Download this Image

The image is available on cgr.dev:

docker pull cgr.dev/chainguard/busybox:latest

Upcoming Changes

On July 15, 2024 the busybox:latest image will move from a Alpine base to a Wolfi base, in-line with all other images in our registry. We do not expect this to cause breakages, but encourage all users to test and verify the new version.

You can test today by migrating to the cgr.dev/chainguard/busybox:latest-glibc image. From July 15, the :latest and :latest-glibc will point to the same image.

Full details are in this blog post.

Usage

Chainguard offers two different variations of the busybox Image. Both contain the BusyBox software but are built against different variants of libc:

• latest, meant for variants based on musl
• latest-glibc, meant for variants based on glibc

You can ensure that either of these Images are working correctly by testing that they can run commands and return output. The following commands will both return hello world! in your terminal:

musl:

docker run -it cgr.dev/chainguard/busybox:latest echo hello world!

glibc:

docker run -it cgr.dev/chainguard/busybox:latest-glibc echo hello world!

Also, note that you can open an interactive shell on either version of the Image with command like the following:

docker run -it cgr.dev/chainguard/busybox:latest sh
