How Aikido Hardens Your Base Images

Discover Vulnerable Base Images

Secure the source of your containers. Aikido maps every image to its base and shows where a Root-maintained ELS image can remove risk fast.‍

  • Image → Base Mapping: See which services inherit each base.‍
  • Layer-Aware CVEs: Focus on HIGH/CRITICAL issues in the base layer.
  • ‍Root ELS Availability: Instantly know when a Root ELS replacement exists for your current base.‍

Find & Fix at the Source Layer

Swap to a hardened ELS image. No rewrites, minimal change risk. Downstream containers get safer by default. Prioritized Suggestions: Aikido surfaces the ELS option where it cuts the most risk.

  • Prioritized Suggestions: Aikido surfaces the ELS option where it cuts the most risk.
  • One-Click AutoFix PRs: Update the FROM line via PR or copy the Dockerfile snippet.
  • Compatibility First: Stay on the same distro/major version; Aikido backports the patches.

Continuous & Proactive Hardening

Aikido monitors new ELS builds and prompts upgrades, without forcing full OS jumps.

  • Ongoing Updates: Alerts when a newer ELS build is available
  • Policy & Gating: Block merges that ignore available ELS fixes.‍
  • Trusted Supply: ELS images maintained by Root, hosted via docker.aikido.io, surfaced by Aikido.

FAQ

What are the main features of ELS containers?

Auto-discovery of vulnerable base images; a clear indication when an ELS replacement exists; one-click AutoFix PRs that update the Dockerfile; continuous prompts when newer ELS builds land; support for both amd64/arm64 architectures; policy controls to gate merges that ignore available fixes; visibility of blast radius (which services inherit each base).

What is the main value that ELS containers bring?

It lets teams remove High and Critical CVEs from base images without bumping OS versions or risking dependency breakage. By swapping the FROM line to an ELS image, you harden your base layers quickly, cut risk and audit noise, and keep delivery velocity intact.
