YAML Validator: Check Docker Compose and Kubernetes Configs
Validate YAML syntax for Docker Compose, Kubernetes, CI/CD pipelines, and configuration files. Catch errors before deployment.
Why Validate YAML?
YAML syntax errors can break your deployments:
- Docker Compose won't start - Kubernetes pods fail to create - CI/CD pipelines abort - Applications misconfigure
Common YAML Mistakes
1. Wrong indentation - YAML requires spaces, not tabs 2. Missing colons - Key-value separator forgotten 3. Unquoted special chars - : @ * in values need quotes 4. Duplicate keys - Same key twice at one level
Configuration Files That Use YAML
- docker-compose.yml - Container orchestration - Kubernetes manifests - GitHub Actions workflows - GitLab CI/CD pipelines - Ansible playbooks
