discussion(lang): How to support multi-target

[gaocegege]

Machine learning does not only include training. You may also need to process data/serving.

You as the user may want to build a separate image for a specific purpose. Thus we may need to support:

version = "2.9.1"

def dev_env(version):
    # Use nvidia/cuda:devel image
    base(runtime="devel")
    install.python_packages(name=[
        "tensorflow=="+version,
        "tensorboard"
    ])
    config.jupyter(password="", port=8888)
    shell("zsh")
    config.vscode(extension=[
        "ms-python.python"
    ])

def serving_env(version):
    base(runtime="runtime")
    install.python_packages(name=[
        "tensorflow=="+version,
    ])

def build():
    cuda(version="11.6", cudnn="8")
    dev_env(version)

def serve():
    serving_env(version)
    cuda(version="11.6", cudnn="8")
    entrypoint("python server.py")

You can run envd build --func build or envd build --func serve to build dev/serving images.

I'd appreciate it if you could give some feedback as the end user.

The design looks like a similar describe structure in Makefile but in a more human readable way. Cool for me!

Bazel: https://docs.bazel.build/versions/main/tutorial/cpp.html#specify-multiple-build-targets

cc_library(
    name = "hello-greet",
    srcs = ["hello-greet.cc"],
    hdrs = ["hello-greet.h"],
)

cc_binary(
    name = "hello-world",
    srcs = ["hello-world.cc"],
    deps = [
        ":hello-greet",
    ],
)

CLI

bazel build //main:hello-world
