Chainguard Container for pixi

Cross-platform, multi-language package manager and workflow tool built on the foundation of the conda ecosystem.

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/pixi:latest

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

Compatibility Notes

The Chainguard Pixi Image is comparable to the Pixi Image from GHCR. However, the Chainguard image contains only the minimum set of tools and dependencies needed to function. This means it doesn't include things like a package manager.

Getting started

The quickest way of getting started with this image is by using docker:

docker run --rm -it cgr.dev/ORGANIZATION/pixi:latest

You can then run the pixi CLI via docker by running docker run:

docker run --rm -it cgr.dev/ORGANIZATION/pixi:latest pixi search numpy

Example: HTTP server using external library

The following build demonstrates how a standard HTTP server could be implemented using Chainguard's Pixi development image.

First, create a project folder and change the working directory to that folder:

mkdir -p ~/pixi-http-server && cd $_

Next, write a file defining your HTTP server (main.py):

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "<p>Hello, World!</p>"

Write a Dockerfile to define our image build:

FROM localhost:5005/pixi:latest-dev

WORKDIR /srv/http

COPY ./main.py /srv/http/main.py

RUN pixi init
RUN pixi add python flask

CMD [ ".pixi/envs/default/bin/flask", "--app", "main", "run", "--host", "0.0.0.0" ]

Build the image, tagging it pixi-http-server:

docker build -t "localhost/pixi-http-server:latest" .

Run the image exposing the port defined in the application code:

docker run -p 5000:5000 localhost/pixi-http-server:latest

You should see output similar to the following on the container logs:

 * Serving Flask app 'main'
 * Debug mode: off
 * Running on all addresses (0.0.0.0)
 * Running on http://127.0.0.1:5000
 * Running on http://172.17.0.3:5000
Press CTRL+C to quit

When fetching the contents of 127.0.0.1:8080 via a tool like curl, you will see the following:

curl 127.0.0.1:5000

<p>Hello, World!</p>

What are Chainguard Containers?

Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.

All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system 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 development, or -dev, variant.

In all other cases, including Chainguard Containers tagged as :latest or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.

Although the -dev container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev variant into a more minimal production image.

Need additional packages?

To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl, or API.

To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
