PyPy is a fast and compliant implementation of the Python language.
Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev
:

This image is comparable to the pypy/pypy image, with the following differences:
pypy
features a stripped down, minimal designThe PyPy Chainguard Image provides a minimal PyPy runtime suitable for workloads such as web applications, CLI utilities, interfacing with APIs, or other tasks. Currently Pypy only supports pypy-3.11 and pypy-3.10 which are also available as chainguard images.
We have two image variants available:
pypy:latest-dev
variant that contains the pip
, pypy
, and apk
package managers and the bash
, ash
, and sh
shells.cgr.dev
, run the following:The minimal runtime can be used to run an application that doesn't need non system wide packages and or a linux shell. An example hash.py function is given below;
To execute the code above in a pypy container, run the following
To pull the dev variant, run this command:
To access the shell in the pypy:latest-dev
image, you'll need to include an --entrypoint
option, as in the following example:
If you require additional packages that can be installed with the pip
package manager, we recommend using a multistage build. This process involves installing packages in a virtual environment using the latest-dev
variant, then copying this environment over to the minimal runtime image.
The following is a minimal example of a Dockerfile that uses a multistage build to run an app.py
script after installing dependencies:

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:
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.
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.
