Dockerfile COPY vs ADD Instruction Security Auditor

Audits Dockerfile build instructions for secure use of COPY over potentially unsafe ADD operations.

Notice: engineering verification utility. Use test or de-identified data and verify results independently before relying on them.

How it works

Standard: CIS Docker Benchmark / Dockerfile Best Practices

Formula: Flag instances of ADD instruction unless remote URL extraction or tar extraction is explicitly required

Checks: Dockerfile instruction parsing
