership ships chiseled .NET images, a strong enterprise proof point

weaknesses

  • Chisel tooling and slice definitions carry a learning curve versus buying a finished catalog
  • Application image catalog is thinner than Chainguard or Bitnami
  • Value concentrates if you are already an Ubuntu shop; weaker standalone story otherwise
