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 project 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.
