Generate valid YAML files instantly for Docker, Kubernetes, CI/CD pipelines, and configuration management. Create sample YAML with proper indentation and syntax.
What is a YAML File?
YAML (YAML Ain't Markup Language) is a human-readable data serialization format designed for configuration files and data exchange. It uses indentation to represent structure, making it cleaner than JSON or XML. YAML supports key-value pairs, arrays, nested objects, multi-line strings, and comments—features that make it ideal for config files. Common in DevOps, YAML is the format of choice for Docker Compose, Kubernetes manifests, GitHub Actions, CI/CD pipelines (GitLab CI, CircleCI), Ansible playbooks, and application configuration (Spring Boot, Rails). Both .yaml and .yml extensions are valid, with .yaml being the official recommendation.
Why Use Sample YAML Files?
Test YAML parsers and configuration loaders without writing from scratch
Learn YAML syntax with realistic examples from Docker, Kubernetes, CI/CD
Quickly prototype infrastructure-as-code configurations
Validate YAML structure and indentation rules in your applications
Get started with Docker Compose or Kubernetes without configuration errors
Create GitHub Actions workflows with proper syntax
Experiment with different YAML features like anchors, aliases, and multi-line strings
Save time by starting with templates instead of blank files
Common Use Cases
Docker Compose Files
Generate docker-compose.yml files for multi-container applications. Define services, networks, volumes, environment variables, and dependencies. Perfect for local development environments, microservices architecture, and container orchestration.
Kubernetes Manifests
Create Kubernetes Deployment, Service, ConfigMap, and Secret YAML files. Define container specs, resource limits, replicas, labels, and selectors. Use for deploying applications to Kubernetes clusters with proper configuration.
CI/CD Pipeline Configuration
Build GitHub Actions workflows, GitLab CI, CircleCI, or Azure Pipelines configuration files. Define build steps, test jobs, deployment stages, environment variables, and triggers for automated software delivery.
Application Configuration
Generate config.yml files for applications built with Spring Boot, Ruby on Rails, or other frameworks. Define database connections, API keys, feature flags, logging levels, and environment-specific settings in readable YAML format.
Generator Features
Multiple templates: Generic Config, Docker Compose, GitHub Actions, Kubernetes, Custom
Proper indentation (2 or 4 spaces) and YAML syntax validation
Support for nested objects, arrays, and multi-line strings
Pre-filled sample data that you can customize for your needs

Preguntas Frecuentes
What is a YAML file?
YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files. It uses indentation to represent structure and supports strings, numbers, booleans, lists, and nested objects.
What is the difference between .yaml and .yml?
Both .yaml and .yml are valid YAML file extensions. The .yaml extension is officially recommended by the YAML specification, while .yml became popular due to legacy DOS 8.3 filename restrictions. Both work identically.
Where are YAML files commonly used?
YAML files are widely used in Docker Compose, Kubernetes manifests, GitHub Actions workflows, CI/CD pipelines (GitLab CI, CircleCI), configuration files (Spring Boot, Rails), and infrastructure-as-code tools like Ansible.
Is YAML better than JSON?
YAML is more human-readable with cleaner syntax and supports comments, making it ideal for configuration files. JSON is more widely supported in APIs. YAML is a superset of JSON, so valid JSON is also valid YAML.
Can I use this YAML generator for free?
Yes! This YAML generator is completely free with no signup required. All file generation happens in your browser, ensuring your data remains private and secure.
What templates are available?
We offer templates for common use cases: Generic Config, Docker Compose, GitHub Actions, Kubernetes Deployment, and Custom. Each template includes realistic sample data you can customize.
