Expert Docker Code Review for AI-Built Apps
Docker is the standard for containerizing applications. AI tools generate Dockerfiles that build and run, but often produce bloated images, run as root, expose secrets in layers, and lack production-grade configuration.
Common Docker issues we find
Real problems from Docker codebases we've reviewed.
Running as root user
Containers running processes as root, so a container breakout gives the attacker root access to the host system.
Secrets baked into image layers
API keys, database passwords, or .env files copied into the Docker image during build, permanently stored in image layers even if deleted later.
Bloated image size
Using full OS base images (ubuntu, node:latest) instead of slim or alpine variants, resulting in 1GB+ images that are slow to pull and deploy.
No multi-stage build
Build dependencies (compilers, dev packages) included in the production image, increasing size and attack surface.
Missing health checks
No HEALTHCHECK instruction in the Dockerfile, so orchestrators can't detect when the application inside the container is unhealthy.
Unpinned base image tags
Using 'latest' or major version tags that can change between builds, causing inconsistent behavior and broken deployments.
Docker production checklist
Key checks before deploying your Docker app.
Non-root USER specified in Dockerfile
No secrets or .env files in image layers
Multi-stage build separating build and runtime
Slim or alpine base image used
Base image tags pinned to specific versions
HEALTHCHECK instruction defined
.dockerignore excludes node_modules, .git, and .env files
Container runs with read-only filesystem where possible

Frequently asked questions
Is my AI-generated Dockerfile secure?
Almost never. Common issues include running as root, secrets in image layers, and bloated base images. We audit your Dockerfile and container configuration to meet production security standards.
How do I make my Docker image smaller?
We implement multi-stage builds, switch to alpine or slim base images, optimize layer caching, and remove build dependencies from the production image — often reducing image size by 80% or more.
Can you containerize my app?
Yes. We create optimized Dockerfiles with multi-stage builds, proper security configuration, health checks, and docker-compose setups for local development.
Should I use Docker or serverless?
Docker for long-running processes, WebSocket connections, or when you need full control. Serverless for request-driven APIs with variable traffic. We recommend based on your architecture.
