Script + Dockerfile for building a Docker image based on node:20-alpine with Bun installed

Docker Hub page

The official over/bun image is based on Debian and doesn't come with nodejs which currently breaks compatibility with certain use cases.

This image is based on Linux Alpine (which is already being used with most Docker builds for NextJS, Vite, etc.),
comes with bun + node and npm installed (which is useful for maintaining compatibility in case of issues with Bun)

It also comes with glibc installed, which is currently a necessary fix to run Bun on Linux Alpine (oven-sh/bun#5545)

# Pull the latest version
FROM squishyu/bun-alpine:latest

Or

# Pull a specific Bun version
FROM squishyu/bun-alpine:1.0.2

docker pull squishyu/bun-alpine

To enter interactive shell:

docker run --rm -it --entrypoint sh squishyu/bun-alpine
