Minimal image with buck2 build system binaries and toolchain.

Chainguard Images are regularly-updated, minimal container images with low-to-zero CVEs.

Download this Image

This image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/buck2:latest

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

Usage

The default entrypoint is set to the buck binary, and a default C/C++ toolchain is installed in the image.

docker run cgr.dev/chainguard/buck2:latest
buck2 8cb388050e28f9386ccc2458d6dcf55137e2f3b13008b2a13000994b38c496db <local>
A build system

Documentation: https://buck2.build/docs/

USAGE:
    buck2 [OPTIONS] <SUBCOMMAND>

OPTIONS:
    -h, --help
            Print help information

        --isolation-dir <ISOLATION_DIR>
            Instances of Buck2 share a daemon if and only if their isolation directory is identical.
            The isolation directory also influences the output paths provided by Buck2, and as a
            result using a non-default isolation dir will cause cache misses (and slower builds)

            [env: BUCK_ISOLATION_DIR=]
            [default: v2]

    -v, --verbose <NUMBER>
            How verbose buck should be while logging. Values: 0 = Quiet, errors only; 1 = default; 2
            = more info about errors; 3 = more info about everything

            [default: 1]

    -V, --version
            Print version information

What are Chainguard Images?

Chainguard Images are a collection of container images designed for security and minimalism.

Many Chainguard Images are distroless; they contain only an open-source application and its runtime dependencies. These images do not even contain a shell or package manager. Chainguard Images are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a secure software supply chain.

The main features of Chainguard Images include:

-dev Variants

As mentioned previously, Chainguard’s distroless Images have no shell or package manager by default. This is great for security, but sometimes you need these things, especially in builder images. For those cases, most (but not all) Chainguard Images come paired with a -dev variant which does include a shell and package manager.

Although the -dev image variants have similar security features as their distroless versions, such as complete SBOMs and signatures, they feature additional software that is typically not necessary in production environments. The general recommendation is to use the -dev variants only to build the application and then copy all application artifacts into a distroless image, which will result in a final container image that has a minimal attack surface and won’t allow package installations or logins.

That being said, it’s worth noting that -dev variants of Chainguard Images are completely fine to run in production environments. After all, the -dev variants are still more secure than many popular container images based on fully-featured operating systems such as Debian and Ubuntu since they carry less software, follow a more frequent patch cadence, and offer attestations for what they include.
