Increase in build speed after Earthly


It took literally just going from Dockerfile to Earthfile to bring build times from 45-ish minutes down to probably 15 or 20.

Introducing Earthly
Fast, consistent builds that are super simple to use
Write once, run anywhere
  • Execute CI pipelines on your laptop, remotely, or in any CI
  • Easily reproduce CI failures locally
  • Containers make builds self-contained, isolated, consistent, and portable
  • Correct execution, regardless of the environment
  • New colleagues get started fast: no special configuration necessary
Super simple, not just for the build guru
FROM golang:1.21-alpine3.19
RUN apk --update --no-cache add git
WORKDIR /go-example
BUILD +build
BUILD +lint
COPY main.go .
RUN go build -o build/go-example main.go
SAVE ARTIFACT build/go-example AS LOCAL build/go-example
RUN go install
COPY main.go .
RUN golint -set_exit_status ./...
  • Quickly grasp Earthfiles without prior knowledge
  • Syntax that is easy to write and understand by all engineers
  • It's like Dockerfile and Makefile had a baby
Compatible with every language, framework, and build tool
  • Works with the compilers and build tools you use.
  • If it runs on Linux, it runs on Earthly.
  • You don’t have to rewrite your existing builds or replace your package.json, go.mod, or build.gradle files.
  • Use Earthly as a wrapper around your existing builds and get Earthly’s consistency, parallelization, and caching.
Compatible with every language, framework, and build tool
Great for monorepos and polyrepos
  • Works with both monorepos and polyrepos
  • Builds can be split across multiple subdirectories or even repositories
  • Reuse, don't repeat: reference builds, recipes, artifacts, and images from other locations

Automatic caching and parallel execution
  • Automatically caches build results at each step of the build. Repeated steps are skipped each build.
  • Automatically executes build targets in parallel whenever possible.

If your build has multiple steps, Earthly:

  • Builds a directed acyclic graph (DAG).
  • Isolates execution of each step.
  • Runs independent steps in parallel.
  • Caches results for future use.
Automatic caching and parallel execution
Never write the same code in multiple builds again
Never write the same code in multiple builds again
  • Reuse targets, artifacts, and images across multiple Earthfiles, even ones in other repositories.
  • Import from any other build in a single line.
  • Create vast and efficient build hierarchies that only execute steps impacted by your changes.
Open Source and a Strong Community
Open source projects benefit from a collaborative community. Earthly encourages contributions.
