Validate Docker Compose Files
Edit Docker Compose File
Common Questions
What is Docker Compose?
Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application's services, networks, and volumes. Then, with a single command, you create and start all the services from your configuration.
What does this validator check for?
This validator checks for YAML syntax errors, Docker Compose schema validation, service dependencies, network configurations, volume definitions, environment variables, and other common issues in Docker Compose files. It helps identify potential problems before running your Docker Compose setup.
What Docker Compose versions are supported?
This validator supports Docker Compose file formats for versions 1, 2, 2.1, 2.2, 2.3, 2.4, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, and 3.8. The validation rules adapt based on the version specified in your compose file.
Are my Docker Compose files sent to a server?
No, all validation happens entirely in your browser. Your Docker Compose configuration is never sent to any server, ensuring your sensitive configuration data remains private and secure.
How can I fix common Docker Compose errors?
Common errors include incorrect indentation (YAML is sensitive to whitespace), missing required fields, invalid service names, incorrect volume specifications, and network configuration issues. The validator will provide specific error messages to help you troubleshoot these problems.
Can I validate Docker Compose files with environment variables?
Yes, but keep in mind that client-side validation can't resolve environment variables that would normally be available in your deployment environment. The validator will check the syntax of environment variable references but can't validate their actual values.
