envd

What is envd?

envd (ɪnˈvdɪ) is a command-line tool that helps you create the container-based development environment for AI/ML.

Creating development environments is not easy, especially with today's complex systems and dependencies. With everything from Python to CUDA, BASH scripts, and Dockerfiles constantly breaking, it can feel like a nightmare - until now!

Instantly get your environment running exactly as you need with a simple declaration of the packages you seek in build.envd and just one command: envd up!

Why use envd?

Environments built with envd provide the following features out-of-the-box:

Simple CLI and language

envd enables you to quickly and seamlessly integrate powerful CLI tools into your existing Python workflow to provision your programming environment without learning a new language or DSL.

def build():
    base(dev=True)
    install.conda()
    install.python()
    install.python_packages(name = [
        "numpy",
    ])
    shell("fish")
    config.jupyter()

Isolation, compatible with OCI image

With envd, users can create an isolated space to train, fine-tune, or serve. By utilizing sophisticated virtualization technology as well as other features like buildkit, it's an ideal solution for environment setup.

envd environment image is compatible with OCI image specification. By leveraging the power of an OCI image, you can make your environment available to anyone and everyone! Make it happen with a container registry like Harbor or Docker Hub.

Local, and cloud

envd can now be used on a hybrid platform, ranging from local machines to clusters hosted by Kubernetes. Any of these options offers an efficient and versatile way for developers to create their projects!

$ envd context use local
# Run envd environments locally
$ envd up
...
$ envd context use cluster
# Run envd environments in the cluster with the same experience
$ envd up

Check out the doc for more details.

Build anywhere, faster

envd offers a wealth of advantages, such as remote build and software caching capabilities like pip index caches or apt cache, with the help of buildkit - all designed to make your life easier without ever having to step foot in the code itself!

Reusing previously downloaded packages from the PyPI/APT cache saves time and energy, making builds more efficient. No need to redownload what was already acquired before – a single download is enough for repeat usage!

With Dockerfile v1, users are unable to take advantage of PyPI caching for faster installation speeds - but envd offers this support and more!

Besides, envd also supports remote build, which means you can build your environment on a remote machine, such as a cloud server, and then push it to the registry. This is especially useful when you are working on a machine with limited resources, or when you expect a build machine with higher performance.

Knowledge reuse in your team

Forget copy-pasting Dockerfile instructions - use envd to easily build functions and reuse them by importing any Git repositories with the include function! Craft powerful custom solutions quickly.

envdlib = include("https://github.com/tensorchord/envdlib")

def build():
    base(dev=True)
    install.conda()
    install.python()
    envdlib.tensorboard(host_port=8888)

def tensorboard(
    envd_port=6006,
    envd_dir="/home/envd/logs",
    host_port=0,
    host_dir="/tmp",
):
    """Configure TensorBoard.

    Make sure you have permission for `host_dir`

    Args:
        envd_port (Optional[int]): port used by envd container
        envd_dir (Optional[str]): log storage mount path in the envd container
        host_port (Optional[int]): port used by the host, if not specified or equals to 0,
            envd will randomly choose a free port
        host_dir (Optional[str]): log storage mount path in the host
    """
    install.python_packages(["tensorboard"])
    runtime.mount(host_path=host_dir, envd_path=envd_dir)
    runtime.daemon(
        commands=[
            [
                "tensorboard",
                "--logdir",
                envd_dir,
                "--port",
                str(envd_port),
                "--host",
                "0.0.0.0",
            ],
        ]
    )
    runtime.expose(envd_port=envd_port, host_port=host_port, service="tensorboard")

Getting Started 🚀

Requirements

• Docker (20.10.0 or above)

Install and bootstrap envd

envd can be installed with pip, or you can download the binary release directly. After the installation, please run envd bootstrap to bootstrap.

pip install --upgrade envd

After the installation, please run envd bootstrap to bootstrap:

envd bootstrap

Read the documentation for more alternative installation methods.

You can add --dockerhub-mirror or -m flag when running envd bootstrap, to configure the mirror for docker.io registry:

envd bootstrap --dockerhub-mirror https://docker.mirrors.sjtug.sjtu.edu.cn

Create an envd environment

Please clone the envd-quick-start:

git clone https://github.com/tensorchord/envd-quick-start.git

The build manifest build.envd looks like:

def build():
    base(dev=True)
    install.conda()
    install.python()
    # Configure the pip index if needed.
    # config.pip_index(url = "https://pypi.tuna.tsinghua.edu.cn/simple")
    install.python_packages(name = [
        "numpy",
    ])
    shell("fish")

Note that we use Python here as an example but please check out examples for other languages such as R and Julia here.

Then please run the command below to set up a new environment:

cd envd-quick-start && envd up

Set up Jupyter notebook

Please edit the build.envd to enable jupyter notebook:

def build():
    base(dev=True)
    install.conda()
    install.python()
    # Configure the pip index if needed.
    # config.pip_index(url = "https://pypi.tuna.tsinghua.edu.cn/simple")
    install.python_packages(name = [
        "numpy",
    ])
    shell("fish")
    config.jupyter()

You can get the endpoint of the running Jupyter notebook via envd envs ls.

$ envd up --detach
$ envd envs ls

[!NOTE] Start from envd v1.0, v1 syntax is the default syntax for build.envd file, and moby-worker is the default builder.

Features	v0	v1
is default for envd<v1.0	✅	❌
support dev	✅	✅
support CUDA	✅	✅
support serving	⚠️	✅
support custom base image	⚠️	✅
support installing multiple languages	⚠️	✅
support moby builder	❌	✅

[!IMPORTANT] For more details, check the upgrade to v1 doc.
