Examples of CI integration

Examples of integrating Earthly into various CI systems can be found on the following pages:

• Circle CI

• GitHub Actions

• AWS CodeBuild

• Jenkins

• Kubernetes

For more general information on CI systems not listed above, see the CI integration guide.

Examples by dev environments

Examples of how Earthly can be integrated into different dev environments

• GitHub Codespaces - shows how Earthly can be used in GitHub Codespaces and Devcontainers

Example Earthfiles

In this section, you will find some examples of Earthfiles to familiarize yourself with Earthly.

The code for all the examples is available in the examples GitHub directory.

Examples from the Basics tutorial

If you are new to Earthly, you may find the Basics tutorial helpful.

Examples by use-cases

• integration-test - shows how WITH DOCKER and docker-compose can be used to start up services and then run an integration test suite.
• monorepo - shows how multiple sub-projects can be co-located in a single repository and how the build can be fragmented across these.
• multirepo - shows how artifacts from multiple repositories can be referenced in a single build. See also the grpc example for a more extensive use-case.

Examples by Earthly features

• import - shows how to use the IMPORT command to alias Earthfile references.
• cutoff-optimization - shows that if an intermediate artifact does not change, then the rest of the build will use the cache, even if the source has changed.
• multiplatform - shows how Earthly can execute builds and create images for multiple platforms, using QEMU emulation.
• multiplatform-cross-compile - shows has through the use of cross-compilation, you can create images for multiple platforms, without using QEMU emulation.

Examples by use of other technologies

• grpc - shows how to use Earthly to compile a protobuf grpc definition into protobuf code for both a Go-based server, and a python-based client, in a multirepo setup.
• terraform - shows how Terraform could be used from Earthly.

Other

• readme - some sample code we used in our README.
• tests - a suite of tests Earthly uses to ensure that its features are working correctly.

Earthly's own build

As a distinct example of a complete build, you can take a look at Earthly's own build. Earthly builds itself, and the build files are available on GitHub:

• Earthfile - the root build file
• buildkitd/Earthfile - the build of the Buildkit daemon
• AST/parser/Earthfile - the build of the parser, which generates .go files
• tests/Earthfile - system and smoke tests
• earthfile-grammar/Earthfile - the build of the VS Code extension

To invoke Earthly's build, check out the code and then run the following in the root of the repository
