fc-busybox

BusyBox static builds for E2B sandbox VMs.

What this builds

A BusyBox binary with default config (all standard applets including ash shell), statically linked with musl libc for both amd64 and arm64.

The sandbox init script uses #!/usr/bin/busybox ash, so ash and the full default applet set must be present.

Usage

Push a tag to trigger a build and release:

git tag v1.36.1
git push origin v1.36.1

Local build

sudo ./build.sh                          # host arch
sudo TARGET_ARCH=arm64 ./build.sh        # arm64
sudo BUSYBOX_VERSION=1.37.0 ./build.sh   # custom version

Output: builds/{version}/{arch}/busybox
