Agent request
Review the Skillstore skill "containerizing-applications" from https://skillstore.io/skills/asmayaseen-containerizing-applications.md and its manifest at https://skillstore.io/api/skills/asmayaseen-containerizing-applications/manifest. Verify the artifact. Stop and obtain explicit user consent before installing or changing files.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "containerizing-applications". Containerize a FastAPI service that uses PostgreSQL and listens on port 8000.
Expected outcome:
- A multi-stage Python image with a non-root runtime user.
- A Compose service connected to PostgreSQL through its internal service name.
- A loopback health check with startup timing and database dependency guidance.
Using "containerizing-applications". Prepare a Next.js frontend and API for Kubernetes deployment.
Expected outcome:
- Separate frontend and API image plans with build-time and runtime variables.
- A Helm structure covering deployments, services, ingress, probes, and limits.
- Notes for browser URLs, internal service discovery, CORS, and secret references.
Using "containerizing-applications". Review an existing container build for production security.
Expected outcome:
- Findings for runtime users, image tags, build context, secrets, and package installation.
- Recommended vulnerability scanning, signature verification, and software bill of materials checks.
- Prioritized changes with deployment-specific validation steps.
Security Audit
High Riskv10 • 7/23/2026 Open versioned report
Most static alerts are false positives caused by Markdown syntax, local networking examples, protected secret mounts, and exclusion rules. Context review found mutable CI action references and distroless examples that may run as root. No prompt injection or credential exfiltration intent was found.

Mutable CI Action References
CI examples reference actions through mutable branch or version tags. An upstream tag change can execute altered code in privileged workflow jobs.
The files explicitly use @master, @v3, and @v5 instead of immutable commit SHAs. Mutable workflow references are a well-established CI supply-chain risk.
High
Distroless Examples May Run as Root
The examples claim unqualified distroless images run as non-root, but they omit USER and do not select a nonroot image variant. Generated containers may run as root.
Both examples use the default distroless tag while asserting non-root behavior. Distroless publishes a separate nonroot variant, and neither example sets USER.

What You Can Build
Package a Web Application
Create coordinated Dockerfiles and Compose services for a frontend, API, database, and health checks.
Prepare Kubernetes Packaging
Translate container requirements into a Helm chart structure with services, configuration, ingress, and resource limits.
Strengthen Container Builds
Review image stages, runtime users, secret handling, vulnerability scans, and software bill of materials generation.
Try These Prompts
Create a Basic Dockerfile
Create a production Dockerfile for my [runtime] application. It starts with [command], listens on [port], and installs dependencies from [file].
Build a Compose Environment
Create Docker Compose configuration for [services]. Include internal networking, environment placeholders, health checks, startup dependencies, and persistent storage where required.
Package with Helm
Design a Helm chart for [application]. Include deployments, services, ingress, configuration, secret references, probes, resource limits, and environment-specific values.
Audit a Container Architecture
Review my container files for image provenance, root execution, leaked secrets, unsafe networking, missing probes, mutable tags, and deployment reliability risks.
Best Practices
- Pin base images and CI actions to reviewed immutable references.
- Use multi-stage builds, non-root runtime users, minimal images, and explicit health checks.
- Keep secrets outside images and pass them through dedicated secret mechanisms.
Avoid
- Do not place credentials, environment files, or private keys in build contexts.
- Do not use localhost for communication between separate containers.
- Do not deploy mutable latest tags or assume an image runs as non-root.
Frequently Asked Questions
Which application stacks are included?
The examples cover FastAPI, Next.js, and general container workflows. Adapt package commands and runtime details for other stacks.
Does the skill run Docker or Kubernetes commands?
No. It provides configuration patterns and command guidance. Users must review and execute commands in their own environments.
Are generated files production ready?
They are starting points. Validate images, ports, users, secrets, probes, resources, network policy, and deployment requirements before release.
How should build secrets be handled?
Use BuildKit secret mounts or platform secret stores. Never copy secret files into image layers or commit them.
Can it create Helm charts?
It outlines chart structure and common values for deployments, services, configuration, secrets, ingress, probes, and resource limits.
Does it include security scanning guidance?
Yes. It covers Trivy scanning, SBOM generation, image signatures, minimal images, non-root execution, and sensitive build-context exclusions.
