Repeatable Builds
Earthly is a syntax for defining your build. It works with your existing build system. Get repeatable and understandable builds today.
Earthfile
FROM golang:1.13-alpine3.11
build:
COPY main.go .
RUN go build main.go
SAVE ARTIFACT main AS LOCAL main
Over 500 CI pipelines run Earthly.

Understandable and Repeatable Build Scripts with Earthly
❤️ Makefile + Dockerfile = Earthfile
It's like Makefile and Dockerfile had a baby. Earthly takes some of the best ideas from Makefiles and Dockerfiles and combines them into one specification.

Building things
Reproduce CI failures
Earthly builds are self-contained, isolated and repeatable. Regardless of whether Earthly runs in your CI or on your laptop, the build will run the same way. This allows for faster iteration on the build scripts and easier debugging. No more git commit -m "try again" .

"
Earthly is a pragmatic and incremental solution to a thorny problem that all organizations face. I'm extremely excited about Earthly bringing this functionality to existing container based build systems without requiring an extremely expensive retooling effort on top of something like Bazel.
Envoy is an open source edge and service proxy, designed for cloud-native applications.

Large organizations like Google or Twitter have solved these problems internally in a way that is idiosyncratic to their engineering processes. Earthly is the first solution to bring the power of repeatable builds at scale to market in a packaging that can fit all organizations.
D2iQ (formerly Mesosphere) simplifies enterprise Kubernetes in production at scale.

Why do developers ❤️ Earthly?
Cache build steps automatically
Earthly uses the same caching technology as the Docker builder. If a step of your build would produce the same output as a previously cached run, it uses the cache. Earthly cache can also be shared via the cloud.

Building things
Earthfile
FROM golang:1.13-alpine3.11
WORKDIR /proto-example
proto:
FROM namely/protoc-all:1.29_4
COPY api.proto /defs
RUN --entrypoint -- -f api.proto -l go
SAVE ARTIFACT ./gen/pb-go /pb AS LOCAL pb
build:
COPY go.mod go.sum .
RUN go mod download
COPY +proto/pb pb
COPY main.go ./
RUN go build -o build/proto-example main.go
SAVE ARTIFACT build/proto-example
Self-contained builds that work everywhere
No need to ask your team to install protoc, a specific version of Python, Java 1.6 or the .NET Core ecosystem. You only install once, in your Earthfile, and it works for everyone. Or even better, you can just make use of the rich Docker Hub ecosystem.
Parallelization with no strings attached
Whenever possible, Earthly automatically executes targets in parallel.
If your build has independent steps, Earthly will:
Checked bullet
Build a directed acyclic graph
Checked bullet
Isolate execution of each step
Checked bullet
Run independent steps in parallel
Checked bullet
Cache results for future use

Earthfile
FROM node:13.10.1-alpine3.11
WORKDIR /example-multirepo
docker:
RUN npm install -g http-server
COPY github.com/earthly/earthly-example-multirepo-static:main+html/* ./
COPY github.com/earthly/earthly-example-multirepo-js:main+build/* ./
EXPOSE 8080
ENTRYPOINT ["http-server", "."]
SAVE IMAGE --push earthly/examples:multirepo
Modern import system
Copy artifacts across repositories in a single line. Earthly is cache-aware, based on the Git commit sha of the referenced repository. Combined with shared caching, you can create vast and efficient build hierarchies that only execute steps impacted by your changes.
