Chainguard Container for nemo

NVIDIA NeMo Framework is an end-to-end, cloud-native framework to build, customize, and deploy generative AI models anywhere.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/nemo:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Running the Image

To run the NeMo Chainguard Image interactively in an environment with connected GPU:

docker run -it --rm \
  --gpus all \
  --shm-size=8g \
  --ulimit memlock=-1 \
  --ulimit stack=67108864 \
  cgr.dev/chainguard/nemo:latest

These options allow access to connected GPU, allocate more shared memory to the container, and put an upper bound on container memory use. If you are running the image in an environment without connected GPU, omit the --gpus all option.

Testing GPU Access

If your environment has connected GPUs, you can check that NeMo has access. First, run the NeMo Chainguard Image interactively with the above command. At the container prompt, run:

$ python
Python 3.11.9 (main, Apr  2 2024, 15:40:32) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from nemo.core import pytorch_lightning
>>> len(pytorch_lightning.accelerators.find_usable_cuda_devices())
1

The above result shows that the environment has one connected GPU.

Testing NeMo

You can run the below commands on your host machine to download and execute a script to test NeMo functionality. The script uses two pretrained models to generate audio output from plain text (text to speech).

mkdir nemo-test && cd nemo-test
curl https://raw.githubusercontent.com/chainguard-dev/nemo-examples/main/tts.py > tts.py
docker run -it --rm \
  --gpus all \
  --user root \
  --shm-size=8g \
  --ulimit memlock=-1 \
 --ulimit stack=67108864 \
  -v $PWD:/home/nonroot/nemo-test \
  cgr.dev/chainguard/nemo:latest \
  -c "python /home/nonroot/nemo-test/tts.py"

After running the below, you should have a test.wav file in the current working directory on your host machine. The above example uses a root login in order to write the output to the volume. Remember not to use root or privileged access in a production scenario.

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
