Dockerfile Generator

A CLI tool for generating Docker-related configuration files.

Installation

cargo build --release

The binary will be available at target/release/dockerfile_generator

Commands

1. Generate Single File

Generate individual configuration files using the following commands:

Available file types:

• dockerfile
