# Earthly Intro: https://docs.earthly.dev/
# Earthfile Reference: https://docs.earthly.dev/docs/earthfile

# Quick notes:
    #   • The shell script at ".evergreen/earthly.sh" can be used to automatically
    #     download and use a fixed version of Earthly that is compatible with
    #     this file version. Execute the shell script as if it were the Earthly
    #     executable itself.
    #   • In this file, the convention is to copy the source tree into /s/libmongocrypt
    #   • Earthly copies the "build context" (working directory) into the local buildkit
    #     daemon before each build execution. (Similar to the Docker build context).
    #     If you have a large amount of data in the working directory, this could be
    #     slow. The ".earthlyignore" file specifies patterns of files and directories
    #     to exclude from the context upload. Modify it to suite your needs, if necessary.
    #   • Only a subset of the source tree is COPY'd into the build environment. Files
    #     outside of this set will not be available in the build. See the COPY_SOURCE
    #     command for the list.
    #   • Modification at any layer will invalidate caching on all subsequent build
    #     layers. This is important and by-design in Earthly. Push infrequently-modified
    #     operations to earlier in the process the pipeline to make better use of
    #     the cache.
    #
    # This file has a few major sections:
    #   - Setup COMMANDs
    #   - Utility COMMANDs
    #   - Environment targets
    #   - Build/test/CI targets
    #
    # All environment targets begin with "env.". All build targets (should) accept an "env"
    # parameter that specifies the name of the environment to use for the task. The name
    # of an environment is specified following the "env." prefix. For example, the
    # Ubuntu 22.04 environment is named "u22", so its environment target is "env.u22",
    # and can be used i.e. "earthly +build --env=u22"
    #
    # The following environment are defined in this file:
    #   • u22 - Ubuntu 22.04
    #   • u20 - Ubuntu 20.04
    #   • u18 - Ubuntu 18.04
    #   • u16 - Ubuntu 16.04
    #   • u14 - Ubuntu 14.04
    #   • rl8 - RockyLinux 8 - Stand-in for RHEL 8
    #   • c7 - CentOS 7 - Stand-in for RHEL 7
    #   • c6 - CentOS 6 - Stand-in for RHEL 6
    #   • amzn1 - AmazonLinux (2018.03)
    #   • amzn2 - AmazonLinux 2
    #   • deb9 - Debian 9.2
    #   • deb10 - Debian 10.0
    #   • deb11 - Debian 11.0
    #   • deb12 - Debian 12.0
    #   • sles15 - OpenSUSE Leap 15.0
    #   • alpine - Alpine Linux 3.18
    #
    # When adding new environments, always pull from a fully-qualified image ID:
    #   • DO NOT: "ubuntu"
    #   • DO NOT: "ubuntu:latest"
    #   • DO NOT: "ubuntu:22.10"
    #   • DO: "docker.io/library/ubuntu:22.10"
