Why does Syft crash when scanning my container?

Usually memory issues. I've seen it eat tons of RAM scanning big Node.js containers - like 10-12GB or something crazy. Give it 8GB minimum or it'll crash your build agents. Also, the default 2-minute timeout is way too short. Use `--timeout=30m` for anything real.

Does Syft work with my company's private registry?

Sometimes. Docker credentials work most of the time. AWS ECR can be tricky with IAM permissions. Azure Container Registry auth is hit or miss. The `--registry-auth-file` flag usually helps.

How do I stop Syft from generating huge SBOM files?

You don't really. Modern apps have tons of dependencies - that simple React app probably has hundreds of NPM packages. Compress the files and deal with it. Syft JSON format includes everything, so files get big.

Which output format should I actually use?

Syft JSON format if you want all the metadata - files get big but it's the most complete. CycloneDX if your security team specifically wants that format. SPDX for compliance requirements. GitHub format exists but I haven't found much use for it.

Why does scanning take forever?

Modern containers are big. Your "lightweight microservice" is probably 800MB because it includes tons of base image stuff. Java fat JARs take 20+ minutes to scan. Node.js containers with all those dependencies take a while too. Recent updates help but can't fix fundamentally large images.

Can I scan my source code instead of containers?

Yeah, `syft dir:/path/to/code` works well. You skip all the base image noise and get cleaner results. Point it at your project root - still takes time but the results are more focused.

Does this work with Kubernetes?

Runs in pods fine if you give it enough resources. ImagePullSecrets can be tricky to configure. Most people run it in CI/CD before deploying rather than in-cluster.

What if Syft finds nothing?

Your container might be really minimal (like Distroless), Syft might not support your package manager, or you hit a bug. Check the supported ecosystems list - if your package manager isn't there, you're out of luck.

How does this compare to Trivy?

Trivy's faster but misses some packages. Syft finds more but uses more RAM. Both work fine - depends if you want speed or completeness. I use Syft + Grype since they work well together.

Why does my CI pipeline keep timing out?

The default 2-minute timeout is way too short for real containers. Set your pipeline timeout to 30+ minutes for anything substantial. Also bump memory limits or Syft will get killed mid-scan.

Is the enterprise version worth it?

Only if you need centralized management or commercial support. Also depends if your compliance team demands vendor support contracts. Some enterprises won't touch open source without a phone number to yell at. The open source version handles most real use cases. Pricing isn't terrible if your company needs the enterprise features.

Can I trust the results?

Mostly, yeah. Syft misses some edge cases with custom build systems or unusual packaging. More false negatives than false positives. It's way better than manual dependency tracking and good enough for most compliance needs.
