Secure Dockerfiles with Hadolint
Dockerfile mistakes can create insecure and unreliable container images. This skill provides Hadolint workflows, rule guidance, remediation examples, and reusable CI configurations.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "container-hadolint" from https://skillstore.io/skills/agentsecops-container-hadolint.md and its manifest at https://skillstore.io/api/skills/agentsecops-container-hadolint/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "container-hadolint". Review a Dockerfile that uses a mutable base image tag and runs as root.
Expected outcome:
- High priority: add a non-root runtime user and switch before the final command.
- Reproducibility: replace the mutable base tag with an approved version or digest.
- Validation: rerun Hadolint and document any remaining suppression.
Using "container-hadolint". Recommend a CI policy for a legacy repository with several Dockerfiles.
Expected outcome:
Start with the balanced policy, report warnings without blocking, then raise thresholds after the baseline findings are assigned and remediated.
Using "container-hadolint". Explain a warning about unpinned operating system packages.
Expected outcome:
Unpinned packages reduce reproducibility and can introduce unexpected updates. Pin supported versions and keep update, installation, and cache cleanup in one layer.
Security Audit
Medium RiskMost alerts are false positives from Markdown, reference links, placeholder credentials, and examples labeled as insecure. Actionable risks include unsafe CI filename handling and unverified latest-binary downloads. Mutable CI dependencies add supply-chain exposure, while no prompt injection or malicious intent was found.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Review a Dockerfile
Identify lint findings, understand their impact, and receive focused remediation steps before building an image.
Standardize CI checks
Adapt the supplied workflow and configuration templates to enforce shared Dockerfile policies.
Assess container controls
Compare Dockerfile practices with selected security guidance and document prioritized remediation.
Try These Prompts
Review [Dockerfile path] with Hadolint. Explain each finding in plain language and suggest the smallest secure change.
Compare the strict, balanced, and permissive configurations for [project context]. Recommend one and explain every necessary customization.
Design a Hadolint check for [GitHub Actions or GitLab CI]. Pin dependencies, handle all filenames safely, and define failure thresholds.
Analyze Hadolint results for [repository]. Group root causes, prioritize security impact, identify justified suppressions, and propose a phased remediation plan.
Best Practices
- Use the balanced configuration as a baseline, then document every override and ignored rule.
- Pin CI actions, container images, and downloaded binaries to immutable versions with integrity verification.
- Combine Hadolint with image, vulnerability, and secret scanning for broader container assurance.
Avoid
- Do not treat a clean Hadolint result as proof that a container image is secure.
- Do not copy mutable download or CI examples into production without pinning and verification.
- Do not suppress findings globally before confirming their context and security impact.
