Earthly Build File vs Dockerfile: Format Comparison
Key differences between the two formats
| Feature | Earthfile | Dockerfile |
|---|---|---|
| Syntax style | Earthly-specific commands (BUILD, COPY, RUN) | Standard Docker commands (FROM, COPY, RUN) |
| Multi-stage builds | Automatic multi-stage optimization | Manual multi-stage definition with AS keyword |
| Caching | Advanced incremental caching with cache mounts | Standard layer caching |
| Target system | Can build multiple targets in one file | Single image per Dockerfile |
| Dependencies | Built-in dependency management between targets | Manual dependency handling via multi-stage |
| Compatibility | Requires Earthly CLI | Universal Docker support |
| Use case | Complex multi-service builds, monorepos | Single service containers, CI/CD pipelines |
When to Convert
Common scenarios where this conversion is useful
CI/CD pipeline migration
Convert Earthly builds to standard Docker for compatibility with CI systems that don't support Earthly, like legacy Jenkins, Azure DevOps, or AWS CodeBuild.
Team workflow standardization
Migrate team builds from Earthly to Docker when adopting organization-wide Docker standards or when new team members lack Earthly experience.
Multi-build system compatibility
Generate Docker-compatible builds alongside Earthly workflows for projects that need to support both build systems during transition periods.
Legacy infrastructure support
Convert Earthly builds to Dockerfile format for deployment on legacy container platforms that only support standard Docker builds.
Who Uses This Conversion
Tailored guidance for different workflows
DevOps Engineers
- Migrate CI/CD pipelines from Earthly to standard Docker for broader tool compatibility
- Convert Earthly builds to Docker format for deployment on container platforms without Earthly support
Platform Engineers
- Standardize container builds across teams by converting Earthly builds to Docker for organization-wide consistency
- Generate Docker-compatible builds for legacy systems that cannot install or support Earthly CLI
Software Developers
- Convert personal Earthly projects to Docker format for sharing with team members unfamiliar with Earthly
- Generate standard Docker builds from Earthly files for deployment to cloud platforms with Docker-only support

Frequently Asked Questions
Yes. Multi-target Earthfiles are converted to equivalent multi-stage Dockerfiles using the AS keyword to name intermediate stages. Each Earthly target becomes a Docker build stage.
Cache mounts are converted to equivalent Docker BuildKit cache mount syntax when possible. Some advanced Earthly caching features may require manual optimization in the output Dockerfile.
BUILD commands that reference other targets are converted to COPY --from statements in Docker multi-stage builds, maintaining dependency relationships between build stages.
No. The entire conversion happens in your browser using JavaScript. Your build files never leave your device, making it safe for proprietary build configurations.
The converter maintains Dockerfile best practices like layer optimization and proper ordering of commands. However, some Earthly-specific optimizations may require manual tuning.
Standard Earthly commands (FROM, RUN, COPY, WORKDIR, ENV) convert directly. Custom commands and advanced Earthly features may need manual adjustment in the output Dockerfile.
Earthly secret mounts are converted to Docker secret mount syntax compatible with Docker BuildKit. Secret references are preserved but may need environment variable adjustments.
Import statements are preserved as comments in the output Dockerfile with guidance on how to manually incorporate imported functionality into the Docker build.
Yes. FROM statements in Earthfiles are converted to equivalent FROM statements in Dockerfiles, preserving image names, tags, and registry references.
Yes, completely free with no limits on file size or number of conversions. No account required.
Yes. Since conversion runs in your browser, file size is limited only by your device's memory. Complex multi-target builds are fully supported.
The converter produces syntactically correct Dockerfiles that preserve the core build logic. Some manual optimization may be needed for complex Earthly-specific features.
