The init command bootstraps a .preflight.yaml schema file for your project. It can infer variable definitions from an existing .env file or fetch a complete schema from a remote URL.

​
Usage

dotset preflight init [options]

​
Options

OptionDescriptionDefault
-f, --file <path>Path to the .env file to scan.env
-o, --output <path>Path where the schema will be created.preflight.yaml
-r, --remote <url>Initialize from a remote schema URL-
--forceOverwrite the schema file if it already exists-

​
Remotes (MVP Feature)

You can now initialize your project using a shared schema hosted on a remote server (e.g., GitHub, S3, or your internal developer portal). This ensures consistency across microservices. 
dotset preflight init --remote https://raw.githubusercontent.com/org/repo/main/.preflight.yaml

​
Inference Engine

When initializing from a local .env file, Preflight automatically infers:
  • Types: Detects URLs, ports, emails, and booleans.
  • Sensitivity: Automatically marks secrets like API_KEY, PASSWORD, and TOKEN as sensitive.
  • Requirements: All discovered variables are marked as required: true by default.
