.env to Docker Compose & K8s ConfigMap Converter
Docker & K8sConvert .env environment configuration files into Docker Compose environment blocks and Kubernetes ConfigMap manifests directly in your browser. Sanitize quotes, format multiline strings, and generate deployment-ready configurations with zero cloud uploads.
.env to Docker Compose & K8s ConfigMap Converter
Convert .env variables to Docker Compose environment YAML, Kubernetes ConfigMaps, and bash export statements.
Interactive .env to Docker Compose & K8s ConfigMap Converter Workspace
Convert .env key-value files to Docker Compose YAML (list or dictionary syntax), Kubernetes ConfigMap YAML, and bash export statements with automatic type handling, comments, and variable quotation in your browser.
How This Tool Works (100% Client-Side Engine)
The tool parses the .env string line by line using regex to separate comments, keys, and values while unescaping quotes. It constructs formatted YAML structures according to Docker Compose specifications and Kubernetes v1 API ConfigMap schemas.
Step-by-Step Guide
Paste .env File Contents
Drop your .env file into the workspace or paste raw KEY=VALUE pairs into the editor.
Select Output Format
Choose Docker Compose (List or Map syntax), Kubernetes ConfigMap YAML, or Docker Run command flags.
Copy Formatted Manifest
Review the formatted YAML with proper 2-space indentation and copy it directly to your deployment repository.
Why Use This Tool: Privacy & Performance
Transitioning application configuration from local .env files into containerized deployments (Docker Compose or Kubernetes) requires tedious manual reformatting: converting KEY=VALUE pairs into YAML dictionary structures, indenting environment lists, handling quotation marks, or structuring k8s ConfigMap data blocks. Accidentally mishandling syntax leads to container startup failures. Furthermore, pasting .env files containing confidential database credentials, API secrets, and server ports into public online formatters is an extreme security risk. ToolByte .env to Docker Compose & K8s ConfigMap Converter runs completely within your local browser sandbox. It parses KEY=VALUE syntax, handles comments and quoted strings, and exports cleanly formatted Docker Compose YAML or Kubernetes ConfigMap YAML in seconds with zero data exposure.
Common Use Cases & Workflows
Migrating Local Projects to Docker Compose
Transform local .env files into docker-compose.yml environment: or env_file: blocks with proper YAML indentation.
Generating Kubernetes ConfigMaps
Convert application environment variables into production-ready Kubernetes ConfigMap and Secret manifest templates.
Sanitizing Environment Variables for CI/CD
Standardize variable naming and formatting before copying keys into GitHub Actions or GitLab CI secret stores.
Docker Run Command Environment Flag Creation
Convert .env files into a single inline docker run -e KEY=val -e KEY2=val command string.
