Can this tool catch a malformed or misnamed artifact before deployment?

It will surface MIME type based on file extension and exact size in bytes, which catches common issues like a config file renamed to the wrong extension or a truncated archive. It does not perform binary inspection or hash verification.

How does the JSON output fit into a deployment audit log?

Each file record is a flat JSON object with consistent fields — name, size_bytes, mime_type, timestamps — that maps directly to most logging schemas. Store the full report alongside the deployment run metadata for a complete artifact provenance record.

What is the maximum batch size?

Up to 50 files or 2GB total per batch. For large release bundles, split across multiple runs and merge the JSON outputs before comparison.

Does this replace checksum verification in a secure pipeline?

No — metadata reports and checksum verification are complementary. Metadata catches format and size anomalies; checksums verify file integrity. Both should be present in a security-conscious release pipeline.

File Metadata Reports for DevOps Engineers Validating Build Artifacts

Build artifacts that arrive in the wrong format or at an unexpected size are a silent failure mode in deployment pipelines. The File Metadata Report tool generates a structured JSON record for every uploaded file — name, size in bytes, MIME type, and timestamps — giving you a fast, reproducible inspection step before files enter your release process.

DevOps engineers routinely handle ZIP archives, JARs, tarballs, configuration bundles, and mixed-format artifact drops from upstream build systems. Verifying these manually before promotion to staging or production is tedious and inconsistently applied. A metadata report run as a pre-deployment gate takes seconds and produces a machine-readable record that can be stored alongside the deployment log, compared against an expected manifest, or flagged in a Slack alert if something looks off.

Deliteful accepts ZIP, PDF, CSV, JSON, Excel, DOCX, and common image formats — covering most artifact and documentation types in a typical release bundle. Batches up to 50 files or 2GB run in a single pass. The flat JSON output structure requires no parsing gymnastics and drops cleanly into existing logging or audit tooling.

How it works

1
Upload the artifact bundle or file batch
Drop the build output, config package, or mixed artifact set — up to 50 files per run.
2
Receive the JSON metadata report
Each file returns a record with name, size_bytes, mime_type, and filesystem creation and modification timestamps.
3
Integrate into your pre-deployment validation
Compare against expected specs, log alongside the release record, or trigger a hold if any file deviates from expected size or type.
