About .env → YAML
The Dotenv (`.env`) to YAML Converter transforms flat environment variable files (`DATABASE_URL=postgres://...`) into structured YAML configuration files, Docker Compose `environment:` blocks, and Kubernetes ConfigMap manifests.
How to Use .env → YAML
Step 1
Paste your `.env` file content into the input pane.
Step 2
Select YAML output preset (Standard YAML, Docker Compose, or Kubernetes ConfigMap).
Step 3
Review the generated YAML configuration.
Step 4
Click "Copy YAML".
Practical Use Cases for .env → YAML
Generating Docker Compose Environment Blocks from `.env`
Convert `.env` files into indented `environment:` sections for `docker-compose.yml` service definitions.
Creating Kubernetes ConfigMap & Secret Manifests
Transform application `.env` variables into Kubernetes `kind: ConfigMap` YAML resources with `data:` mappings.
Input & Output Examples
Converting `.env` to Docker Compose YAML
`PORT=3000\nNODE_ENV=production\nDB_HOST=localhost`
`environment:\n - PORT=3000\n - NODE_ENV=production\n - DB_HOST=localhost`

Key Terminology & Definitions
