FAQ
What does this tool tell you?
Packer template reference — builders, provisioners, and post-processors at a glance.
What affects the result most?
Packer HCL2: source blocks define builder, build blocks orchestrate provisioners. Builders: amazon-ebs, googlecompute, digitalocean, vagrant — platform-specific image creation. Provisioners: shell, ansible, file — run in order, all must succeed for image creation.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
