Frequently Asked Questions

What types of files can I upload?

You can upload files named "Dockerfile" (with no extension) or files with .dockerfile or .txt extensions. The content should be valid Dockerfile syntax.

Is my Dockerfile uploaded to your servers?

No, all processing happens locally in your browser. Your Dockerfile never leaves your computer.

Can I edit the Dockerfile in this viewer?

Currently this is a read-only viewer. For editing, we recommend using a dedicated code editor like VS Code.

Does this tool validate my Dockerfile syntax?

This tool provides syntax highlighting but doesn't perform full validation. For complete validation, you should use the docker build command.
