sidebundle

English | 中文

sidebundle builds relocatable bundles from ELF executables (dynamic or static) and shebang scripts. The CLI can collect entries from the host filesystem or from OCI images (Docker/Podman), trace runtime-loaded files, and emit a portable bundle directory with launchers and a manifest.

2.Image usage: Extracting a shebang script (javascript) and its underlying ELF dependency (node) from a Docker (or podman) image and running it perfectly in a completely different Linux environment.

Install

• GitHub Releases (recommended): docs/install_en.md
• Build from source: docs/install_en.md

Quick start (static binary)

Grab the prebuilt musl-linked binary from GitHub Releases (e.g. sidebundle-x86_64-musl or sidebundle-aarch64-musl). It runs on any modern Linux without extra dependencies.

Scenario A: Ship a Python script to machines without Python

Assume your script has a proper shebang (e.g. #!/usr/bin/env python3):

./sidebundle-x86_64-musl create \
  --name hello-py \
  --from-host "./examples/hello.py" \
  --out-dir bundles \
  --trace-backend combined \
  --log-level info

hello-py/bin/hello.py will run Python from the bundle, even on hosts without Python installed.

Scenario B: Extract jq from an Alpine image to run on Ubuntu

./sidebundle-x86_64-musl create \
  --name jq-alpine \
  --from-image "docker://alpine:3.20::/usr/bin/jq::trace=--version" \
  --out-dir bundles \
  --image-trace-backend agent-combined \
  --log-level info

The resulting jq-alpine/bin/jq is a portable launcher that uses the bundled libs; Docker is only needed at build time.
