Missing container security hardening

Vibe & agenticAlgorithms & data structuresMid–Senior~13 min

You asked an AI to "containerize this Python FastAPI service for production." It gave you this and it runs. What hardening did it skip, and why does it matter in a shared cluster?

Implement
effective_runtime_user(instructions: list[str]) → str
Examples
in[["from|python:3.12","copy|requirements.txt","run|pip install -r requirements.txt","copy|.","cmd|uvicorn"]]out"root"
in[["from|python:3.12-slim","run|useradd -m app","user|app","cmd|uvicorn"]]out"app"
in[["from|python:3.12","user|builder","from|python:3.12-slim","copy|--from=0 /app /app","cmd|uvicorn"]]out"root"
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
