Dockerfile Generator

Writing a Dockerfile from scratch forces you to recall the right base image, the layer order and the security best practices. This generator starts from already-tested templates for the most common stacks, Node, Python, Go and a static Nginx site, and builds the file in your place.

You can switch on the features that set an amateur Dockerfile apart from a professional one: a multi-stage build to shrink the image, a healthcheck so the orchestrator knows whether the container is healthy, and running as a non-root user, which makes a real difference to security. You pick what you need and get a coherent Dockerfile.

Generation runs in the browser and the file comes out ready to copy into the project root. Instead of staring at a blank page, you begin from a solid starting point.
