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

Where Does Earthly Fit?

Where does earthly fit

Before:

  * Clunky
  * Flaky
  * Build guru required

After:

  * Reproducible
  * Understandable
  * No build expert required

With Earthly, all builds are containerized, repeatable, and language
agnostic.

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.

Benefits

  * Repeatable builds
  * A familiar syntax
  * Caching for more speed

Earthfile FROM golang:1.13-alpine3.11 RUN apk --update --no-cache add
git WORKDIR /go-example all: BUILD +lint BUILD +docker build: COPY
main.go . RUN go build -o build/go-example main.go SAVE ARTIFACT
build/go-example AS LOCAL build/go-example lint: RUN go get
golang.org/x/lint/golint COPY main.go . RUN golint -set_exit_status .
/...

A simple GO example

zsh Building things

Invoke a build using earthly +all.

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.

    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 love Earthly?

Cache build steps automatically

Caching that just works

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.

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.

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

Parallelization with no strings attached

Whenever possible, Earthly automatically executes targets in
parallel.

If you build has independent steps, Earthly will

  * Build a directed acyclic graph
  * Isolate execution of each step
  * Run independent steps in parallel
  * Cache results for future use

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.

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
